The important thing to ask is 'how long'? Is this happening in a 1/4 mile race? At the end of a straight? Free revving? The biggest reason for a 7qt oil pan is the fact that the stock pan does not contain enough oil for the engine to actually pump it all to the top end and have time to drain back to the sump to be pumped up again. You may simply be sucking oil out of the pan and throwing it to the top of the engine where it resides long enough that you are sucking air simply because drainback can not occur fast enough. "Accusump is your friend!"

Speaking of how it was for older generations...I concede I didn't have it as bad as these guys: Track 21 Monty Python the Final Rip Off Disc 1 (25-03-2009 14-41-59).mp3

"Also Tony, what was your goal when you decided to read that out loud to your friend? I don't necessarily appreciate you making a joke out me or my situation, although its uplifting on a very minuscule level. My words to anyone who say "back in my day they paddled me"... its not your day anymore, its my day and in my day some of those things don't happen." Uh, this is a classic case of someone doing something and then getting self concious about it in retrospect. And you single ME out for reading it out loud. As if putting it on the internet is some solemn pristine place where privacy and personal discretion is the watchword. Give me a break! At least I was HONEST about what I did, and what comments were received. I know there are FAR more people who feel the same way about it upon reading your 'whining lament'... I was a big 'don't give me "Iustas" dude!' kinda guy. I didn't care what guys USED to do when they were my age blah blah blah. Usually when it came to people making ignorant commentary about things which are UNSAFE. In your day you don't WANT things to happen. But I'll remind you my classes were hard as hell, and I passed. I am not the one failing. Consider that you simply aren't up to it. I didn't whine about it, I knuckled down and passed. "I have been there" but you don't like it because I'm not a touchy-feely in-touch with my female talk about it side. I preferred then, and prefer now not to whine and lament my position in life. Instead I choose to do something about it, as it's MY business. Soon as you put it out there for comment, you loose the right to whine about what someone thinks about your whining!

In this case, venting to atmosphere would be all that is required. Remember the wastegate is now controlling to peak efficiency speed and will only open when the overspeed of the wheel is looking like it would occur. Generally, venting to the lowest pressure place would be the best, and that would be the plenum under the air cleaner to blow backwards through the filter to dislodge debris. Blowing into the turbine won't really keep the speed up, the wastegate isn't controlling the boost any longer under this control scheme. The wastegate controls turbine speed, and the BOV is now the effective pressure-control valve! On an aside, there was a device called the "Miller Woods Turbo Group Fueler" which had a fuzzy logic control of the wastegate to severely overboost the engine at lower engine speeds, using excess capacity of the fuel system to supply fuel at lower engine speeds. As the engine speeded up, the fueler tapered boost back so the stock injectors could make the horsepower requirements. Their philosophy was that if you can supply fuel for 200HP at 6000 rpms, then you can DOUBLE your torque at 3000 rpms by boosting higher at 3000 than you can at 6000. Really amplifying the low-speeed response of the vehicle. They basically douobled the boost and the injector pulsewith was moved to 'full load/full rpm' type of mapping at the lower engine speeds, porportionally adjusted depending on what kind of response you had in mind. Great profit for them...Not a lot inside, but the chips.....ooooh, the chips!

Kill? I'm Italian, and the revenge went something like this: 10 years to the DAY HOUR MINUTE SECOND that he puked on my floor, I called his house. When his daughter answered the phone she was told to ask her daddy 'What were you doing 10 years ago today, daddy?' Who is that on the phone? 'He says "guess"---what were you doing 10 years ago this second daddy?' Ten years ago, ten years ago? Hmmmm Can he give me a hint? 'The Toy starring Richard Pryor' Hmmmmm 'Daddy, why is Bacardi and graham crackers on an empty stomach a bad idea?' DIGHERA! GIVE ME THAT PHONE HONEY?!?!?!?! What do you do, dude, write this shite down or what? (hear in the background: "Mommy, what is Bacardi? Will I get sick if I eat graham crackers?" Actually, I did, and I figured I'd scratch your brain about why you didn't listen to me and get out of my F-ing van when I told you to! (hear in the background a little girl getting agitated "But I don't WANT to get sick mommy! I LIKE graham crackers!" Besides, he slipped on his own slick and bashed his head on the backside of the floor as he went out on his arse...and I was laughing so hard I almost peed myself. Of course all the cheerleaders were around saying "Is that XXXXXX XXXXXX getting sick?" Hey dude, I TOLD you to go to the bathroom, if you had listened and not tried to be Joe Cool Bob Bitchen and went to the bathroom you could have puked in private and everybody would think you were still some cool drinking gawd. Now you're "XXXXX-the-Puker"---and that's going to stick. And one day, 10 years from now, you will get a phone call and I will REMIND you of this day, and make you THINK about what you did! And I did. And his daughter gave him hell for 13 more years after that call!

Swarf has been my bane the past week in Japan. We had a sudden rotor failure, and when disassembling the machine at site didn't really see anything. But back at the shop, found an aluminum chip in an injection nozzle feeding the side of the machine that failed. This is VERY odd as we have 100% wetted parts of stainless steel in the oil system, and the gearbox is an obvious ferrous casting. So the question is 'WTF is this aluminum chip doing in there, and where did it come from?' I don't think this one had caused preblems yet. But in another incidence back in May there was a serious swarf infarction that took out the high speed bearings on another machine with a similar non-ferrous swarf chunk in the nozzle. But there was ferrous stuff in the bearings like a gallery wasn't flushed properly at assembly or something. I can live with that one, we can see where it came from on THAT machine. This one.... WTF? Where did the mystery swarf come from? It almost appears to contradict the disproval of spontaneous generation! On the Aeromotive Regs, JeffP had one all full of machining chips that wouldn't let the regulator seat so it would bleed down and was hard to adjust. Take it apart and clean it all up...and notice there are cuts in the diaphragm... Replace and since then it's worked flawlessly. But that first attempt at fuel regulation was a dismal abyss of failure. A vendor who saw the install commented similar items had occurred to his customers. Maybe they had a bad batch and some are on the shelf? I'd disassemble and check like I do with Harbor Freight stuff...just to give me peace of mind. They never fail 'rich safe' damnit!

Actually having the raw pulls would satiate my curiosity more than answer some 'documentation' claim. If Knepp says it was, that's good enough for me. The pull here on the GTP car is interesting for the boost response, it reveals some stuff I suspected but couldn't be absolutely sure about. I think the E-motive pulls would be equally enlightening! Even if they weren't 'all out' top power pulls...

I have a bag and a backpack when I leave, but usually THREE BIG bags on the way home. Put the back seat down and it all fits nicely. And it tows the coupe around the yard with aplomb! They do tow trailers nicer than the coupes do... From my experience that is... It was a 'demand filler' to be sure. They would loose buyers when they had a kid. Face it, younger guys bought Z's because they didn't NEED a back seat. I bought it so I didn't have to give anybody a ride "Sorry man, 2 seater, I can only take her..." I had a Microbus if I wanted to move big things. And then, I took the back seats out so I wouldn't have to haul around too many drunks at the end of the night. Working the hose when I got home got tedious. Friendship can only go so far, and puke on the carpet kills most of that.

Yeah, that is about right. I found with Europe that booking the freight from the USA is considerably cheaper than booking on that end. Same price but one is dollars and one is Euros! And you can fit more than three in there, with a Hi-Cube you can fit 6 S30's, a front clip, a bicycle, a 50,000 btu BBQ unassembled in it's box, and more FRP and parts than you can even start to imagine! LOL With a couple of reliable friends, the economics of shipping cars becomes nice. Four guys sharing a container (easy packing for four) makes your individual shipping costs only about $1200 a car, including almost an unlimited supply of space for parts. If you can get laydown service for the container at both ends (where it physically lays on the ground and not up on the wheels) you're golden!

Actually, last evening I was sitting in my room with another engineer who works in our R&D section, and was reading your original post outlound and I basically 'channelled' him on the first post. To be honest when we went to Wal-Mart he actually (and this is the truth) picked up a package of panty shields and said something about giving them to 'that whining kid on that internet post you were reading me earlier tonight'! The LOL at the concentration camp guards comment was me. I found that funny as hell. There was a point where I had drawn a cartoon of someone with an "Arbiet Macht Frei" sign in the background as an overlooked charge digillently applied himself in his research time after class...the caption being 'why does this guy study so hard? Is Prof X really that bad?' Remember, I had a high school shop teacher that THREW things at you if you asked a stupid question. And his contention was that there IS a such thing as a stupid question: the one you don't put enough thought into YOURSELF before you ask! I have to say, even though there were trials...afterwards I have not failed at any task assigned to me. Either I'm classically selecting easy assignments and taskings, or I was well prepared by classes and practical training. I can not say 'school was easy' after high school. It did take all my attention. Actually that is really what is going on, some people don't know how to focus their attention. Fear is a great motivator. Some of this isn't applicable later on, but the concept of focus and application of all energies in a singular direction IS something that will pay off no matter what you do. And the business knocks were mainly due to many of the guys I knew who 'went to the dark side'---a good guy I know at a major competitor who was working towards his BSMET, and though he was hauling a 3.8+ GPA, just changed to business management in his 3rd year. Why? Because in his exact words: "I looked at what I was going to make, and it didn't make any sense. I'm busting my balls and won't get $80K. If get a business degree with what I already have (AA in MET, along with 10 years in the engineering field) and I can start at $100K+ as a manager." At least he was honest. And he was right. If he'd followed the engineering goal he would be overworked in a cubie doing aerodynamic profiling or something on turbine blades. Instead he's a manager making six figures and he's done with school witohut nightmares. The change was 'like night and day, it was a breeze!' I worked with too many guys who had no engineering background and were souless MBA's with nothing more on their mind than their next 90 day performance bonus made on the backs of people like me who were in the field billing hours and providing something to the customer of value. If that happens, no trickery is needed to provide value for shareholders, the profits will come, and the dividends will follow. I watched a whiz-kid (my age, actually) throw away $12 million annually in service work to try and make a 'no touch' parts business. A pure pass-through mark it up and profit venture. The business technically 'grew'... and the service work was given away, another local business started up with 'overhead he eliminated' to provide services to the customers he didn't care about. And the company, while looking great on paper, failed when the house of cards fell. But he got his bonuses. He got a 'Best place to work in XXXX XXXXXXXX' gold star on his resume, while our engineering displaced former service manager and salesment and technicians.... they got a $12,000,000 GRANT for small business development from the state of XXXXXXXX. They used that to build one nice damn building/shop/inventory stockroom. As opposed to the old Tobacco Drying Barn we were working out of... This guy actually told Katrina Victims who bought used equipment from our company 'you bought used equipment, what do you expect?' Answer: I expect the MFer to at least RUN! Talk about destroy a company reputation. All about the money. And that brings me full circle on my digression to the money. You already have numbers in mind. Expectations. Most younger guys are all about the money. There are more important things. Be open to the fact that poor is not necessarily a bad thing if you are happy doing what you do.

That would be under the 'venting without external air source...' and is kind of difficult to do!

engine and tranny is needed for the GL that is sitting in the back yard... but if you want the L28 and Automatic that is in that one...it's yours!

That is the intent of the class! It has to be STOCK as it came from the factory. The limited exceptions are things that could make a hazard if they fly off at speed: Wiper Arms, Mirrors...but that's about it. No taping of seams, no ducting of radiators (unless stock...like the S130 Euro Duct I have...) This is about as stock a Stock Z as you can get! This feat is VERY impressive with the CD and Drag on that known and verified. DAMN impressive. Understand we only had about 280HP when we went near that same speed with the G-Nose, Light Covers, and Full Belly Pan! 100HP got him to where we were with aerodynamics. If we had used his engine our speeds would have been 'long track' eligible. BTW, our 'best speed' was a measured mile around 176mph, the two-way average was 173.325.

A Container (40 footer) should run that much! A car alone should be less than that unless you have a greedy broker!

"The professors are not concentration camp guards, signing thumbs up or thumbs down on who lives or dies." LOL "My experience appears different!" ROMAFLOL!

"manoeuvre noun ( MOVEMENT ) UK (US maneuver) /məˈnuË.vÉ™r//-vÉš/ n [C] a movement or set of movements needing skill and care Reversing round a corner is one of the manoeuvres you are required to perform in a driving test."

Yes, I may be an A$$, or an A-Hole, but I'm also one with four RHD vehicles that I have been driving in the USA continually since 1991. How many to you own? How many have you driven? "Yelling" is in fact the fact that were you in front of me I'd be RAISING my voice to punctuate the statement. You want to call it yelling, I call it PUNCTUATION! You made a statement based on reasoning without EVER having driven the vehicle. It's like you're giving sex advice as a virgin. You read about it someplace, and heard this or that....and are passing it on. I, on the other hand, am the RHD *****. Full of years of experience and willing to share whatever I have. And what I have is probably 100,000 miles+ of driving in RHD vehicles here in the states and never having ANY of the problems you SUPPOSE you will have. And again---you said you can't see past the vehicle. If you can't, YOU ARE TOO CLOSE! This is a FACT. Overtaking is not done from DIRECTLY BEHIND another vehicle! LHD or RHD. You state you have a valid point IN YOUR OPINION, and refuse to change it. I have one based on 20 years of EXPERIENCE---which one is more valid? Are they EQUALLY valid? Which should be subject to revision? Should it be the one based on 'thought'? Or the one based on EXPERIENCE? I might say that someone who has done it MIGHT (maybe) have a little more valid contribution to make. But you have discounted that, thrown it out or ignored it entirely. But I'm the terrible oagre here. Be open to the possiblity you have 'thought wrong'... That you are standing on a TECHNICAL point that in PRACTICAL everyday application means not jack shite! This IS a possiblity that has not occured to you, I can see that. Hopefully you will see it as well. Making a statement that RHD vehicles are DANGEROUS in the USA is plain ignorant. FACTS and hundreds of thousands of miles driven by THOUSANDS of RHD vehicles in the USA tend to make that point for me without having to argue. If it was a big deal, I'm sure the media and the regulators would make you convert them when importing (like in Australia---who curiously now has relaxed that requirement...wonder why?) Keep an open mind towards those who have done, especially when you haven't! "You never try to put insight on the subject. Instead you force your ideas on people, at the same time just bashing the others ideas. " Force my ideas? Is that the same as 'advocating a stance'? I thought that was what debate was about? If someone posts a wrongheaded idea, is it not right to conter point? I have counterpointed from experience a position you advocated from 'thinking about it'... If you are offended at the possibility that 'you thought wrong' or perhaps my examples cause you to doubt your position...maybe that's what it's intended to do. Making a ridiculous statement like "RHD Vehicles make Passing Dangerous and are Harder to Drive"---you haven't given any factual statement to support it in ether case. Harder to drive is plain wrong on the face. Passing Dangerous? It is inherently dangerous, but no more so than in an LHD vehicle. I have no visibility problems in an RHD vehicle. S30, S31, S130---got them all, along with having a Sunny Pulsar GTi-R that I scooted around in for a couple weeks. Not a problem. So what do you do with that, this is not being contrarian. Is it because I'm some Super Uber-Driver? I would like to think NOT. I would like to think I have no 'special driving powers'---so what explains the FACT that I do not experience the dread or problems you apparently experience when simply THINKING about RHD vehicles? How do you reconcile that?

You need to download the FSM and look at the wiring diagram. What happens to the gauge when you ground the yellow wire against the chassis---it should move one way all the way. When you remove it from ground it should go back the other way (whichever that was)... If it doesn't there's either a break in the line or no power to the front of the circuit (or a bad gauge)... You need to follow the circuit on the FSM wiring diagram, this one is not one I can do from memory!

BTW a statement of opinion is opent to attack if it's showing evidence of ignorance or incomplete thought. That someone brings up a different point that may be just as valid. Driving a VW Microbus, overtaking is a 'lay back, plan ahead' and I will say this: it is FAR easier for me to overtake in an RHD Z, and the safety is much higher being able to pass in the onciming for mere seconds, than it EVER was in a VW trying to pass someone at even 45 in a 55 zone! Laying back and passing with clear visibility is not anything all that difficult, especially when you have the power to pass. People have grown used to the interstates and I doubt driver's ed today even teaches proper overtaking. The position to overtake is NOT behind the vehicle so close that you can't see around it (LHD or RHD). And a statement that it's dangerous is plain wrong (and opinions CAN be wrong!) Don't make the move from ignorance to stupidity. Being ill informed or basing things on incomplete knowledge or assumptions is one thing. Being presented with evidence and steadfastly adhering and not being willing to even entertain the thought your original supposition was incorrect is the definition of something other than plain forgivable ignorance. When informed of the situation and the variables, refusing to change the stance is stupidity. With probably more miles behind a RHD vehicle in the USA than I ever drove in Japan in 5 years...I think I've got a pretty good idea of what it's like to drive an RHD here (probably 5 to 10K miles a year since getting my RHD here in SoCal in 1991) I also had to drive BIG USA Built LHD trucks in Japan. As well as smaller US Sedans (LHD) in the world of RHD (Japan, U.K.) The statement 'its dangerous' is the same as guys saying 'it's harder to shift with the other hand'---either there is a mental block or challenge, or you've never really done it. It's no great shakes. It doesn't take Yogi Bear to do this, my bud Drew can drive his RHD Celica here and he's not Steven Hawking when it comes to brain activity. Probably more along the line of Tommy Chong's Character in 'Up in Smoke'...when stoned. If he can do it, it's NOT that hard.

"Ok, senario, you are on a 2 lane road, behind a large truck, lets not even say a semi. The truck is traveling a lower rate of speed than you would like to. So, you would like to pass the truck. You cannot see the on comming traffic and you cannot get far enough over to see around the truck without putting you and your car in danger of on coming traffic. That is how it is dangerous. I don't see what is so damned hard to understand about that? Its dangerous to pass anyway, there is an increased risk passing on a two lane road in a right hand steer car. " YOu have never driven an RHD Drive Vehicle in America, have you? Nor an LHD Vehicle overseas. I have done both. It is neither dangerous or anything more than a driving adjustment that needs to be made. If you think 'laying back' doesn't give you room to pass, then you have spent FAR too much time driving on America's Interstates. Driving is a dead art here, nobody knows how to properly pass and it's evidenced by the TERRIBLE technique evinced in this ignorant rebuttal. Proper overtaking IS NOT DONE ON THE ASS OF THE VEHICLE YOU INTEND TO PASS! That's called TAILGATING and is EVEN MORE UNSAFE than any attmpted passing manouvre. If you are so close that you have to duck your car out into the oncoming lane to determine if it's 'clear' then you haven't been properly instructed on driving and overtaking and that's the end of the discussion in this thread. If you don't know how to drive, please don't blame the equipment. If you've never done it making an ASSumption leads to this kind of exchange. "It's Dangerous to Pass" is the ONLY thing you have said that has merit. LHD or RHD makes no difference. Two lane road or more, makes no difference. Your driving technique needs gross improvement!

Exactly, Tim!

Maybe it's the black wire that should be ground? The 240 does have ground and power on the connector and the wires all tend to have the same color back there after the years take their toll. The circuit, btw is on the ground side, the 'power' wire is actually the ground side of the gauge movement. The sender regulates the ground for the gauge and that is how you register fuel level. One wire is directly grounded to the chassis though. That keeps the sender which technically floats on that rubber o-ring, connected securely to ground of the chassis. The wire harness is grounded back there as well so there should be a decent ground path. Cleaning that ground point back there on the chassis should brighten up your tail lights as well!

"because it's there to catch vapors and condense them and return them to the tank." That's what 'phase separation' means John. I already conceded you win. Gas expansion is not an issue, and the incontravertable evidence that the 69Z's didn't have one proves beyond a shadow of a doubt that they are unrequired, and indeed were only put there to keep a relative employed who happened to make expansion tanks. 15 7/8 is not 16 since pendantic adherence to form was what was being required and the forest was obscured by all the trees... All I know is filling up on a winter morning and driving to work to let diurnal variation do it's thing on a black car will have fuel coming overboard out the filler neck vent (JDM fuel system) and puking fuel on the ground. This is not due to thermal expansion, it's due to bacterial breeding displacing the fuel. Or something else. Expansion is not the mechanisim causing the fuel to rise. That does not happen.

I used a 15mm to 10mm 90 degree nylon barbed adapter to make the transition easier. Also on the rearmost right tank vent (1/4") I made a "U" bend from stainless to make it fit better. All my vent lines are connected, but they are only 10mm or 5mm fuel line. I don't have to fill slowly, the 10mm seems to vent fine, you just need all the points connected. Maybe the combination of 10mm and 5mm off the back is what does it. On my 74, the back right vent is what I hooked up similar to what you did: Bring it up high in the "C" pillar above where the stock expansion tank is where I put an 'instrument loop' (double wrap about 3" radius) of fuel line, and then brought the line back outside the passenger's compartment and put the rollover valve and a small K&N Gauze filter on the end. Seems to work fine for me as well. As long as there is enough line volume to handle gas expansion when you fill up, nothing will pressurize or puke over. ( I still content gas expands when it gets hot...) Another thing nice is the fumes---I can put 5psig in my tank and it won't leak down over night. Any fumes I get I KNOW are not tank sourced. If you plug your carbon cannister vent line, or the diverter valve on the earlier 240's, you should be able to hold 2psi in the tank overnight. If you don't, you have a leaking line---most likely a vent, and it can cause gas fumes to be smelled. Main factor for me was cost as well, I put the fuel line conversion in years ago, and those lines are still fine. Even if they weren't the line is CHEAP to replace once the nylon conversion fittings are on there. These fittings were the same as Datsun used originally, I found them in a plumbing supply section at a hardware store. They had nylony, ABS, even brass. Since Nissan/Datsun used Nylon as an OEM choice, that's what I used, and they were cheaper than brass. Don't see a need for the weight and durability has not been an issue.

It's not a Pop Off Valve, as it's not something that opens to relieve pressure. It's not an unloading valve perse, because we are not unloading it. Really BOV is describing it's function, and in both cases it does exactly the same thing: keep the turbo from surging by relieving (blowing off) excess air to prevent the turbo compressor wheel from going into a low-flow surge event. It stabilizes minium flow rates through the compressor as it's primary function (blowing off excess flow) and at the same time allows shaping of the intake manifold pressure curve dependent on speed, throttle position, or whatever other variables you would choose to corporate. Traction control is a great example. If you had a small turbine housing you could keep the wastegate closed, and run some pretty high boost pressures at very low engine speeds. You blow off the excess to prevent a surge at that low a flow, but the engine doesn't care that you have 12psi at 1000 rpms, and are blowing off 75% of the air produced by the turbo---it only knows it's got all the air it needs to have 12psi in the inlet manifold and it produces power accordingly. That is the hardest thing for people to grasp---you will launch harder (if you have traction available) being able to launch at 12psi and run a midrange psi of 20 rather than the conventional thinking of getting 30psi but only after 3400 rpms or whatever. The 'area under the curve' is huge compared to conventional wastegate only control. And it's great I checked in this morning, that means I got to get the manuals form Bill today as I leave tomorrow from here!
