Recently my car has started doing some funny stuff. Its running pretty rough on startup, kinda feels like its missing or something. And on acceleration it stumbles kinda and feels like a subaru. I've checked the spark plugs and they were ok except for #6 which had quite a bit of oil build up on it and smelt like unburnt fuel. I cleaned them all to see if that was the problem. Put them back in car and started it and it ran good for about 1 minute then started doing its stumbly thing at idle... I had a play with the ignition timing aswell to try to see if i could set it straight, found a good setting for timing with the 10psi that i run so thats ok. But after driving that car for about 20 minutes it just got even more stumbly, but on boost you dont even notice it. I put a new distributor cap on yesterday aswell. the car is also drinking water slowly. Using about 400ml a day (i just topped it up with more or shell's coolguard). My lead are about 4 months old, one day i noticed they were leaking spark so i taped them up and i never noticed it again. Is the problem that i need new leads? Or what. I used to get a vacuum or between 17-18 at idle. Now its at like 14-16. Thats why i set the ignition timing. I dont know what to do. I have a feeling headgasket might be cracked somewhere as my water looked very mildly contaminated but my oil looks fine (its about 3 months old). Help.... Regards, George. next thing i type on another forum: ::Too make matters worst, last night after i got everything back together and went for a drive to test it out, it seemed to be running ok. Driving down the motorway i hit 105 and hear something in the back go clunk (not a big clunk but enough to notice it, and sounded like a tool falling off and hitting the ground [but i wasnt using a tool or doing anything to the diff]). It got pretty bad but only at 1550 rpm to 2150rpm on coasting, it was making this noise like a a broken gear, kinda like a clock ticking but also clunking it was pretty mild. Anyway i needed my vehicle so had to keep driving and couldnt really just stop on the motor way. I drove 15 km to SuperCheap Auto spares to get a new spark plug and lead for #6. As i was pulling into their carpark it started to misfire and was heating up pretty bad. Looked in the coolant bottle and it was pretty gross looking in there. Was contaminated with oil about 10%. I went and got the lead and plug, i put the lead on and drove home. It was a horrible drive, i was trying not to hit boost at all but i hit it once and big cloud of white smoke shot out the back. I thought "there goes the head gasket". The rest of the drive for about 13km involved horrible noises coming from the rear end (the ticking clunk noise) and and feeling insane amounts of heat coming throught he firewall and my heater system. I pulled into the garage and gave it a little rev and there i saw the white looking steamy **** again. which i experience at pretty much the same time last year on this same motor. I've learnt alot since then and reckon i could change the gasket and i probly should as about 4-5months ago i sealed a leak with a chemiweld radiator additive as when my old radiator was in the process of blowing up, it caused a water leake between the head and the block and water was spraying out between the two. Is it worth changing the gasket? I reckon it is since i cannot afford a new motor at the moment. I have a spare head but i need to get it crack tested, and ive taken out the cam so i need to know how to put that back in and align everything up. The thing that daunts me with taking the head off my motor is that I do not know how to get the timing chain off correctly, or set its timing again. And im freaked out that I wont be able to get it running or something stupid will happen, or that ill get it all back together and itll overheat and blow a gasket again. I know how much of a bitch it is to get the manifolds off these motors (L20et) but i'm on holidays for 2 weeks and i have another car to use so i was thinking id give it a go. So i was wondering what you guys think? And was hoping you'd all be willing to advice me on what i need to do. Regards, George

picsssss!

I was just wondering if there were models of the Nissan Skyline like the r30, r31, and models under the r30 and all the rest, were in America? Does anyone own one?

sorry i didnt see below the -----------s in ur first post

Can someone please explain to me how this system works? Here in NZ we dont have any emission controls (yet *gulp*)

I'm hoping someone can, I'll psot this on SAU aswell.

i cant either, must have been taken off from the hosting site for some reason

so..something like this http://www.trademe.co.nz/Business-farming-industry/Building-construction/Tools/Air-tools/auction-43667246.htm ??

I think you'll find they're speaker spacers....

I'm just wondering if anyone can tell me what pedal setup and master clutch cylinder will work on a r30 skyline. Im curious as to if there is any nissan setup that will work, i urgently need something. Thanks. George

I do have all the time in the world....so i wasnt worried about how long it takes. I just dont want to pay a engine shop like $200...but i guess they charge that cause of the pro job they'd do

smartass....

So, anyone else know much about the 05L? I have a spare one for my L20et, i'm working it a bit at the moment. Any suggestions?

Are thye bad heads....? I have one. I want to port it out with my dremel

I also have a spare inlet manifold that I want to work. Suggestions???

I got a dremel for Xmas and have a spare L20et head. I want to port the intake. What do I do? Lol, i know its a basic question but im a absolute novice really. I learn very quick and im technically minded so i reckon i'd be alright at it and would like to give it a go. Regards, George

looking good man!

Wow...*drool* and i thought id seem some awesome Ls but that topped them all. What coulor is your rocker cover? Like if i go into a powdercoating shop what would i tell them i wanted?

Wow. cheers for all the quick and informative replies people. I'm checking out the site now. At present I plan on just using the standard injectors. Although I really do need to upgrade...what should I use? Full specs please

I have a book that covers all that. Ill have a look for it later.

those dowels are a pain in the *** when you're trying to get the head (which has the manifolds and turbo still attached) onto the block which is still in the engine bay of the vehicle...i rememeber stuffing 2 gaskets cause of those dowels

I want to get a aftermarket fuel rail for my L20et, i believe this is the identical setup to the L28et. Unfortuanly here in NZ we cant really get anything for L series motors. Is there somewhere that someone in the USA could direct me to? Thanks

dnt worry about the fact that its a different car and motor. technically its pretty much the same motor.
