Hmmm, impressive, I like that. I don't know if I would have made one out of wood like that, but it looks good. I'd use it.

Not sure how in the hell this happened, but I have nice little smiley faces in each of my pistons from the exhaust valves. Doesn't look bad, the valves are probably bent although they look fine and the indents in the pistons are only about .020" deep or less. I can't figure it out, but it had to be from when I had the car running as the ones where the cam lobes from the schneider cam didn't wear out are shiny indicating they were hitting the whole time. Now I did notice where I had marked the chain last time wasn't lining up this time, it was on the opposite side of the cam gear from the #1 marker, but everything else was lined up though. Piston is at TDC, both #1 and #2 lobes were up and the crank pulley mark was at 0 just like last time. Is it possible my chain might have skipped a few teeth during the initial startup when the pump was dry? No oil pressure would cause the tensioner to not put tension on the chain. In either case the valves I pulled out were .015" shorter than the valves from my P90 and .080" shorter than the stainless steel valves I bought for my performance N series head I was hoping to build one day... My head hurts...

Ummm, double post? Didn't I just see this in the Body thread?

You lucky a$$ SOB.

Just replace the fuse with one the same rating as you pulled out. Sounds like you took a power spike and your power regulator might be suspect. In any case there is nothing any of us can do or tell you from here other than, check your wiring for loose, corroded or worn connections. Good luck.

Replace the fuse with what ever came out and check your battery and cables. Make sure the battery is secure so it can't slide around. Also check your fuseable links.

My best friend who's serving in Iraq right now made this up and I had to post it. He wrote it down for me so I could let all of the Z world share in his deity like insight...I love it...lol Yea though I walk through the valley of rice, I will fear no turbo, For displacement is with me, My bore and my stroke they comfort me Surely horsepower and torque shall follow me all throughout the rpms And I shall have bragging rights for all time. Amen Hahahaha I love it.

Thanks BRAAP.

Phil, I must say you are a trip. Makes me wish I still lived in Texas.

You know, I didn't even think about nose wear. The Schneider cam lobes that wore down only wore on the nose of the lobe. Guess I need to spend the money on the head set again and pull the whole thing apart...again.

OK, I am at my wits end here trying to figure this one out. I dug through the garage and found the P90 valves. I verified it by setting one of them next to my N series stainless valves and it was notably shorter. So, if the P90 valves are out in the garage that means the valves in the N42 are the ones that are suppose to be in there. Which makes sense as I sent the head to the machinist with the valves springs and valves in it and he says he kept the valves with the head the whole time he was working on it and that I never sent any valves with the P90, which obviously is true as the valves are sitting in the garage right now. What now? I'm at a loss here, I have no clue what the problem could be now. I measured the height of the valve springs tonight and compared them with a N47 and the N42 spring height is lower by about .080". So that proves it, the valves are sitting lower in the head. The machinist didn't put new seats in, he just lapped the valves and ground the seats to match. HELP!!!!

Anyone? Will the shorter valves effect my engine? Will it damage it at all?

Search the forums for the answers to those questions. You may also want to get a copy of the Factory Service Manual from http://carfiche.com

Sounds like you probably have a vacuum leak or a bad head temp sensor.

Ok it all makes sense now. Still not sure "how" but I'm convinced now that I have P90 valves in my N42 head. I found the numbers on how much shorter the P90 valves are from the N42 valves, 2mm. As we all know (I'm sure) 2mm is roughly .080". I have a stock cam in my engine now and the stock .120" lash pads are about .080" too short...I wonder...What kind of problems could I be looking at here? Increased seat pressure causing the valves to beat the hell out of the brass seats?

I just thought about something. Is it possible to fit P90 valves in a N42 head? I know the P90 valves are shorter than the N series valves and my machinist had both my P90 and my N42 in his shop at the same time. I'm starting to wonder if he mixed the valves by mistake and that's why my lash pads seem to be measuring out thicker.

Yes I know how to check my wipe pattern. I started with stock pads, set the clearance by the cold settings in the FSM, .007 int .009 exh, turn engine over one rotation pull the rocker and check wipe pattern. I used a sharpie marker to color the pad on the rocker. It came out really low with stock so I put in the performance pads that were .160" and they were really low on the pad so I added a small washer that measured .035 and it put the wipe a hair on the pivot side of the pad if that. So .160" + .035" = .195". Pads go in .010" measurements and .195" was just slightly low anyway (not low enough to make a difference though) so .200" is where it's at.

I understand that, unfortunately I can't find anything wrong... Compression is good, all the valve springs are the same height, all the lash pad measurements from all the valves give me the same size, .200", and I don't get it. Aside from the performance springs from MSA, the valve grind and the head decked, every thing is stock.

My pads aren't too thick, they're too thin. I have .160" pads and it looks like I need .200".

That's why we still have the original kits...

The ZXR was just a trim and pin stripe kit with wheel covers and a spoiler, nothing really special. Just the like the 77 ZAP models, no real value, but nice to see an original just for fun.

Yeah I was trying to think of ways to do it without drawing more attention to his final goal and pissing them off more.

What will they think of next...Gotta love those guys.

Good question. I suppose the easiest way would be to go to the clerk of courts and check for previous grievances and/or court cases involving the shop, then inquire on which attorney they used. More then likely they use the same guy every time.

Sounds like the shops around here. You will most likely need a lawyer to get any further with this. Best bet, find out who his lawyer is and go talk to him about the problem. Then he can't even use his own attorney for the case.
