Ignition module ground

This probably does not belong in this post, but I was looking on Ebay for ZR1 engines and found an 89 MY engine with drivetrain and front clip. The date stamp is 88. I noticed the PCV system is different than on my car. I was wondering how similar this motor is compared to my motor and if the rated power output was different. The starting bid is 11K, a bit high IMO but if this motor has some sort of additional collector value since it is an 88 then maybe the price is right.

I have read through this thread with a bit of dispair since I'm currently rebuilding my top end. I pray that I don't run into the problems you have but I have been guided by Mike at EES so I feel quite confident.

In any case, I would be very willing to spend some time with you (ROAD TRIP!) troubleshooting your beast once mine is back on the road. Don't give up on it, but certainly take a break from it. Only bad things come from frustration.

Just know we're out here to back you up. I'm not an expert by any means, but I have a decent troubleshooting mind and have a knack for looking at things from different perspectives. We can and will get your Z back in tip top shape!!!!

Good news

I have finally had a day of free time and have disassembled the LT5 once again. It gets remarkably easier every time. Anyway I have found the culprit. A true mystery, now solved. I dunno how or when it happened. I cant imagine that I did not notice this the last time I assembled the motor. But here it is.....the F F F F'ing hydraulic followers. 17 of the 32 are locked in a fully extended position. I have put a few in a vice and tried to collapse them, but no luck. They will not budge, not even for a hammer. They are somehow solid, and fully extended. I imagin that most or all of them were on the intake side. I did not pay attention due to some extraordinary circumstances. Normally I would label where they come from but I was interrupted, I then turned the head on its back and they all fell out before my brain could think about it. Oh well, but since I had combustion in the intake manifold I assume that most are from the intake and they held the valves open even when riding on the base circle of the cam. How this happened, I do not know. If a piston hit them I would think that they would be stuck in the retracted position. I remember checking them before I put the motor back the first time and they were fine. I always kept them in a zip lock bag with oil.

So, my question to everyone is this: Does anyone have a set of lifters for sale? Does anyone know specifics about what type of audi lifter will work? I have heard A8 but what year? Intake or Exhaust? Does anyone know what has gone wrong with my set?

After consulting with a santeria priestess named Pearla, I have found a solution to my broken lifters. I soaked them in the urine of a virgin overnight and left them in a room full of pennies with silver pieces at the corners.....and what do ya know, they actually do move now. And to think that women dont have a clue. Anyway, the heads are back on and hopefully today will be the last time I need to work on this thing. I will post results.

I remember a thread somewhere, here or at CF or CAC, about lifters. Someone determined that the lifters from the Aurora motor were the same size lifter bore. I don't know if this is of any use to your situation.

Good luck with the motor!
