MXTex,
Thanks for taking the time to read through this thread..I'm sure it took a while! I'm not too sure if I'm qualified to answer that since I'm pretty clueless about cars but it does appear to knock at the revolution of the crank.
torqhead,
We have over 40 hours of diagnosis, repair and replace time in this motor since the car was started. There were, what we thought were witness marks on the rockers. I replaced the rockers with 1.65 Crower rockers. When we switched the rockers, we looked at the pushrods and rolled them on a piece of glass. A few of the pushrods wobbled on the glass so we switched out the pushrods with a thicker wall pushrod. I was then told the lifters may not be pumping up. We replaced the lifters (Johnson Hylift) and the same knocking noise was present. When we disconnected the torque converter from the flexplate, that was BEFORE we pulled the motor and identified there was not enough spacing on the windage tray. There were witness marks on the windage tray. I haven't pulled the torque converter from the flex plate since we corrected the spacing. The knocking from the windage tray masked the knocking noise that we are trying to figure out. Here is something interesting though...When I pulled the heads and had them inspected and we got the car on the road again.when I drove it home and parked it in the garage, I turned the car off and right at shut down a noise was heard that I can only explain as if two pieces of metal scrapping and coming to rest.
AG,
If I have to pull this motor again, I think it will be on it's way to Arizona to Paul..hahaha. I do have to say that Paul and Jeff have been awesome and they both have been excellent to deal with. They stand by their product and I would not hesitate to go back and have them build me another motor. Not too many people around like those guys..
torqhead,
The question about the shim exceeds my mechanical abilities and knowledge..hahaha! I have good friends that have been working on Pontiacs for many, many years. I trust them to do the work correctly. I'm assuming it was done correctly but we will find out soon. I agree with what you said about throwing money at parts. I have over $1,000 in parts, fluids, gaskets and Tylenol and have only driven the car less than 200 miles. I think we're getting there though!
