Well I got the exhaust all done. Now I can hear i knocking sound coming from the passengers side. I think it is a stuck lifter. So I took it to the builder and he says pull it or his service shop will do it for $1600.00 Ouch and he will dismantle it and find what has went wrong, he says it sounds like a piston to him. But the bad thing I noticed is a leaky Rear Main also. So I am going to have to pull the motor again!!! I have heard to buy a Viton 2 piece seal " Rear Main Seal Kit TIP-RM300 with Permatex Ultra Black RTV Silicone Help don't know what to do. I put a link to a video to show you what it sounded like before I got the exhaust done

Cory, get yourself a long piece of wooden dowel, or perhaps a cut off section of a broom handle (works good due to the rounded end). Press one end into your ear, put the other end on various parts of the engine with it running and making the sound. What you're doing is using it like a stethoscope. This will help you localize where the sound is actually coming from, be it near the rockers or down in the block. That'll tell you something about possible causes.

I'm in the process of a rebuild on my engine and this time I used one of the new 1-piece rear main seals from BOP. Your leak might be the seal, or it also could be the oil pan gasket. I shot some video of installing the BOP 1 piece rear seal that I still need to edit together and post. It's a very good solution to one of the "main" problem areas in Pontiacs.

Bear this old post I was just looking at. Wonder what happen beside him getting screwed by his shop. Maybe he push that broom handle in his ear a little to far. Just kidding buts it's funny how some just disappear. Doug
