Hello, I have recently purchased a 1990 Pontiac turbo grand prix with 130xxx miles on it. I had the top of the motor completely rebuilt (heads,gaskets,seals,ect.) and was running around ten pounds of boost just fine for about 4 months until here recently I noticed a very slight oil leak coming from my back valve cover. I checked my oil consistintely waiting to get in the shop and two days later while running it a little hard it started a decently loud knock. Thankfully I was near home so, I went straight there and shut it down and haven't started it since. The mechanic who worked on it with me before said it was probably a rod knock. So, I'm trying to get any and all advice and suggestions I can get on what to do. This car is rare and my baby so please anything that can help would be great and I'll answer all questions or anything. Thank you for your time.

 

What to do? About rod knock? Tear the motor out, tear it down, and rebuild.
