Engine knock after head install

[Smitty]

Well i put a set of heads on my car about a month and a half ago. Every thing was all good for about two weeks. then all of a sudden i noticed that why oil pressure was droping serverly while the car was ideling. under load was ok just at idel. Then a feww days later it developed a loud knock.



So i took the heads of again and checked everything out. Everything was just fine. so i finished everything the other day and the car is still knockin and i dont know what to do. It sounds like there is something wrong with the oiling system, ie: oil pump . Any suggestion or any buddy know of any good shops in the chicago-land suburbs.

please help me out.

If the heads are still up, check all the pistons. Crank it over with a ratchet and when a piston is heading down, push on it and see if it budges.

This was the problem with mine when I got a real loud knock. Pushed on the piston (cylinder 1) and it went down a little bit...

Its probally not your top end, its mostlikely your number 2 rod bearing...

Ouch, if it is, good luck. I haven't driven my car in a month because of rod bearing number 1.
