I rebuilt a 302 from my 91 5.0 which had bent valves and pushrods, broken block and crank, but doing it on a budget, I re-used what I could, my concern is the factory hyd. roller lifters and the rocker arms, not thinking about it at the time(should have just bought a crate motor looking at it now).
Now the motor has some "ticks" in the top end and I cannot tell the difference between rocker arm and lifter noise. It runs fine, just the ticking is getting to me. Is there a way of telling what piece of valvetrain is making the noise, short of replacing the valvetrain? If I pull the lifters is there a way to visually or otherwise confirm if they are indeed collapsed?
The tick is barely noticeable at an idle, but as rpm's increase the ticks get louder.(can only hear the ticks with the hood open standing beside the engine but it doesnt seem to just come from one place on the top end, it sounds like it is a few lifters or rockers).
I was informed recently it could be collapsed Lifters or damaged rockers, they are the crane/ford aluminum 1.7 ped. mount rockers, I can not see any visible damage to them, and I just retorqued them last night to make sure they didnt loosen off, 3/4 turn to 20lbs, let pressure off the lifters for 5 min before torquing,
