Hey guys

Alright, I got a 83 camaro, I kno it never came with a 350 but I "was told" that its a 350 out of 79z28. Ran the numbers it was a 350, anyway I have a knockin noise coming from a couple of my lifters, I tighten them up, the noise went away until I started reving up the car, the knock came back. Should I tighten them down more or what???

thanks guys

probly wouldnt be a bad idea to adjust all your rockers. the "easy" messy way to adjust them is to do it with the engine running. just loosen one up till it just starts to tick, and then tighten it back up 3/4 to a full turn.
as far as wiping a lobe, check to see if all your rockers are moving while the engine is running

Yea I was doin that. Noise went away, startin clean up the car reving it up and stuff all of a sudden noise came back. I was Like ***...so I tighten it up again and started hearing ******* on the driverside so I tightened those up, as soon as i was gettin ready to leave the damn thing started to knock again.

the engine has some miles on, not sure if it was rebuilt, but i doubt it. I kno it doesnt have a stock cam cause when i try and set the timing from the book the car runs like *******.

Doc here, :pimp:

That would be a clue that the cam was going away..can't time it and clatter after adjustment.

Doc :pimp:
