Doc here,

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

lookatme how far down did you tighten them ? it could be a collapsed lifter. .........maybe. if its a collapsed lifter, you might try loosening up your rockers gradually and see if they will pump back up before you retighten them.

camarodude87 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.

lookatme 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

Knocking Comeing from my 350

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
Ray
