this is a tick not a knock, and those connecting rod bolts are really tight!, in fact, id use a little rtv or thread locker to ensure that would never happen, since the studs are replaceable.



NOW I NOTICED THE PRICE FOR A SET OF ROLLER LIFTERS ARE EXPENSIVE ! I NEED SOME GOOD ONE. I might as well just buy a cam roller llifter combo! lol

I G Joe

probably a valve

have you checked the header gaskets?

or the noise is not coming from there?

ACE

check your lifters and your pushrods, maybe your pushrod fell out of hte groove or is too long?

the hydraulic lifter in the picture you are looking at is the cause and is the culprit

HOWEVER, NO ONE TOLD ME YOU HAVE TO TEAR THE ENTIRE ENGINE DOWN TO GET TO 4 OF THE LIFTERS!

WELL I JUST STARTED THE TEARDOWN[:@] im really pissed, but id do this car in a heartbeat campared to those damn OLDER GM BODIES, THEY SUCK!!!!!!!!!

well , the heads and brackets attached has to come off just to remove the four lifters, the ones at the very end. just tempting to put a bigger motor in lol

AS YOU CAN SEE THERE ARE BITS OF CARBON, VERY HARD , dirt and grime that had been the result of these lifters being original and original owner never changing the oil.

The ones i could get to are soaking in parts solvent(12). SO CHANGE UR OIL and I hope this quiets, now, this can cause power loss( bad roller lifters)

im just not sure if I should be able to push on the lifters up and down with my finger( or not) to indicate worn bores??????????????
ANYONE???????? NOE OF EM WILL PUSH DOWN WITH FINGER FORCE
