Hi i will try to make the story short, i replace cylinder heads, cam and lifters, pushrods, rockers and distributor.

I am having an issue with a noise try to change timing (ping) problem isn't there. I have reajust the lifters (hydraulic) cold way (no mess) and hot enine running ( i have read the article in the forum). I had to tight a lot 2 turn more and noise was gone. Next morning car didn'T start because of valve staying open, back up nut 1/4 turn and check compression in all cylinder 150 psi but noise is back. Is it possible that the lifters are defective ( not sealing properly) Is there a way to check them in the car or i have to take everything apart.


thank you fo your help

When you changed the heads did you check your pushrod length? If everything else was done correctly I would guess that they are too short. Check with the company that makes the heads for their recommendation on pushrod length.

The noise doesn't seem to change with RPM, if I am hearing what you are hearing.

Maybe a rocker is hitting the a valve cover somewhere? Could always check them for any damage. If no damage is seen you could always start the car a run it for few seconds while the covers are off. It would be easier to pinpoint the noise if its from the valvetrain.

Exhaust Gasket leak sounds like a Tappet noise, Fuel Pump Arm or rod too short. Ensure that Bolt on the Front of the Block Psgr Side isn't too long and interfering with the Fuel Pump Rod. Cracked Flex Plate if running an Automatic.

Loose dust shield hitting the back of the flywheel/flexplate?

I have to agree it sounds more rotational than reciprocal.

I could be in left field but that sounds more like something rotating and self clearancing on something else (like on a lathe) than valvetrain to me. Maybe take a look at all your pulleys/timing pointer etc.
I agree. It's small and spinning. Check inside the disti, maybe?

Can you pull the valve covers and check for the noise with the engine running with a hose or stethoscope? If you do find the noise is actually coming from the valve train you need to isolate which valve rocker it is coming from and check the lifter. From your "mess" description it sounds like you are getting oil to all of the rockers. Did you verify clearance between the valve and piston when you installed the new heads?

Hi ,i have found a defective roller rocker, but my noise is not there,i have install all my regular rocker and noise is still there. I have put back the old distributor same thing. The car his automatic but there are no cover on it. I have thight the headers and exhaust flange. The clearance where check before heads where on and to select proper cam. I am going to look at at the fuel pump rod and at the flex plate today. :clonk::angry:

thank you
