Ok, I've been chasing my tail with this false knock thing on my car. After the new engine went in I've been getting some crazy readings even if you rev the car up in park.
Decided to pull the intake and check the lifter preload. Looked like it had way too much, so I decided to shim the rocker shafts. put .060" in first and the push rod had a little lash. So I went with a .030" shim. After back together cranked it up and a noise was very noticable and was the rockers hitting the valve cover but just on a couple cylinders.
I know I need to remedy this problem, but has anyone else had it? I don't know whether to take the shaft shims out and keep looking for the problem or if it could have been hitting the whole time just not as bad.
I guess I could stack 2 valve cover gaskets and then try it. What do you think?
