Problem with Crower valvetrain
Hi,
I've a problem with Crower springs and retainers in the H22A7 (TypeS) head. Actually nothing is wrong with springs as the compress enough to lock them in place. The problem are retainers. I can't set a proper valve lash in 10-11 valves. After the inspection it appeared that the rocker arm was hitting/lean against the retainer before the adjusting screw even approached the valve.
Did anyone experience such a problem? What to do with that?

That has been a well documented problem with the crower valvetrain from day 1. It's not your fault man. Most people just make a relief in the rocker arms to clear the retainer.

Re: Problem with Crower valvetrain
Where can I find more info on this? Thanks a lot.
Edit: nvm I found it. Anyway thanks again for enlightment.
I don't like the grinding rocker arms idea. We're going back to OE retainers and stiffer springs.
