    I don't think adjusting your valves will solve a rocker hitting problem.

    Are these stock rockers/springs?

    If you are getting a valve lash tap... then adjustment is necessary.

    ***Assuming this is a hydraulic flat tappet cam/lifter.

    You WILL GET OIL EVERYEHWERE!!! Even if you use the rocker clips... /forums/images/icons/crazy.gif

    With the engine idling... turn the rocker loose until it taps loudly (assuming it is not doing this already). Turn it tight until it stops tapping.. Now turn it (some say 1/4) 1/2 turn (per HAYNES manual) tighter. That one is done. Only 15 more to go.

    You don't need to get oil everywhere. Here's what you do:

    Get an old set of valve covers and cut the top out of them so you can have access to the nuts. Mount them in place and there you have it. Do your adjusting, then replace with your good valve covers.
