    Symptoms of valves needing adjustment on an S54??

    I'm developing a hypothesis that I'll share later. Minor and Major symptoms, if you know..

    Thanks,

    John

    My out-of-the-blue thoughts...

    Well, I've got an S52 (no issues - hydraulic).

    But, with the S54's solid lifters...
    If the clearances are too wide, there can be noise - you know, clickety-clack, somewhat irregularly if they're not all even. Possibly somewhat reduced power at high rpms. Possibly higher wear on components.

    As for too tight clearances, I just rebuilt the head on my e30 and did the old eccentric-cam rocker adjustments.
    Symptoms there were a *very* irregular idle and *no* valve tapping noises. Valves were too tight from the machine shop (<.008"). Adjusted to .012 all around and idle is now butter smooth.

    hope this helps. i know it's a bit off-mark for you, given engine differences.
