Thanks, Mark....I  learned something there.   It never occurred to me that
the adjusters themselves could be worn...but now that you've pointed that
out, I can certainly see the possibility...no, even likelyhood...of those
adjusters getting worn or bashed flatter than before in just one
spot...especially on a motor that had a big angle at that junction of
moving parts.

   I've never heard of a WBX motor having 60psi oil pressure at warm idle...
