Re: 16V top end clattering - impending doom?

heavier oil cleared it up for me, well, somewhat.
mobil 1 synthetic 5-50 specifically.
other reason is, of course, oil restriction/pump bad. for a head to make a racket it has to be
multiple valves at once, indicating lower than normal pressure to head.
