Sounds like your oil is getting through the valve guides rather than the
oil rings, hence good compression & oil pressure (bottom end still OK).
It seems that oil crud buildup in the combustion chambers might be a
problem (too high compression). I would guess it's a good candidate for a
head job and de-coking, but I have no experience with this particular
engine.

Runs great,
looks particularly bad since some SUV clown backed into it.
If you're near Mountain View, CA,
it's the red one with the silver bootlid.
