It could be that the oil relief valve and/or spring are in a sort of
oscillating mode, alowing the oil pressure to vary, but I really know
NUTTING about that little devil...anybody out there care to explain
the oil relief valve theory of operation? Anybody ever change
springs with good results? TIA

Uh-oh. Does anybody know why I get
- 75 psi at cold idle
- 50 psi at hot idle (well, actually 1000 rpm)
- 70 psi at anything above idle on a hot engine
(Bone-stock and mostly original [like, I replaced a few gaskets] '74
18V.)
I can think of two scenarios:
1. I have an incredibly sturdy and well-cared-for engine which, even
though it has 114K on it, is far from needing a rebuild.
2. My gauge is flaky.
(I suppose both could be true. Unlikely, but it could happen.)
Related question: Why does my gauge oscillate between 50 and 70 psi
at hot idle? This only happens maybe 30% of the time, and I haven't
been able to correlate it to anything.
