[AT] High oil pressure a bad thing?

[Dean Vinson]

There's a letter to "Mr. Thinker" in the June issue of Green Magazine about
a tractor with high oil pressure.   That caught my attention since my
Farmall M pressure gauge always reads high, and it was the same on the Super
M I had several years ago.  The response from Mr. Thinker talks about how to
adjust the oil pump relief valve to get the pressure back in the normal
range, but doesn't say anything about cleaning or checking or otherwise
servicing anything else in the engine.

So what's the harm of high oil pressure?  If it's not a symptom of clogged
arteries, so to speak, or some other bad thing that ought to be fixed before
it does real damage, what difference does it make if the gauge reads way up
at the high side?
