My A-65 had the lower half redone.
At operating temp. and at idle, the oil pressure is certainly below
15PSI and may be below 10.
I asked the company that did the work and they replied "we don't worry
about low pressure at idle".
Continental says a minimum of 10PSI.
I'll get my A&P to put a real pressure gauge on to see what the
pressure is.
In your experience, does idle typically produce less than 15PSI or am
I looking at a problem?
