I'm looking for ideas as to why the oil pressure on my engine is HIGH.
XP-360, about 500 hours. Runs perfectly, low oil consumption, all compression 78 or better (cold!). It does sling some oil out around the prop seal, possibly due to the high OP.
Its always been a little high on this engine, meaning 80-85 in cruise. I've noticed its recently crept up to 90 and occasionally bounces a little higher than that.
Just did the CI all filters and screens clear, no issues with oil temp or anything else.
The oil pressure relief valve is of the adjustable type and is cranked way the heck out.
