I have no experience with your engine but usually there is a single

see what happens.

He says his motor develops something like 50PSI at higher rpms, so it
doesn't sound like the pressure relief valve(s). Maybe the pump is
worn, perhaps the main bearings are going, perhaps the ambient
temperatures are higher than he's used to and that's thinning the oil
some,,, maybe a bit of all of the above?



If the pressure is in the ballpark and oil
consumption does not go up then I'd leave it alone - at least for now.


Fair enough.
