First the good, I have a mid-time IO-360 with 150hrs since overhaul. This engine had the cam/lifters reground and was pickled for over 12 years in a dry environment. Pulling a jug showed no internal corrosion.
I now have 8 hrs of phase one flight and oil pressure (15w-50) around idle speed is ~35-40psi. At 2700rpm the system is up to 70psi and at 2300rpm around 55-60.
I was expecting more around 75-85psi at 2300 given only 150hrs.
Waiting for 10hrs to do oil analysis but cutting a filter at 1hr (little metal) and 5 hrs (one flake non-magnetic) appears to be good. What is the chance that this is simply the oil relief valve and I just need to add a few washers? Or better yet, is this within expected limits at 150hrs?
