Figured out my pressure problems for the most part. I verifed oil pressure
with a mechanical gague and with 10W40 oil I am seeing approx 15 psi at
warmed up idle, 30 psi at 2k rpm and 60 psi at 4k rpm.
I still am seeing low oil pressure at startup and when i pull the temp
sensor under the relief valve its sticking against the seat. It will free
up if I increas rpms briefly at startup but thats not good for the motor
overall. I have already tried cleaning the valve body and switched it for
another one I had as well. I also tried cleaning the seat with a rag soaked
with carb cleaner to try and break up any varnish. Couldnt tell how
sucessful I might have been though, and i'll check it again in a while once
it has cooled to see if its still sticking.
Anyone got any ideas besides changing the oil pump which is something I
*REALLY* dont want to do.
