RE:Oil Pressure
After all this talk about oil pressure I took the Stag for a run on the
weekend and recorded the following figures at the end of it. This is from
a new gauge I have recently had made up and I am assured by the company
that made it that it was carefully calibrated. I must put my trust in them
on this aspect.
RPM lbs/sqin
600 16
1000 25
1500 34
2000 37
2500 39
3000 42
3500 44
4000 46
I have every reason to believe the oil pump is original and has never been
off the engine before. I base this on recently having disassembled the
pump to replace the O rings and found the old O rings were so brittle they
crumbled as I took them out, a sign I believe of 20 year old rubber. This
also solved a bad oil leak.
