The system pressure, as read by the guage, depends basically on three things. 1. the condition of the bearings etc/ie resistance to oil flow. 2. the quality of the 'seal; /html/healeys/2010-10/msg00024.html (9,324 bytes)

That fitting is NOT tapped perpendicular to the head. It is frequently cross threaded for that reason and being aluminum is probably ruined.

What I didn't expect was higher hot at idle, because the valve should be fully closed (shimmed spring or not).
