I'm trying to help a friend figure out this excessive oil pressure problem with his BBC. He had the motor built about 3 years ago and it's has maybe 40-50 hrs. on it. He claims that at the time of the rebuild he installed a standard pressure/high volume oil pump. The gauge on the dash shown almost 80 psi. when the engine is cold and then drops to to somewhere in the 70's once it warms up. He's getting oil seeping from the oil pan and distributor seal and we're thinking that it's because of the high pressure. We've already tried another sending unit and gauge and nothing changed. Hs engine setup consists of a dual remote oil filter head running 2 Fram HP1's, a 10 quart Hamburger oil pan and an oil cooler that's maybe like 10"-12" long and all the lines are -10 The oil he's running is Valvoline VR 20w50 Any ideas of what may be going on? I seem to think that with 12 quarts total, there isn't really a need for a cooler, but I could be wrong.
