I've got an minor leak from the seal on the spin on oil filter, which is from too high an oil pressure when the engine is cold (100psi....it settles down to a healthy 50 when warm though).
The engine had a saab uprated oil pump fitted some time ago and I was thinking that changing the oil pressure relief spring would help. Am I heading in completely the wrong direction - should I just bite the bullet and swop the whole pump assembly or will this work?
(i've already had new o rings fitted to the spin on oil filter adapter, the leak comes from the gasket on the filter and i've checked everything is properly fitted properly.)
