Had the 90 degree adaptor off the engine multiple times. Finally went to two wagon wheel gaskets for where it mounts to the engine and a crush gasket at the bolt. Seemed to work for a while then it started leaking perfusely. Is there something I'am missing? I've tried everything I can think of. All mating surfaces are clean and as they are cast iron I don't think they could be warped. Is there a pressure valve in the housing that could be failing and causing increased pressure that oil blows by the gaskets. Hand tightened so as not to cross thread or have mating surfaces not come together before torquing to about 35 ft lbs. Kind of running out of ideas, tryed silicone, gasket maker everything seems to leak. Anyone run into a similiar problem?
