I am hoping someone might have a idea. The remote spin-on oil filter leaks at the mounting flange. After 50 hours of use the split line leaks, I have tried 3 or 4 different gaskets and different thicknesses. I have tried sealant with the gaskets and it still leaks at 50 hours. I don't have a differential pressure gauge across the filter so I do not know if it is getting dirty enough to cause excessive pressure. The engine pressure is 40-60 psi. The contact area is only a 1/4 inch where it leaks. Any thoughts? I am using a NAPA 1806 filter.
