I have an 05 Polaris Sportsman 800 efi. I noticed that it had started leaking oil around the oil filter. Picked up new polaris filter and changed it. After cranking it, noticed it was still leaking and gasket was sticking out from filter on top. Took filter back off (again) fixed gasket back in grove of still new filter and reinstalled. Cranked it again and as it was idling, it was ok. When I gave it gas the gasket around filter " blew " again. After research, I changed the oil pressure relief valve and this seemed to work. Went for ONE ride and it did ok until I got it home. I unloaded bike to put it up and oil gasket " blew " again. Anyone have any ideas or suggestions for fix. Thanks from Ms.
