I have an oil leak around the filter area. Replaced filter, still leaks and car smells like crap. It is not the filter, it is the housing it screws into or somewhere there. I searched and it sounds like I need a 1/2" allen wrench to torque down the center screw the filter screws onto. What should I torque it too? And I also noticed 2 allen headed plugs that go into the housing. Do I need to torque those down as well? Thanks in advance.
