- N.H, U.S.A.
I just had to take a wix off of our Subaru(cross ref'd mazda rx8 application - longer can, thats all). It was weeping oil onto the cat and exhaust - put on a honeywell OEM subaru and NP. When I worked as a mechanic I had three leaky filters; 2 puroleakers/motorcrapt (can-to-base crimp weepage) and one wix (undetermined). I think overtorquing the flat gasket types can deform the gasket and walk it out of its "track" - so I wouldnt go to wild on the filter cap wrench.
