So here's the deal, after my initial break in on the bike. I switched and went to a stainless (CompFlo) oil filter. Ever since, I've had this annoying little oil leak comming from my cap (I left the original on). The upper right O ring did break when I originally removed the cap. I've since replace it twice with 2 different sized O rings, but no dice. Do I need to purchase the CompFlo cap as well? Or keep playing around with O rings till I get one that works?
