I got a summit racing oil filter cutter. I've been saving most the filters I've taken off vehicles for the past year or so. I was shocked to see the fram cardboard end caps looked fine. I didn't see any problem with the filter media or endcaps. This model was a ph5 I believe, but the antidrain back valve was worthless. Didn't seal at all. It didn't have a bypass.
Are most regular black rubber antidrain back valves this bad, or are other brands better?
