Mopar Oil Filters Any Good?
All the above filters bypass a significant amount of oil that doesn't get filtered during normal use. The only filter I know of that doesn't ever bypass any oil is from Jomar.
Jomar filters saved my bottom end from damage with I blew out all the needle bearings in my T&D rockers due to improper valve train geometry.
This damage happened over time, and I never found an intact needle bearing in the pan. There were parts of them in the heads. It was strange, and took Dwayne Porter to figure out what caused it. None of the debris made it back into the bottom end. That's the Jomar 100% No Bypass difference.
