I have read the horror stories about Fram filters but I never paid much attention until now. My Daughter has an '01 Jeep Cherokee with the 0331 head and we think it is cracked. We put a 160° thermostat in, left the radiator cap off, and drove it 20 miles to my house. When I parked it in my yard I noticed the oil pressure was 0!!! We changed the oil thinking it was contaminated and same thing. So I began checking stuff. I T'd in a mechanical gauge and got the same. Then I removed the gauge and put a barbed fitting with a clear hose to the valve cover filler hole. Ran the engine and got brisk oil flow. No clog there. That is when I spotted the Fram oil filter. I pulled it off and put a new AC filter on. BINGO!!! Oil pressure. So the Fram was the problem, and it wasn't even that old. Unbelievable.
