Ok I have one thing to say about Fram oil filters, DO NOT USE THEM!!!!!!!!!
Let me explain, we own a 2001 Jeep Wrangler that has been running fine since new, we bought it from Priority Toyota 2 years ago for $6000, it had 63k on it, ran fine the first few months, then it started a little tiny bit of valve clatter between 1st and 2nd, I thought nothing of it, then it stated getting worse, last month i changed the lifters, cam shaft and push rods due to abnormal wear, thinking it was something majorly wrong i hooked up a direct pressure gage to the block, I got 45psig @700rpm nominal w/195deg temp. that is normal, what isn't normal is the Fram oil filter for the past year has been letting all the oil drain from the top of the engine back into the oil pan, due to a cheaply designed and built anti drain back valve.
Now I have the Jeep sitting on the back porch with the hood all the way open so I can change engines, all because I used what I thought was a good oil filter.
Basically this Fram filter has been causing a dry start every time the engine was started, causing premature wear on everything from the brand new lifters (now abnormally worn) since there is no oil in engine until the pump pumps it out of the pan into the engine. I now recomend ANYTHING except Fram products.
