Wondering if anybody has any data from a reputable source that might help answer this question for me... Fighting with a dealer that changed the oil on a Jeep Patriot, and then about 3000 miles later the oil filter came loose, the oil was pumped out and the engine seized. (This was a different dealership that said that the loss of oil was due to the filter coming loose and the oil being evacuated - pumped out - quickly.)
I have heard some say that if it does not come loose right away, it won't because it gets tighter as it heats up. I have heard others say that if it was not tightened properly, it can come loose at any time.
There was no double-gasketing or any visible defect in the filter either.
In my thinking, the latter could be true - if the manufacturer calls for 10 ft-lb of torque on the filter and the person used 9, then changes in the air temperature when the vehicle sits idle could cause it to loosen.
Does anybody recall seeing an article in a magazine or trade journal that can shed some light on this subject? If the filter is put on properly and the filter is not defective, what else can cause it to come loose?
Thanks much for your time and input.
