Yeah, I preoil the seal and fill it with oil. This is the first filter I have had this happen on ever, so I seem to suspect that my oil filter wrench sucks, and that the indentations in the pureone filter are too small. I put on another wix filter since I've had no problems with them. Also, after changing my oil to Royal Purple and removing my A/C belt, it seems that accelerating from 50 in 3rd to 4th gear is quite a bit faster. I went to the track last night, but the stupid hicks don't know how to waterproof the lights, O I waited 4hrs to hear that is was canceled.
