Hi all,
I have a 440 in my charger and I have always used a mobil one filter (M1-301A) for every oil change and it has worked without a problem. For some reason, this time it would not grab the threads and screw on. I exchanged it thinking that maybe it was a bad filter because the old one still went on fine. Again, the new one would not fit. So I tried a K & N filter (HP-3001) and it did not go on either (won't grab threads). I noticed a little bit of a burr on the first thread so I got a die and ran it back and forth several times and it cleaned the threads up really nice. I tried to put the new filter on again and it still wouldn't go, but the old filter will. When I put the filter on, it only turns about a half turn or 3/4 of a turn until the gasket bottoms out on the housing, and that has always seemed different to me because with other vehicles I always get 3 or 4 turns of the filter before the gasket makes contact. So it is as if I need a filter where the female threads sit higher or almost even with the gasket instead of recessed down.
Super frustrated...any wisdom out there?
Thanks
