Has anyone had problems with the bottom bolt on their oil filter cover? Its the bolt with the alan wrench head. I think mine is on the verge of stripping about 1/2-2/3 the way in to the case. The first 6-7 turns are fine and then it starts binding. I cut the bolt down so it would only go in the case about 6-7 turns. There is enough meat on the threads to avoid addition and potential stripping. Does anyone have a solution? I bought a tap but am a little reluctant to start tapping. HELP!!!
