As I was torquing down the bolts on the oil filter cover, one didnt seem to be getting tight. SO i took it out and tried again. Well then the bolt broke leaving half in the case. I was able to easily get it out with a small pair of needle nose(showing how loose it was). I took a light to the thread on the case and it looks fine. SO my question is do you think that the threads are stripped, or would it not tighten as a result of the broken bolt? I am going to get a new bolt tomorrow but am worried I am going to half to helicoil the case. i am hoping that something was just wrong with the bolt and thread are fine.
