I have a 99 R1100RT with an aftermarket oil filer cap installed by PO. The cap is the metal type requiring an allen wrench for installation/removal. My problem is that when I put it back on the other day after topping off the oil, I tightened it to the point where the whole assembly now just turns (by whole assembly I mean both the cap and the insert liner that it screws into).
So I am looking for suggestions on how best to get it out. I am thinking it may be best to just pry it up with a screwdriver, but wanted to see if there was a better or less destructive approach. Thanks..
