bimmerjeeper has an in-depth and highly entertaining thread on replacing the oil filter adapter O-rings. https://www.naxja.org/forum/showthread.php?t=1093343. While you are researching, you should read his O2 sensor change thread also. Don't be a bimmerjeeper, do some research, and enlighten yourself.
Well the adapter came off rather easily, contrary to every other thread I've read lol.
Should this be reinstalled with red, or any loctite?
Never mind, I put the adapter on without any loctite. Apparently I must have used my spare oil filter so now I play the waiting game for a leak test until tomorrow.
