I sent this in an email to a friend, but it seemed wise enough to share with the world...
Whilst changing your oil, some advice:
Do not, under any circumstances, try to unscrew the oil pan plug by shoving it in the incorrect direction. The following events might make your life more difficult and -- indeed -- may even cause a certain level of stress and even irritation.
See, BMW intentionally designed the plug to be weak -- so that, when idiots decide to loosen by tightening, the screw will not strip the oil pan threads, thereby causing even greater damage. What occurs, in fact, is the breaking of the plug snap in half, leaving the head in the hand of the stupid head, and the rest in the body of the oil pan.
What’s good is that the oil pan isn’t shot. Thanks, BMW, for protecting me from myself. What’s bad is that I’ll have to drop the oil pan in order to pull the rest of the plug out, because for some odd reason engines do not enjoy sucking up large chunks of metal.
Update. Dateline: 11:22PM.
I may not need to drop the oil pan; it seems that the plug is hollow, meaning that the remainder is still screwed into the pan. There are tools designed to remove nuts that have lost their heads (a vaguely interesting remark, I’m afraid) called (alas!) Easy-Outs. With any luck, I’ll remove what remains of the nut, and screw... ah, this paragraph is fraught with double-meaning, and so I will stop while I am ahead. Summary: I’ll remove the remainder and install a new plug, and all will rejoice.
Also, Hellhounds are real. Tremble in terror. I do.
Update:
It works. End red alert. Everyone’s kung-foo partying.
