I tried gasoline in a big plastic bag - but I think I need something mechanical to loosen it a bit. I will keep trying things - but ideas are always welcome because I want to try to do this before heading back to the dealer for the o ring.

Yikes! If the o-ring fits INSIDE the top of the oil pan housing, my garden-hose washer likely won't go inside (it will sit on top). That will change things!

Called Stevenscreek BMW (they're open 'till 5pm). They have the o-ring (19,5x30 in stock, P/N 11431740045, $3.83); but they don't have the dipstick guide itself ($117).

Also, I broke the plastic clip on the side of the dipstick guide - but I don't see a part number for it (#17 below). In fact, I don't even see a non-ENDED part number for the oil dipstick guide tube.

But, the most important question is what happens (now that my dipstick is clogged) if I put it back?
