1990 325 with water in the left side trunk well under the jack. When it rains it gets from 1/4 to 1/2 inch of standing water in the left side only. Already changed the tail light gasket on that side as well as the antenna grommet. Can't see any "tracks" where the leak has left any residue. The trunk seal is original and does have some worn/torn places on the left side, but again, no residue or evidence of any leak. Changing the two gaskets has seems to slow it down and it's not as severe but it's still there. My next move is the trunk seal, any thoughts on what else it could be?
