This is very common for a BMW of this age. Whoever changed your valve cover gaskets, should have changed the upper timing cover gaskets at the same time. Parts for the upper timing cover gaskets is only 25.00, & the labor would probably have been an extra 500.00. The lower timing cover gaskets usually do well. Chances are that your alternator o-ring is leaking, & it has been missed. Dealer's usually charge around 700.00 for the labor on this. The o-ring is only around 3.00. If you remove the lower plastic panel, you can inspect the alternator o-ring with a flashlight. Here is a couple of pics.
