Don't mean to scare you but I used to have an '86 535i and was told by
several knowledgeable BMW enthusiasts that the engine was virtually
indestructible. Well, when I bought it (with about 200K miles) it had a
bad leak from the cat which I had rewelded... then I found that I had a
tapping noise from the engine... well next time I had a free weekend I
took it to my parents' house (about 150 miles away) and reset the valve
clearances... noise still there... that's when I started to get
worried. On the way back the oil light started flickering when I
stopped for tollbooths etc. D'OH! Next time I started the car it
immediately spun a rod bearing. Not good. I'd maybe put 2K miles on
the car and I had to spend as much as I paid for the car to have a
junkyard motor put in it.

IOW, get it checked out soon...
