Uh Oh...funny noise from valve cover.

I just bought a 93 325is e36. The car runs nice, but strange noise coming
from valve cover. Using a stethescope, it sounds as if something is rattling
around in there. The car drives well otherwise, but this is the type of thing
that seems like it can go south very quickly, and I dont want that to happen.
By the way, as much as I liked my 92 525 (e34),(Really nice handling cars), the
e36's are much sportier and fun to drive in a 5 speed. Im in love with this car
even more than my last. Thanks for your time. :)

You know it's funny you posted this, I've just noticed the same on my '94. Still looking for a good shop around where I live to have the Inspection II service done, and I was gonna have the shop check it out. I've noticed on mine that its intermitent, and more noticeable with the A/C running. Any help would be great

Thanks!
