Oil leaks
 

I have a 1990 760 gle with the b280f with an oil leak on the front passenger cylinder head front cover
. Any ideas what its is called,
how to get to it.

Well, that's a V6 and as such it has valve covers gaskets which are the most common source of leaks. Sorry, I am not into these motors, few are, but this would be a good place to start...
