I say this many times but to be sure, pressure wash under the car, check oil dipstick in the morning when engine cold. Top it of if not max, then a week later recheck the level. if you loosing oil time to check for leak, this V8 has many problems, valve-cover, upper timing chain cover, oil filter housing, hope not main seal where the trans has to come out which means mucho dollaro/peso.

ok cleaned up the engine (bottom) so quite clean
but have been looking at this for the last 6 hours and all the post from varios bmw sources.
Quite a few have said could be a valve cover gasket seals dripping down and there is a picture of some one elses and looks very similar to what i am seeing.
But
i have tried getting under the car to see if leaking from there but a no way of seeing into that area directly from the top or the bottom that i can see as covered by a large pan cover going from one side of the car to the other protecting the engine (can i remove this will i get a better view then ?)
thanks

You can remove the belly pan(the black plastic), there are about 13 screws 8mm and 10mm hex to see better but it's still kinda hard to pinpoint the oil leak.
I'll use brake cleaner if I were you, with the belly pan off, spray from the engine bay outside the garage. be careful it's rather strong solvent.

Almost always you'll need valve-cover gasket, I just did mine. To check remove the spark-plugs closest to firewall if you see oil in the plug well you need to replace the valve-cover gasket for sure.
Other leak I am not worry about unless you are loosing 1 quart in 2 weeks or less, with leaky VC-gasket though it'll foul your plug then you get misfire which is not good.

I am also jumping in as I have a similar issue with a bit of oil in the plug wells. Is it hard to replace the valve cover gaskets and are there any threads that detail this?
