oil leak around the top of engine on 2001 BMW 330i

I see oil on ground and around the top of engine

you have a leaking valve cover gasket, which is on top.
you probably also have a leaking oil filter housing gasket, which is closer to the bottom. these are very common leaks and happen to ALL six cylinder BMW's.
I second overby's on those gaskets. They are common. Get your PCV system checked also.
