When I look at it, this what I see.
Nothing is too good for my Baby. After almost 20 years at my service, it deserves it :-)
But what counts is the puddle of oil that has been slowly dripping in my parking spot for the past 3 years. The fact that all of a sudden it lost 1 liter of oil, which indicates that oil is being spewing out of the engine at speed. To corroborate, the general area behind the engine, PS, is all caked with oil and dust. Plus the UV dye line that now shows very clearly.
I am not equipped to open up the engine. But what I see is consistent with the Bentley :-)
