    It looks from the oil pan, but without wemoving some covers it's going to be complicated to check

    Thanks Chema.RB

    Cleaned everything and I'm pretty certain it must be a leaking crankshaft seal ��

    It is usually the iron block rusting under the the ally front oil seal holder which causes a leak from the main oil drilling, obviously you do the crank seal at the same time just in case, however a leaking crank seal is a sign of the crankcase ventilation system being blocked. Taking off the seal plate is a BIG job though, meaning dropping the upper sump if you are to a avoid pushing silicon sealant into the sump when rebuilding and causing a new leak. IF you use the correct Teflon seal rather than the earlier rubber spring loaded design, remember that the seal and its running face MUST be spotlessly clean and dry with no oil or the new seal will not bed in.
    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.
