With a leakdown you will need to listen to tell where the leakage is. Through oil filler hole is rings, through intake manifold is intake valve, exhaust is exhaust valve or around head gasket is head gasket.

Larrybible,
your advices are always very helpfull.
On my 260E 1988 Euro, +/- 400 000km, I see very often oil in the intake manifold below the throttle flap and (keeping the Air Mass Flowmeter diphragme wide open).
Does it mean that I have a worn intake valve? even if I do not feel any loss of power nor excess fuel consumption.
just some oil to be refilled(' 2 liters per 10 000 km ( which sounds normal to me).

Thanks for your advice
