Ah yes, the muddy, whipped, milk chocolate looking stuff. That's the famous oil and water froth. That usually comes from a crankcase being filled with coolant, raising the liquid level inside till it reaches the crank-- that's how you get the "whipped mousse" look to the oil. Judging by the amount of coolant (1liter) you drained from the crankcase, I'd suspect a fairly good internal leak. Oil cooler perhaps? > > #1 was FULL of coolant, #1? Like the #1 cylinder? > strangly, the collant color is perfect with no trace > of oil.... I've had 2 cars come down with "whipped oil/coolant mix" in my life, and the oil never got into the cooling system. Usually the cooling system is operating at a higher pressure than the oil system in the places where they are in close proximity, so it stands to reason that you'd only see water in the oil and not vice cersa. -- John Bange '90 Vanagon "Keine Bange, wir holen die Zange!"
