2lt 16v twin. 1994.broke cam belt 16000 ago, engine started burning oil after 10000 (warranty out) approx 1lt/300mls.filled up expansion tank and water dissapeared into oil sump! rapidly.have removed head and clocked, all ok.pressure test next.has anyone experienced this problem!!!!
Think there is a post similair to this one. May be the head gasket. Is there an emulsion around the inside of the oil filler neck or cap ???
If you're sure the water is dropping into the oil and not evaporating through a leak, then this may well be the problem.
