Any ideas on this guys? I've changed my head gasket using new OE head bolts and correct torque/sequence. There was coolant in the oil beforehand (which prompted the gasket change) but now it's back there in even greater quantities than before (about 0.5L after an hours driving).

The engine never overheated, so the head shouldn't be warped, and I checked for this anyway before re-installing.

Could there be any other reason for there being coolant on the engine oil?? A corroded water channel perhaps??

Many thanks,
