Hi all, Drained this out of my mates CBR6 yesterday, boiled up and drank 1 1/2 litres of oil - the remaining oil is clean, the coolant has turned into a thick tan milkshake mix of coolant and oil... Head gasket blown? Could be the water-cooled oil cooler around the oil filter?? Hectichectic...
Probably head gasket? but I had a KTM on which the water pump housing corroded through and the coolant ended up in the crankcase - wondered why it wouldn't turn over...
