I have a strange problem with my 96 vr6 golf. The oil is mixing with coolant but no coolant is finding its way into the engine? I ran a compression test which had all cylinders holding same compression, the head has been skimmed and has a brand new head gasket. It was only on for about 10 mins and all the oil had gone into the coolant. Could this be to do with the oil cooler? Or what else could cause this? Thanks BRian
