Engine was swapped because the old one was very tired. From speaking to Steve on the phone the header tank was empty of the 30 secs of running hence he couldnt see if it had mixed with the coolant, I dont think he has dropped the coolant from the radiator yet. He has drained the oil and as he said above its mixed with allot of coolant. I cant see it being the headgasket as it ran fine in the old car drove it the night before we took it out, any other ideas?
