Hey, I finally got my Supra on the road but I am concerned that im leaking compression into the cooling system why I say this is when I start the motor up I get pressure straight up in the radiator. I am not leaking water into the oil or viceversa. I am using a Copper head gasket and O-ringed block. Why is this happening, the only thing I can think of is that there could be a small gap between the two ends of a or all of the O-rings. Ill be pressure testing each cyclinder tomorrow but I just want any suggestions regarding my problem.
