I changed head gasket to include head gasket kit. Appears that oil remains in engine cooling system (major amount). I'm not sure if it residual or still a problem with the engine head or block. How many flushes should a normal cleaning for the cooling system take after a head gasket change? I've don three so far and nothing has changed in reduction of oil. The color is a light foamy, sticky brown which floats on the water. My gut feeling is the problem is a hidden crack. I do not have any water in the oil. It's a one-way problem.

Thanks,

Chuck
