I am also having this problem, so I would like to bump it up. My oil was same milky color as mentioned above and it was everywhere in the valve cover and in the oil pan. I did a block leak test, which consisted of putting a special liquid in a tube and putting the tube into the radiator cap opening to see if there were combustion gasses in the cooling system which came up negative. I did a pressure test with the kit pictured above and I seen water dripping somewhere and it slowly leaked pressure. This is where I believe the leak came from:IMAG0899.jpgIMAG0900.jpg
