i'm letting it warm up for about 5 minutes. i shut the car off and immediately pull the spark plugs, i'm getting thick white, closer to a gray coming out of the 4th cylinder.

my friend came over and did a pressure test and a compression test and everything was fine. but what we did find out is that it's not coolant burning but oil! inside my intake manifold it is completely covered in oil and it's being sucked into the cylinders but it's not burning blue! now i'm looking at the PCV system. maybe the valve is bad, we'll see! any other suggestions???
