OK, I have a big problem. I am doing a chain replacement and when I pulled the intake it is full of milky crude, it is all over the EGR tubes,intake manifold,throttle body,and air intake tubes! when I pulled the valve covers they have the same crude all over them too!! what is this and how do i fix it? the motor ran great. very little coolant came out of the radiator when I drained it. I wonder if the over flow tank was blowing coolant into the intake.?
