Black Build-Up on Intake Manifold/Water Pump
I am getting a black build-up on the front of my intake manifold and around water pump. Turns into a real, thick grease. Anyone know what it is, or what causes it?
Though maybe a seal was blown and it was a small oil leak but I have never lost/burned oil between changes at all with my current motor.

sounds like the front china wall is leaking or a valve cover is leaking and the seals need to be changed.
