I changed the valve springs out on my heads a few weeks ago and the car has sat since. The car ran and drove fine after the swap. The car still runs the same but I heard the squeal/squeek sound from the side of the motor so I went to pull the valve covers to make sure the rockers wern't loose. When I pulled the breather and PCV valve they are cover in white crud that looks like a water and oil mixture but there isn't any in the valve cover or on the dip stick. I pulled and cleaned the dip stick multiple time and the oil looked fine other than being low. I can't see any oil in the water. So I don't know. Any thoughts? The motor has about 500 miles on it since the build.

 

that is moisture getting inside there it is fairly normal and wont hurt anything as long as you dont find it inside the motor
