What causes white sludge under the oil cap?
If the vehicle has recently overheated or started running funny, the white sludge on your cap could be a preview of the oil traveling through the engine and sitting in the oil pan. A blown head gasket will allow coolant to leak into the oil passages and/or the combustion chamber.
Why does my trailblazer not have enough oil?
Running without enough oil to keep pressure in the crank case will certainly look up the engine. It’s not a matter of if it will lock up the engine, it’s only a matter of when. The oil pump is responsible for taking the oil from the oil pan and pumping it through your Trailblazer’s engine.
What happens if you have sludge in your engine oil?
Clearly, if engine oil does not circulate correctly due to sludge, the VVT system fails. This sets engine fault codes and can lead to engine power and emission control problems. If foam or a milky substance is present in the oil, corrosion and damage to internal engine components is inevitable.
What to do about White Stuff under the oil cap?
When this happens, you are increasing the risk of forming a frothy sludge under the oil cap. If the engine bay requires cleaning, it is best to use low-pressure water spray. It is also important to avoid spraying engine seals such as those found in the valve cover.

What happens when you put sludge on your engine?
As it settles, sludge can clog narrow oil passages or the screen on the oil pickup tube, restricting oil flow to vital parts, especially the upper valve train. Deposits can cause the rings to stick, reducing engine compression and horsepower.
What causes moisture build up under my truck’s oil cap?
There is a variety of reasons for this buildup of sludge ranging from simple moisture build up to severe internal gasket or component failure. Moisture naturally builds up inside an engine, especially in cooler areas and damper climates.
