it appears that i have some sludge from the out side of my motor, but when ever i did my oil change on my car the oil was not that bad, is not burning oil.

should i worry or i should just give it a good wash and degrease my engine????

How do you get sludge on the outside of the motor? You mean a leak? Just fix it.

It's probably dirt and oil. Clean the engine and find your leak.
