MB Mechanic said the same thing to me. But I don't know the impact this will have if not treated.
I have an wagon! I thought the head gasket was going but realized that couldn't be the case. It has to be the PCV housing. It's not much. I lose about a quart every 15,000 miles. But it's annoying. Sometimes it the oil drips on the hot engine and smells like it's burning oil.
noticed oil leak all over valve cover and coils. in process of taking apart looking for leak or leaks
