    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.
