I have a 2017 Equinox, when I went to add oil to it there was a light tan ring aound the bottom of the oil cap. The same color oil also poured out of the hose that connects to the side of the plastic engine cover.
The spark plugs look good for 130,000 miles, dry, not burning oil.
Is this a faulty PCV valve causing this?
If so, what engineer at GM thought it was good to have to remove the intake to replace the PCV valve?
