You can find one in the junk yardQuestion: When replacing the spark plugs in my wife's 2010 Traverse, I consequently lost the PVC 90 degree fitting that goes directly on the top of the intake manifold (you can see it prominently when you remove the plastic engine cover). The fitting goes to a rubber hose that goes to the rear of the engine, near the firewall. What is this fitting called, and does anyone have a part number so that I can order it?
