When Sherri and I arrived in Youngstown yesterday she said my car smelled hot. This isn't normal so I popped the hood to see a very thin sheen of oil across the top of the engine. Today at the Lordstown Park after our plant tour we were looking at it and one of the guys pulled the dip stick out. Turns out the lower o-ring had hardened and broken. After calling around to various dealerships I found one dip stick at Greenwood Chevrolet in Youngstown. Interesting failure - and the first one reported here.
