We own a 1995 Pontiac Transport. Today we found a cap on the driveway where we park the vehicle. It's about the size of a bottle cap, and has the initials ZU on it. It has an oily residue on the inside of the cap. The cap does not have threads. It was found on the ground near the front/middle of the engine compartmen. Does anyone know where this could be from?
