My ****** in-law started her Monte Carlo the other day and hear a loud tapping noise coming from the engine. We suspected it was a valve issue, so my father-in-law drove it 3 miles to a repair shop where the sound continued. The repair shop was unable to diagnose without opening the valve cover. Since the, the noise has disappeared. Is this something that has to be fixed immediately? It's the L36 version of the Buick 3800 V6. Oil level is fine and has been changed recently.
have the same problem?
