We purchased a 2001 Grand Prix 3.1 70000 miles. Dealership replaced lower intake gaskets due to slight seeping upon purchase. Did not appear to be a concern.. Shortly there after there is a ticking sound (like a sewing machine) coming from the engine. Loudest during idle and when engines cold. Much quieter and occasional when driving. Added sea foam to the oil, and did an oil change...no change. No fluid leaks, runs great. Local shop listened to it, and instantly said the engine was shot. Having a heard time grasping this. We decided to check the spark plugs. Ticking stopped when we unpulled the spark plug on cylinder 4, started again when replugged. Could it be anything other then a shot engine...like it said it runs perfect. Any ideas??
