The clicking sound just started this winter. Had no problem last year. I have a 2006 Grand Prix w/3.8L eng. This loud clicking sound only happens when the car is started in cold weather. After the car warms up, the sound stops. Any advice would be helpful.

Thanks

start w/ simple things, how long has it been since an oil change? also...which grade of oil do you use?? it sounds like a lifter noise.

Thanks for your reply. Something related to the valves was my first suspicion. The car has 50,000 miles. I was running Castrol GTX 10w30. Changed the oil yesterday to Castrol 5w30 and the noise was still there this morning when I started the car.

wierd...

isnt the car still under warrenty? how long does it click for?? mine usually does for litterally 2 seconds in cold conditions, untill the oil reaches the top of the motor of course.

A little lifter clatter in really cold weather (under 10 degrees farenheit) is normal until the oil gets circulating as the previous poster mentioned. If it continues for more than a couple minutes, then you may have a problem.
