Question about 2002 Chevrolet Silverado 1500
THIS STARTED THIS WEEK...WHEN I TURN ON MY 2002 SILVERADO....THERE A LOUD CLICKING SOUND...WHEN I DRIVE OFF AND THE TRUCK WARMS UP THE SOUND GOES AWAY.....COULD THIS BE BELT PROBLEM?
It could be an exhaust leak
It could also be the infamous "Piston Slap" common in 1999-2002's.
GM "standardized" pistons or something like that and they did not fit the cylinders tight enough. The piston "slap" the cylinder walls and make a tapping sound for the first few minutes until the pistons expand to fit. GM would not fix it and says it does not hurt the longevity of the motor ( yeah ri--ght! ) Do a google search for piston slap.
My 02 silverado has done this since almost new... now 145,000.

Nope. This is an Exhaust Leak. You need to replace the Exhaust Manifold Gaskets.
