When I start my 2002 Trail Blazer (50,000 mi) in the morning I always let it idle for a few minutes. The cars starts fine but after a couple of minutes I hear a loud Clunk from the engine area. It does not affect the idle of the car. This condition does not seem to happen when starting the car warm.
Any idea of what this is?
