Question about 2001 Cadillac DeVille
Here is the rule and GM's official stand, if the noise goes away after a few minutes of running that is ok, if it is loud all the time you have a problem, there are many blogs out there about these piston slap noises, I have one in my own car, a 96 Corvette, GM said not to worry it will not cause any damage, just annoying on a car that cost $48,000.
