I too have the piston slap problem with my 2002 Silverado hd 6. 0l engine. I took it to the dealer at about 2400 miles and was handed a technical bulletin that was dated from 1999 (problem has been known since then) telling me that gm is working on a "fix". They did want to look at the truck to make sure nothing else was wrong. There is no "fix", just an extended warranty on the engine alone even though I already paid for the extended warranty for the entire vehicle. You cannot get the warranty agreement mailed to you to look it over, they will only send it if you agree to accept it over the phone. Bought the truck in good faith and was sold a lemon. Maybe if their profits were affected by a recall they might think twice about stealing and lying to consumers.
There have been repair attempts none have been fully sucessful. No safety defect listed.
On 12-2002 oil light came on check dip stick no oil then 8-2003same thing happen this time service tech came out put 3qt in.
Engine makes loud "ticking" noise when warm at idle. Gm states normal condition. Not all duramax deisels make this noise. It cannot be normal. Gm has no interest in pursuing. Although this may not be a safety issue, unless the engine explodes as a result, it still is very disheartening that gm will release the product with bugs and the customer is forced to accept.
Engine has a cold knock when starting up in mornings, also GMC has acknowledged the problem. It's a characteristic design in vehicle.
