I bought the truck in June of 2000 and the noise started about 17 thousand miles. I complained bitterly to GM, and they finally give me a 100 thousand mile or 5 year warranty. It kept getting more noisy and I took it back to no avail. They said it was piston slap and would not hurt the engine. Now I have about 95 thousand miles on the truck and it is so noisy it is embarrassing to start it with someone around. It may never cause the engine to fail but the problem is if I sold this truck to you today you would bring it back tomorrow because the starting noise is terrible. I'm not sure what a dealer would say if I traded it in, I suspect my trade in would be discounted for the noise it makes when it starts. I've tried several thing to help with the noise to no avail. There is no fix according to several mechanics I've talked to, just drive it and hope for the best. GM has had this problem for a long time and has just swept in under the rug.
