I have a 2000 Silverado 1500 with a 5.3 that has had the piston slap/clatter at startup since it had about 70K on it. I've run the factory recommended 5W-30 conventional oil and AC Delco filter on it the entire time I've owned it. It now has about 165K and still knocks/clatters at startup the same way it did at 70K... I do agree that it does hurt GM's reputation from a consumer perception view (I sure as h**l wouldn't buy a new vehicle that made that noise!) However, with the miles and hours that are on my particular pickup at this point, I guess I can't really see that the noise affects the durability and longevity of the engine from a technical standpoint. Does anyone have a confirmed "kill" due to the infamous and chronic cold startup knock/clatter?
