what was the purpse of this post? what is the message that you were trying to get out? i must have missed it completely.

 

well from what ive seen at the dealership is that gm does not see this to be threstening to the life of the engine. it shows up especially in the new style pickups. the majority of vehicles with piston slap usually quiet down after it gets a little heat into the engine. fd720
you said that you work at the dealership, you service manager should be able to bring up some info for you about piston slap. otherwise take it to a different shop and raise hell there. we have a guy that come in with a cavalier and he complained about every bump and noise, which every bump and noise is pretty much a given in a cavy, and gm actually gave him a 100k waranty on it so now were stuck with this punk for that much longer, but i would definately have them put it on record now so there is something that says it was a conscern. you may also be hearing the fuel injectors opperating. i have run into this before. the piston slap is basically a round piston in a egg shaped piston which changes its shape when it expands from the combustion temp. me personally i wouldnt worry about it. my truck has had it since i put my engine in and that motor was straight from the factory. i can understand you conscern but for you working in the dealership they may be able to do something for you but whats gonna happen after 20k miles is it gonna do it again? good luck.

 

Thanks. Yeah, I was looking on SI and found some complaints about noise but it wasnt the noise my car was making. Some of the complaints were pulley noise at the crank pulley some were injectors. Well I guess as long as the 3/36 is there I will be covered. I guess if gas goes back down(very wishful thinking) I may look at getting a redesigned Silverado in 07. I hear thats when the bodystyle will be changed. Who knows, I may get an 07 Trailblazer SS. At 391 hp it will be a bad*** truck.[sm=gears.gif]

 

yeah that thing looks great with the 20 inch wheels and that v8 pushing that thing to 60 mph in 5.7 seconds is pretty incredible.
