Silverado sounds like a diesel

Do a yahoo or google search for piston slap. There lies your answer.

Doc, Thanks for that. I followed your suggestion and read about the piston slap. After reading about it I still don't know if this is OK to have it or not acceptable at all. And if so what I need to do about it. What is your opinion?

Thanks.

IS.

Well, regardless if it's ok or not, there is no permanent fix for it, so you're stuck with it! In my personal opinion, if GM says it's ok and won't shorten engine life or anything else, I wouldn't worry about it.

All these folks who are saying that it's a GM cover-up/screw-up aren't using their heads. IF it was a cover-up, and IF these engines will die prematurely, how many "repeat" customers will GM lose worldwide as a result? If this was truly an issue of longevity/performance, GM would likely rather recall a kajillion engines and eat the cost than deal with persons who will NEVER buy another GM vehicle because of their slapper.

It affects Ford and Toyota motors as well, so it's not some massive GM screw-up like most websites would have you believe. Just a result of the newer engine designs most manufacturers are using nowadays.

I;m going to go out on a limb - and I don't have near the knowledge some of the folks around here have - but I'd be willing to be the price of an oil filter that it's your oil filter. Change the oil again and use anything but Valvoline and get a decent filter. Purolators have always worked well for me.

There's a link to an oil filter study that I'm sure someone has bookmarked that is pretty interesting.

The limb you went out on just broke and you fell flat on your ass bud.

My slap is not as bad as the website, but GM did "change the oil-ring on the pickup tube? and it seemed to help for about 3 weeks.

Piston slap.

Biggest coverup job GM has ever shoved down the publics throat.

Live with it cuase Chevy aint gonna fix it.

I traded in my new Silverado for a Toyota after 3000 miles because it sounded like a diesel and ran like a $800 dollar truck, but mine did it all the time. People would stare at me as I drove it, I took it to the dealer 6 times, they told me that was normal. Customer no service said they could not help until the dealer find's a problem, only problem the dealer couldn't find a problem the scan is normal (no faults).

later My boss know's the service manager at a local dealer who later got the truck and they found a spun piston bearing (go figure, it suppost to run like that).

I will never buy a new Chevy the rest of my life. an older chevy that I can work on sure, but never a new one

Well the crankshafts and rod bearing concepts haven't changed since the small block Chevy was designed. Being a new vehicle doesn't make a spun bearing any harder to detect. They just didn't want to do it.
