Just found GMI and joined. Looks like a great resource for GM/Chevy owners and I'm hoping to share what I've learned (mostly frustrations!) as a newbie Chevy Truck owner, and hear from experts who know the ropes.
I have recently learned about the infamous condition known as Piston Slap (www.pistonslap.com), and am trying to get the root of the matter in terms of:
1. Is it really a "customer annoyance" issue, as GM claims in there tech bullitens, or is is a time bomb in hiding? I come from a manufacturing background, and in my humble experience metal slapping metal is NOT good in any case, regardless of whether or not you find it "annoying", as GM claims.
2. What is the best approach to determine the severity of this condition?
3. What is the relative cost of a rebuild on a 5.7L V8 vs. a crate replacement engine? I'm not experienced in "big" overhauls such as this so I'm trying to weigh my options with keeping the truck or getting rid of it.
I own a 2001 Silverado with 98K miles. 5.7L, Z71, LT, extended cab. The automatic transmission just died and I put in a Jasper rebuild two weeks ago. That came out of nowhere as I just returned from a long road trip and experienced no issues, literally, until I pulled into my driveway. So, there's the only silver lining I could find
Other issues I'm frustrated with:
I bought it certified pre-owned from the dealer. It was a lease return, one owner, 53K miles. Right after the warranty expired (3 months) all this crap began (see list). Keep in mind, this truck had a 270 point inspection to get CPO status, according to the dealer.
- Dash lights started dropping like flies (55K miles)
- Power mirrors quit working altogether (60K miles)
- The gas gauge went haywire (57K miles - $700 sending unit repair – known GM issue, no recall or dealer fix)
- Piston slap (www.pistonslap.com) (80K miles)
- AC and/or heater core is failing (85K miles)
- Transmission died (97K miles)
Any inputs/advice/clarity is GREATLY appreciated.
