This can happen to any engine. It's usually a result of lack of oil. They may have to replace the crankshaft as well if it's bad enough.

Man... I still treat our Envoy as gently as possible and have done so since the day we bought it. Maybe it's cause I didn't grow up with much money, who knows... It's good that your warranty will cover this repair, but keep in mind that routine misuse could/will result in failures later on down the road (after the warranty expires). It doesn't matter if you run the best oil available if your rawdogging the motor enough to spin rod bearings. I'm sure you're young and excited, but these are nice machines that go for $35,000 new. What about the next person to own the vehicle who may have been waiting and saving years ahead of time? What if they think they are buying a good used GM Certified SUV that will only be a problem child the entire time they are under it. What will they be purchasing with their hard earned/borrowed money? I'm sure you haven't or do not think that far ahead, but it's always on my mind when I read of these "self-caused maintenance issues" which seem to never end.

Disclaimer: I'm expecting a negative reply, just so you're aware. Most people wouldn't admit to doing anything wrong and will defend themselves to no avail. Also, they might feel as though the more mature opinions are somewhat aggressive, but that is not the case. We all care about our fellow Trailvoy owners (brotherhood) and are only helping them by providing proper guidance and counesling. Good luck at the dealership. Oh and one last thing. Keep an eye on GM's stocks, news, capital gains and losses. There might not be a warranty before long.


As usual, my 2Cents,

JD

I'm sorry to hear you have that opinion of our board members. I would like to be the first to say it is my firm belief there are much more intellectually written posts than that of my earlier one. If you feel challenged by the articulation contained within, that's a whole different situation.

Thanks and keep the confidence up.

My2Cents,

JD

I'd expect something a whole lot louder than a valve-tap like sound, if the bearing actually spun, unless you mean more like a collapsed lifter type sound. Just keep in mind that if you're going to beat on it, make sure the motor has a chance to fully warm up first. The odds of damaging something with a cold motor are much greater than once they're fully warmed up.

Johnboy_mr2. So basically your saying..."Don't drive it like you stole it." Respect and think of the other person buying it in the near future. Hmm...k . I guess i better start now and respect it.

I have the same thing happening. I haven't driven it for the last 3 months (it happened while driving home from Wal*Mart the night before I was going to drive from Iowa to San Antonio in it). Spun bearing would NORMALLY cause little to no oil pressure from what I've been told. My dealer is 99% sure it's a wrist pin. They're not covering it due to being tuned (I don't lie, they know all of my mods...and love the crap out of it!). You have to pay to play, brotha!

So, I've bought this stuff:
PSI-LS1511ML "Maxlife" Beehive Valve Springs
Comp Hi-Performance 7* Machined Locks
CV-Products 511 Titanium Retainers
Trend 5/16" Hardened Pushrods (7.425")
ATTITUDE Cam
Katech timing chain
Cam install kit
ARP Harmonic Balancer Bolt (pulley)


NGK TR6 spark plugs (gapped to .030)
Scott's Wires (for headers)

Kooks 1 3/4" headers-coated Jethot 1700 Extreme Sterling
catted 3" Y

Callie's Compstar Forged Rods-6.125" w/ARP
Wiseco Forged pistons- 4.005" bore/3.622" stroke/ 6.125" rod/-3.2cc
Wiseco Piston Rings, 4.005 Bore, 1.5 - 1.5 - 3.0 mm
Melling Performance Oil Pump

Clevite Rod Bearings
Clevite Main Bearings
Durabond Cam bearings
ARP Head Bolts kit-Hex
2 Head gaskets
Rear main seal housing gasket
Timing cover gasket
Exhaust manifold gasket
Oil pan gasket
water pump gasket
Rear main seal
Front crankshaft seal

Then, I'm spraying the crap out of its forged butt!

All I haven't received yet is the forged parts and rings. Should be here by tomorrow, maybe Monday.

Driving it like you stole it applies when one either does indeed steal a vehicle, or can afford to drive, have it repaired, drive, have it repaired, etc... I sure as heck know I can't afford to hotdog my cars around. Furthermore, I don't feel right about being knowledgably rough on a car, and then have the company I bought it from cover the repairs all the time (warranty abuse). This costs GM quite a bit of change and sure as heck doesn't help their shotty business ethics, hahaha. There are 2 sides to nearly every coin.

I know this is common sense to most, but I'm replying to another's post here.



My2Cents,

JD

Now this is the attitude to have! I bet your ride is indeed impressive. How much do you think you have in it total?
