I don't think it's the LS2. I think it's the mechanic. :iagree:

Yes, they do. It's actually a heck of a deal if you can get a dealer to certify the used car.

As I said, Pay the difference between a new LS2 and LS3 and have 08 and newer power. You get the price savings of a new LS2 plus free install. Thats a win win.

There are apparently significant differences between the '05 and later computers, has anyone done this switch?

A LS3 does use a different ECU than a LS2. It isn't a plug for plug swap either since the connectors are different. However the two modules perform the same functions so it should be possible to use the LS2 ECU with a LS3 engine. In fact that's likely the only practical way to do it in an automatic car. In a manual car you could swap ECUs if you liked, but you'd still have to rewire the harness. But in an auto car, the ECU has to cooperate with the TCU, and both are different in an '05 from the later cars. So you'd need to stay with the '05 modules unless you swap the tranny too.

The motor could have been contaminated with metal shavings or it was not cleaned properly before assembly. I've seen bearings go in 70 miles because of this.

. I certainly do not want to have this balancer problem while crusing down the "Corvette Lane " on the interstate.

Merry Christmas and Happy New year

By the way for others out there I found information in the C6 tech and performance forum searching "balancer pulley problem"

According to Van Chevrolet, my 05 has the balance of the 100K warrenty. Otherwise I would not have bought this particular C6.

I think this is exactly what happened. Of course no one will tell me. As long as I get a new crate engine, I will be happy. Only down side is I have to be w/ out my vette for 2-3 weeks to allow the power plant to be shipped from where ever they are.

That's exactly what happens. The balancer is on the outside of the engine. The debris problem happens from clueless grease monkey using air powered rotory tools cleaning gasket material, throwing aluminum shavings everywhere. Then throw the motor back together without proper cleaning. Or don't check the bearing clearances. Either way those bearings were set up for a short life.

Dealer should be eating the cost of this one, but I'm sure they'll blame it on a defective piston theory.

Make sure they use a different technician. The first one is a POS that would be better suited working on used lawnmowers.

Here is a link that has a lot of explanation of scotch brite/sanding disk debris damage.

Whenever you have engine work done, and shortly there after the crank and bearings get wiped out and look all grooved up or spun bearings. This is likely the cause:

Good to know, I had no idea that was part of it. Good deal for you

Good luck with your new motor install.
