2002 Z06 Repair or Replace Engine
The fourth (4) broken valve spring resulted in the valve falling into the cylinder, damaging the head, the piston and the cylinder wall.
The vehicle has 85,300 on the odometer and is under warranty.
The dealer wants GM to replace the engine.
I am concerned about matching numbers.
My questions are:
Should I be concerned about matching numbers?
Should I ask for a replacement engine?
If GM will not replace the engine, should ALL of the rotating parts be replaced?
Thank you for any advice you can provide.

Sorry to hear of youe 02 Z engine failure.
It's too late now to worry about matching numbers on your engine.(Best to get a replacement)
Your dealer & GM , have to take total responsibilty for not having ALL the springs, retainers, keepers & seals, changed all at the same time.
This is what happened when the dealer & GM decided to play Russian Roulette with your engine.
If they decide to replace motor with an engine with approximately the same amount of miles, your right back into the same sinking boat, in regards to old springs that need to be replaced.
Good luck.

So they sat there changing out valve springs as they broke on more than one occurence, didn't just do the whole set when the first one broke? They deserve to eat the price of a new engine if that is the case...
Anyway, I'd insist on a new (not remanufactured) LS6 crate engine/long block. That is what mine was replaced with when the engine turned out to be bad not long after purchase, although it was a third party warranty from the Chevy dealer I purchased the car used from.

This isnt a 63 Z06, its a high production C5. Dont worry about matching numbers, its not gonna matter. Demand a brand new crate LS6 and dont leave until they commit to it in writing. PERIOD.

Engine numbers on these cars mean nothing in comparison to matching numbers on older vettes. ANd even then the only people that it matters to are the people that it matters to.
Ive personally alway been more interested in the quality fo the engine in a car. Not the number on it. A few are rare and worht more because of it but none of the vette engines being produced today will ever be rare while we are still alive.
Get a new engine if you can. Much smarter and better choce thatn patching up and older motor because it has soem numbers on it that in reality mean nothing.
Just my thoughts. Good luck to you what ever you decide. Or what ever GM decides for you i should say.

If the cylinder wall is damaged, (along with the other damage) you pretty much have no choice but to replace the longblock. Sure, you could sleeve your present motor, and then replace everything else, but the dealer isn't required to go that far. I wasn't aware that the blocks didn't have vehicle specific number stamping, not that our cars will ever become a collectable. The fact that our LS6s don't have to match works for me, because if I blow 'er up with the SC, I'll have to forge/shortblock anyway. Good luck with your dealer.

what makes you think there are no numbers linking motor to car???? there are casting numbers if not a serial number etched on block I believe. If I wasn't so lazy I would go out and look at a salvage block I have to be 100%. but if it were me I would go crate, less than 6k and if required pay difference and you even get 2yr/24k or something like that on engine or maybe more.
