When you say you hope it's covered under warranty, I assume you mean Carmaxx's warranty? Who knows with that? But I would sure like the know the outcome if their warranty will cover a new motor.

When you bought the car, it had over 25K miles? You don't know how the car was treated for that first 25K miles. It could have been tracked and beat to chit. The Z is a potent car, but if it was abused for that first 25K miles, then you may have been on borrowed time.

Good luck. Let us know if your warranty covers the blown motor. If not, I won't ever purchase a Carrmaxx vehincle ever.

well i didnt have the money for a new 1 but i payed 45k for a car i drove 6k miles..its at the dealer now..if its not covered i will sue them..i paid 3k for the extended warranty....valve spring shouldnt brake on a car with 31k

Bummer.

I'm sure you know this but the GM 5 yr/100K power train warranty didn't start until the 07. Good luck with the warranty claim w/CARMAX.

This is interesting. I will be curious to know the outcome. I have a 2006 with 13,000 miles. I bought it with 10,000 miles 4 months ago, and my slave cylinder failed. I bought a $1,500 extended warranty from "Fidelity", and they wouldn't cover the repair. Anything that has to do with the clutch, mechanical failure or not, they won't cover, BUT if my motor blows, they'll cover that all day long.

I do agree w you, the valve spring SHOULD NOT break on a low mileage car, but again, the previous owner could've been romping on it since new. Goodluck and keep up posted!

yeah i know...thanks guys ill let you know what happends....i asked the dealer what would cause this and they said he didnt know....i could see if we where at 7k rpm's but on the interstate in 6th gear....i have had my share of cars over the years and not 1 valve spring have i ever broke....had my 05 ls2 got it new put 48k on it no issuses traded it for the z....bad idea for me i quess

All most seems as though an aftermarket mild cam and springs kit may prevent some of these valvetrain issues.

I thought the 5/100K Powetrain warranty started for the 2008 model year.

z0sicktanner

i looked up the guy that had the car before me...hes 68 years old i dout that he was beating on it

I have a 2006 ZO6 with 44105 miles still runs great but I still have GMPP until 10/2012 car is stock.

Exactly. You were basically cruising, taking it easy, and bam. Same with me. I was cruising in 6th, and all the sudden my clutch fell to the floor and the car threw itself in neutral, and that was that...

saleentim

No way i'd buy a Z with 20k+ miles.. I dont care who drove it


Good luck on getting it fixed though

JWell

was the broken spring on the intake valve or exhaust valve?

u1arunit

'07 cars actually..

z0sicktanner

number 7 let loose....not sure if number 7 has anything to do with it or not....the inspector from carmaxx came and looked at the car today..the dealer said they are pushing for a new crate motor but its up to carmaxx at this point....been waiting by the phone all day.....this really sucks

RichieRichZ06

Who are you going to sue, GM? You should sue Carmax for selling you a warranty for $3k when it only costs them $1k.

z0sicktanner

im not sure if it was the intake or exhaust they just said number 7 had a broke vaule spring

LFZ

I'd like to see the look on the guy's face at Carmax when he finds out how much a new crate LS7 costs. Hopefully they will take care of you.

z0sicktanner

no not gm carmaxx......i paid $2980 for extended warranty...
