The one I have doesnt sit anywhere near that low on the springs. I ordered the jegs tool that people said work.

I think I'm screwed. I have the same Jegs tool and was planning on doing my springs this weekend.

Just finished finally. Once I figured things out and bad the right tool it was easy. Just had a bitch of a time getting it done.

My 02 c5 zo6 with 48000 mi had the yellow valve springs. They can break at any time without warning, when it happens you get to buy a new motor.

I broke 2 sockets as well; using an impact driver will help.

I own a low mileage 2002 Z06 that is driven gently with RPM's usually never over 3500-4000 . Build date in Feb. Not sure what to do about the potential valve spring issue. I would have to have the work done for me and wondering what a fair price parts and labor would be. Car has never been at the track or raced. Any suggestions or comments would be appreciated.

I own the same year car with a build date of early April. For peace of mind, I had my mechanic, Rick at http://www.rktperformance.com change the valve springs. At the same time, we changed plugs, wires, valve seals, and gaskets. Labor was $400. Parts were in addition. Bought all my parts at what is now https://www.cultragfactoryparts.com, a Forum vendor. Work was done three years ago.

Unless, you're a gambler, and the odds are not in your favor, I would change the valve springs. Pay the cost now or pay the cost later. Now, would be around $700 or so, or buy a new engine later and later very well could be tomorrow.

Also, I hear that you no longer can get a factory LS6 new or rebuilt engine. If you need an engine replacement, a LS3 would be the package to go with but, if you live in a smog state like California, you will not pass smog.

If you elect to make the right choice in replacing the valve springs, like a few previous posters have said this would be the time to replace the seals, etc. Also, I would replace the cooling system hoses and coolant if you haven't already because they are 15-16 years old now.

On my 2002 Z06 I added Lil John's Springs with Ti retainers, revs awesome now. Has only 11k miles.

I I agree with others if you feel lucky. Doesn't matter how low the milage or how gently driven. They can go at any time. My job cost 900, expect between 700-900. Have a good corvette shop do it unless you are a good mechanic.
