I've got an '01 so was not concerned about the valve spring problem as the model year lies outside of the heavy failure rate. But I track my car and a fellow track member running an identical Z06 to mine recently experienced spring failure. He was lucky he didn't loose his engine. So I had my mechanic order a kit, it will be installed this week.

Yep, I refreshing the springs as well as seals etc.
When I purchased the vehicle I replaced all lubricants, including the tranny and dif. I recently had a bleeder valve installed for the clutch fluid line. A lot of black fluid came out.
Someone suggested a new cam, I was told it's a big deal to do that, have to pull the engine?

It's a 2002 built in April 02. Right smack in the middle of the bad springs time frame. Mine had 44000 on it I think when I changed them in April of this year. I felt like I was playing Russian Roulette. I was afraid to wind the engine up over 2000 rpms for fear of hearing the motor coming apart at the seams so I changed them for the the peace of mind. Why become a statistic? Better safe than sorry. You'll feel the better for it if you change them even though you're on the extreme tail end of the beast.

Just got a 33,000 mile 03 z (december 02 build date) decided to swap springs to the new blue style. One stocker had already failed. Got lucky it failed near the top and wasn't catastrophic.
