What exterior color and interior color does your z06 have? How long you owned it and have you had any problems with it.have you changed the valve springs or was that just a 2002/2003 problem? I have owned mine since 2016. And have been debating weather to change the valve
Springs.its not expensive to do.

I've owned it since 2015,it has 24000 miles and it's blk/blk/mod red.Knock on wood no problems yet.I plan on installing a lmc5 module to fix the steering lock problem.I picked up the kit on eBay.I also plan on installing new valve springs this spring,even though they claim that Gm solved the issue by the middle of the 2003 model year.I also installed a Elite Engineering catch can,and would highly recommend it.It keeps your intake clean of oil.I also installed a Vararam VR-B2 cold air intake.

Yes i installed that lmc5 on my car this past summer works great. If you can get the skip shift eliminator from the same company it is top notch as well

Simple to know if your C5 has the bad or good valve springs is pull 1 valve cover

If the springs are YELLOW then they are the bad batch made
If they are BLUE then they are the replaced designed ones and are fine


It would be hard to think if they are the yellow ones that used bad metal would still be unbroken since mid 2003 and 2002 model years.

Thanks for the info,I'll pull a cover as soon as the weather breaks here in the Northeast?

To save time you might want to pop off the oil filler neck from right valve cover and with a small mirror
or bore-scope and look at the color of springs for #2 cylinder

Saves having to take off coil packs, mount, sparkplug wires and valve cover, might need a new gasket doing this
