Broken Valve Spring
Finally caught up with my 2003 Z06.
Not my video but this is exactly what my car was doing -
Proof was in the pudding -
Got the blue ones going in right now

You should check-in here: c5-z06-discussion/list-of-c5z06s-with-failed-valvesprings-not-always-high-mileage-pics.html
It would be nice if we're able to build up a database of these cases.

Consider yourself very lucky. My spring broke and let the valve fall into the cylinder,,,,cracked the sleeve, bent the rod and cracked the piston head.
Now I have a 10 year old z06 with a 4 year old ls6 and a depleted bank account.....thanks GM.

Hey Mike,
My all stock motor 02 Z with 23k miles goes in Weds for new springs (PSI Beehives) as preventive maintenance. The random issues reported on the 02's & 03's prompted me to have this done as insurance against a possible failure while at speed on track and all that would go with a motor issue.
I will check in with the other thread and report any findings on the condition of the original springs.
Will I see you this Saturday at the Valley GTG ?

Except for the name this could have been my experience. I just finished my springs, and my story was the same; at idle it broke and I drove it 25 miles to home. The previous owner lost the valve, head and piston for a $3000 repair bill. I (and you) were lucky.
I have the good spring tool I'll sell cheap if anyone needs it.

How much will this cost including labor?

When I did the springs I used Comp 981s. There were three different colors when I opened it up. It boggled my mind that they didn't do all the springs with the spendy rebuild. The spring I broke was the stock yellow one, I assume original equipment, but not sure so can't answer your question. I have never heard of anyone having to replace a replacement though.

Its hard to believe they only replaced the broken springs. Its good to have the 918's in there now.
Jim, I am interested in buying the tool from you today if the price is right. I have PayPal ready. Just let me know what tool you have and how much you want for it. I am holding off my order from Summit until I hear from you as I would like to save some $ if I could by purchasing used.
Thanks in advance!
Chris
