Valve Springs changed..
Had the springs changed out, they were the yellow ones, were those the bad batch?
Also had a left side axel seal fixed along with all fluids changed, and long tubes with X pipe installed..

The original OEM springs were blue. The problematic factory ones would be the same color. The yellow colored springs were the replacements from the factory and would not be a problem. You p[robably have had them changed at least once in the past.

Factory springs were in a variety of colors. Blue, Yellow, Natural, Natural with orange stripe.
I've broke a yellow intake on an 02 with 48k miles, seen at least seven other LS6's with broken valve springs, all yellow.
With that being said the part number changed in mid-2003, and have seen these replacement springs in blue and yellow.
You will be fine as long as they came from a dealer.

It is an early 03, I kept reading about those springs and it scared the heck out of me, so I changed them out for peace of mind.. Hate to kill a good motor with only 15K.. Man you did not drive it much, I got it with I think 5K.. How's the new one?
Breakfast soon I am ready for a road trip!! Will you be at Sebring? If you make it be sure stop in.. I am not going to make it to the 24 hours, infield is sold out..

Blue greenish color came on 01 Z06, and yellow came on 02+ Z06. Yellow on's were the problem, i never came across blue/green went broke. Good thing you replaced and next mod begins......comp Cam trunion kit for your stock Rocker arms, those needle bearings in them are some times let go, i am glad i did.

wrong. the blues are current GM replacements, there are more yellows that break than any other spring out there. Never seen any blues that break.

i have an 8/01 build date 2002 car and it had the natural with orange stripe springs. also had an 01 many years back that had blue springs
the replacements i got from gm back in april of 2013 were also blue
i even tested them on a spring rate meter and they were damn near identical to the natural with orange stripe springs

I just skipped the whole business, I'm running a cam with Tooley .660 duals
Mine is a late 03 anyway, so I got the 04 fuel system and valve springs but without the Nurburgring-tuned shocks...

Actually the new replacement LS2 spring can be Yellow or Blue. Don't have time to give part numbers now. The part number changed Mid 2003 and that part number later became the LS2 part number.

NEVER seen yellow.. part # 12499224 all the new LS6/LS2 springs are blue from GM. I'd be very hesitant to replace a yellow with another yellow.. if that were the case I'd go aftermarket for sure.
