Broken intake valve spring
Well guys i received the news that i have a broken intake valve spring on my 03 zo6.Heres the scenerio i was driving home from my cousins house and everything is all good all of a sudden my car sounds like its misfiring and tuff to keep running at an idle.No spirited driving at all.My first thought is the maf so i searched the forum gathered as much info as i could and removed the maf and cleaned correctly ,started up same thing running ruff wont idle.I have the extended warranty on my car so in the dealership it goes ,received the call today that i have a broken valve spring.My question is ,isnt this odd for a stock zo6 im running a vararam cai and a catback,i have read that this usually happens to h/c vehicles ? is there any questions i should ask the dealer to look into, or should i have any other concerns Thanks

Unfortunately no, there have been broken valve springs on the LS6. You might wan to consider a full spring change at this point, although they won't cover that under guarantee.

Same exact thing happened to my 02 Z06, albeit at higher mileage. I used it as an excuse to go heads/cam. If you didn't do any damage to the bottom end or head, count yourself lucky. You can get away with putting in a new set of springs, but I would not suggest another set of OEM's... if you do some searching, you'll find that failures are alarmingly common.
