When Valve Springs Attack!!

[Nvr_Spds]

First, let me say, it IS an LS1, but everyone likes a little carnage!!

Dropped a valve on the way to work a couple days ago, and it got ugly! Time for more power i guess!

Afterwards, i checked the spring pressures on the remaining springs, and found out they were all bad..

Installed height (1.8") should have been 125lbs.. It was 90
Compressed Height (1.2") should have been 348lbs... It was 260 at most..
Even at coild bind (1.11"), i was still UNDER 300lbs.

On to the aftermath, Enjoy:

This is how the valve was sitting when i found it:

Shrapnel out of the intake manifold. Yes thats the valve stem:

The expensive part:

wow... kinda sucks. She sure let go. Good luck with the new build!

That piston took a beating. I think I'd break out into tears if mine went like that especially after a roughly 6k build.

Oh man.. That looks horrible. Good luck with the new build. I just put 5-6 gs in my Cobra to rebuild the motor.

Do you plan on reusing that piston, or do you think it's too messed up?

Anyone would know that's a joke, however there's usually some bit of humor involved.


LQ build up next?

Hey sweet new paperweights...

 

[truebluedevil02]

[Paulinator]

Im not sure yet. Im more leaning towards maybe a stock bottom end (Its N/A) and maybe a solid head/cam/intake package if i can afford it. I would like a 6.0, but i prefer the weight of an LS block, since im going to keep it semi mild.

Damn, that sucks.

:rockon: Its a little more sneaky now with the Maggy catback!

I completely agree!! If it breaks, build it stronger! The car already has a 4k stall, built trans, and gears, so now its time for an engine i guess.

 

[mysteed]

Wow that sucks.

 

[Nvr_Spds]

It was teh suck! Atleast, now i have an LS piston to hang on the wall next to a busted Lightning piston out of my old truck.

Ha, +1 :beer:

Are those the stock springs? Is the car cammed?

Nope. They are Comp Cams' 918 springs. .600 lift behives. Its got a baby 224/224 .580/.580 114LSA cam in it.

That sucks! I had a very similar event with my old '94 Camaro. It wasn't pretty, either.
