So what are you going to replace that stock valve with? A new OEM valve or an aftermarket one?

chad05gt · June 22nd, 2009, 04:15 PM

is iconel a brand? I know I have stainless valves but no clue what brand they are

unlicensed to drive · June 22nd, 2009, 04:29 PM

I would begin to guess that a inconel valve is an intake valve.

chad05gt · June 22nd, 2009, 04:39 PM

inconel is an alloy usually just used on exhaust valves; it has capacity to remain effective at extremely high temperatures, highly resistant to corrosion. Added heat of n2o and FI they are a must... I just got 'em all inconel; just to be sure.

Not saying the one that Rich is replacing is NOT inconel; if it exhaust valve, it is/ or should be w/ these heads.

UrbanRedneck · June 23rd, 2009, 09:28 PM

well that sucks ass. Those valves aren't even that old either, didn't they come with the heads?

07stanggt · June 23rd, 2009, 09:37 PM

Thanks JPC for catching this and saving the head from coming off.

Here is the culprit, exhuast valve spring on #2. Car is running like a champ again. I think it picked up 15 hp from my new coil packs, maybe 20

Dang rich, how do you think that happened? Btw I'm glad to see your car up and running again so soon and in top shape.

No idea man. about 20k on those springs. quite a few 6500, 6900, some 7500 revs. Lot of revving up and down thru the twisties. the last time i really beat on the car was my bad runs at the strip. Whenever I posted those 14 second times. few missed shifts that day. Other then that, i play around on exit ramps every chance i get, down shifting and hitting the ramps. but usually i shift at about 55 6k on the street at most when i play around. It happened at cruise speed going 65, so maybe it got cracked at some point and just gave out that day.

Ill call livernois tomorrow and see what they say.

unlicensed to drive · June 23rd, 2009, 09:46 PM

It would make sense that the spring being compressed so much from high revving somewhat frequently would make it end up cracking. In a way your car is kind of like a race car, so you have to somewhat expect things like that to happen once in awhile. Thank god it wasn't a valve.

silverstang · June 23rd, 2009, 09:53 PM

this thread scares me............

Oh BTW, I removed my burned valve out of my head today.........WOW. you guys should see this thing in person. It ate the SHIT out of the valve.

Could you possibly post up pics?

7000 RPM is real hard on a valvespring. On cars that live as hard as Rich's, it happens. Luckily it didn't cause any other problems though.

Glad it was fairly minor rich. What brand are those springs?

unlicensed to drive · June 23rd, 2009, 10:20 PM

I'm sure you want to hear the answer from Rich urban, but since Rich got his SPR Cams and Livernois Stage 2 Heads(which come with upgraded valvetrain) installed at the same time, I am almost fully sure that his springs are Livernois brand.

Thanks I appeciate it. it worked out well. Lucky as always for me. Its just the rears i have issues with. LOL.

Whatever comes in livernois stage II heads. Im assuming its the springs they sell on their website for like 150 that are suppose to work with stock retainers.

Im not really complaining. I know the beating it takes. Most guys would be afraid to do twice what i do on the regular to this car.

germansheperd · June 23rd, 2009, 10:26 PM

Not trying to sling mud but damn seems like LOTS of issues with Livernois heads lately.

UrbanRedneck · June 23rd, 2009, 10:26 PM

Livernois makes their own springs? Not sure I believe that, they'd probably be made by comp or some other spring manufacturer.

True but thats why he upgraded, wasnt like he trying do this on the stock springs. They shouldve held,something was wrong-cheap spring,installed height not right,valve lash?
