& that's to change them religiously. Luckily this lesson only costed me a new set of valve springs......live and learn

 

what were they?
when did it happen?
mileage?
other parts to the valvtrain?

more info

 

???? did this happen when installing them?

 

subscribing.... those look like prc duals.

Mileage?
Cam?

we need more info... im interested!!!!!!

 

Cam size, lobe design, lifter preload, brand, and mileage please?

 

This aughta be good. They look like your typical associated dual valve spring setup....

 

well i have a powerloss BAD at 5500rpm ive been chasing... I have the PRC duals, I wounder if mine are getting worn out after only 8000 miles....

I know i deffenetly dont want them to get that bad!

 

Waiting for info as well. I feel I have a powerloss in the upper rpms and I have the PRC duals as well!

 

when a valve spring isn't pushed close enough to coil bind it creates harmonics. drastically shorting the life of the spring. This could be a result of such a thing. A spring that is run .060 to coil bind will far out live a spring that is run a .160 from coil bind,

 

My car has a Lunati Grind 231/237 .595/.598 on a 112lsa and I've ran these valvesprings for 12k miles without issue. I'll be replacing them soon, but only b/c I'm installing ported heads.

I ran my prcs.... cam only with a 227/231 614 617 112+2, then i got an sts kit and ran the same cam and springs, now im running them on my setup in my sig!

about 8000 miles total but i lose 100hp after 5500-6400... and cant find out why and am thinking maybee it the springs are wore out and giving valvefloat maybee.

If the springs are about the mileage mine are im deffinetally gonna change mine!

 

It may be that you springs have fallen off or you may be flexing your push rods, you may want to go to a larger diameter push rod if that isn't an option use a haver wall push rod.

 

I've seen that many times... I wonder if there is a problem with the PRC's ???

 

I will make a detailed post later on. I am replying from my cell phone. They are patriot golds. They did have some good miles on them. It all started a few months ago When the car wouldn't pull passed 6500 it was like the tranny I had was hurt. Upon more test it ruled the trans out. I'll make A more detailed post later on tonight when I get to a computer

 

good deal... sounds like my problem cant hardly pull past 5500. lol

 

Well looks like you ran them on a LSL lobed cam. I will almost guarantee your valve springs are wrecked at 8000 miles. The PRC springs are known to sag over time and with that much mileage on a set of lobes known to wipe out a few valvetrains I imagine it to be the culprit.

 

I've had my PRCs for 25k miles. I need to be looking into replacing them also

 

I DD my PRC platinums for 3 years now, 1 racing season and 3 cams; all over .600 lift and they are still within specs.

The issue poeple tend to miss is *Were the springs installed at correct height for cam used?*

 

woah thats bad, im replacing mine this winter just as precaution after 12k on the cam swap

 

Thats the million dollar question...
