GSC Beehive spring failure

GSC Beehive spring failure
If you love your engine, AVOID GSC Power Division parts. I installed a set of GSC S2 cams and valve springs in a customers EVO 8 a few weeks ago. Pretty routine install, I've done tons of them. I had done a full engine build on the car a few months earlier, 10.5:1 compression, Eagle Rods, ect. I get the car back together and start it up to let it idle and warm up before I make some tuning adjustments. The car was running for about 3 minutes and it made a clunk sound and shut off. I tried to spin the crank by hand but it was getting stuck at a certain spot each way. So I pulled the spark plug and looked inside to see the valve sideways in the cylinder. I pulled the valve cover and seen that the spring had broken and collapsed. I took it all apart to see a total mess. I first called MAP who sold me the parts and I was told to call GSC directly. I called them and they told me to send the spring to them to be tested. I sent them all the springs, they tested all of them. From what they tell me all the springs are good besides one being broken. There was no signs of an incorrect installation either and basically is was not either parties fault and they tell me they will replace the one spring. Well I sure the hell am NOT putting these back in after I repair the $1500-$2000 in damage the spring caused me. The break on the spring is very clean, the spring in not bent nor scratched, it just broke, and ruined my customers engine. Well they have refused to help me, so all I can do is help others by spreading the word that they sell cheap junk that can destroy your engine. Please share this and spread the word.

Sodium filled exhaust valve broke...which came first the chicken or the egg? Let me guess, there was over a 100K on the original valves? Picture of the retainer?

I really wouldnt expect a valve no matter what type to win a battle with a piston. The fact is, this happen, and it happen to me. Could be a new bad batch, not sure, Im more concerned with the fact they will not own up to it.
Maybe its a one in a million thing, who knows. It did happen and now I have to pay for it. Luckily there are lots of other companies to buy springs from.

I would say that it if they were willing to replace the spring, take time to check them out, thats better than being told to pound sand. If it was broke or breaking normally it will hang the valve enough that the car Subes out and you can hear its not right, this just went straight to broken?
I understand the frustration but even you admit there many possibilities of what could have caused it so this thread really serves no purpose. If you had phrased this as "Anyone else ever seen this" or "What happened" rather than just putting them on blast you may have gotten a better response, especially considering you arent even a Vendor here.

You didnt really answer the question about the valves lifespan though. We have seen the stock exhaust valves break at 145k more or less. This can go 2 ways on the spring since it can bind if the valve drops.

And Im not just putting them on blast, we have been talking back and forth for a few weeks. I took the spring to a few machine shops, shown the picture to tons of people and they all say the same thing, "Inferior metal", plain and simple.
They are sending me the set back with a new spring, the rest I have to eat.
I am not gonna put these in ANYTHING and these might have cost me $2200 but the first person to post up a name and address will get a free set of GSC valve springs, if they really send them.

They told me it went to a Metalurgist, "They didn't find any issues".
I challenge anyone to break a valve spring without bending or scratching it in anyway. Its pretty clear what happen, you can see all the pics, this spring is flawless besides it being broke in half.

Sorry to hear about the failure. This is rare. We run GSC products in our cars without issues.
