GSC cams with cracks

The actual cam is not cracking it’s the coating. I have one set that will be here first of next week we are going to send them out to get ex-rayed so we can confirm this. If this is the case and anyone who has a problem with them we will exchange them for our V2 cam Free of charge including shipping both ways. From what we have gotten as far as people that confirmed the issue it shouldn't be much more that 10 out of the 150 sets of first run cams. As long as the Ex-Ray comes back clean it is going to be up to the discretion of the owner if they want to take them out and replace them with the V2.
Everyone has my word we will take care of this as fast as we can. Sorry for any inconveniences or worries GSC has put you under.
Best Regards,

LOOK! It's Nessie on Lock Ness! 
Sorry, couldn't resist
Seriously though... working with aircraft, any visible stress crack is not good. If it truly is only in the "coating" (still don't want that stuff floating around in my bearings), it probably won't cause a catastrophic failure.
I'm not busting Greg's *****, he is really working on taking care of the customers, and protecting his company's good name

Wow... it's crazy to me that everyone is erupting over this.
Don't sweat it... those cracks aren't going to cause any performance faults, and not gonna blow a motor or anything.
GSC is doing the right thing by exchanging them - but the reality is - they won't have any long term ill-effects on your motor.

GSC went the extra step in offering cams with free shipping both ways just to give its customers a peace of mind. That does not happen often in any business.
I was undecided on what cams to buy but the manner in which GSC conducted their affairs with customer service makes them top-notch and was the deciding factor in making me purchase GSC cams in the future.

I have a set that are out of my car after about 500 miles of use..they do show this color change but I cant tell if the groves are actually deep enough to matter..since they are out of my car I would be willing to send them back for inspection so you will know or can determine the direct cause of this...Feel free to replace them if you feel the need too..Greg at GSC feel free to PM me with info on what to do. thanks
But I must admit these cams KICK ***!!!! monsters...made me over 40hp for sure.

Inspected my cams last week and they look fine no hair line cracks or anything. I have had a bad set of JunIII cams before in my Type R and im running them again. Some time you just run into problems nothings perfect. I stand by my GSC cams 100%.

I see no problems with GSC's V2 cams. TTP.-Engineering.com just installed a set today and quality looked top notch as always. Greg is a great guy and has a do-whatever it takes attitude. Expecting installation reimbursement is out of line however as this "issue" may just be a cosmetic flaw. If someone breaks one in half, then I would like to hear about it. Otherwise, we are just whining about nothing.
Ok guys we have some info for everyone. We X-rayed the V1 cams and found that the cracks or scratches were only on the surface in the recessed part of the cam. we feel that the cause of the cracking or scratches is do to the coating and the heat treating process, the process we used was a little different than HKS's coating, so that the lobes on our cams would be smoother. The reason for the cracks in the recesses is do to excess coating on that point of the cam. The V2 core utilizes the same method that OEM Mitsu uses when making the stock cams. The V2 will never have the same problem as some of the V1 cores.
Here is what we will do. If anyone is having this problem and is truly concerned can take them out of their car at there expense and send them back for replacement, we will replace them with the V2 Cams of the same duration. The cam cores are good and the x-ray turned up nothing but surface scratches or cracks so the cams won’t break. If for some reason you have the V1 cams out of the car and notice them then send them back for a free replacement. Not all of the V1 Cams will have this problem and I suspect only a hand full of the 100 sets that are out there will have the cracking or scratches occur. I wouldn’t suggest taking them to someone to have them removed so that you can just send them in for replacement. However, I understand if you want to and we will take them back and replace them. It’s totally up to the customer.
