STS install questions

I'm installing an STS kit on a buddies LS1, the kit he bought was used and didn't come with a Check Valve for the turbo to keep the oil from pooling after you turn the car off. My question is, where can i buy one at?

try calling STS directly, i have heard they have pretty good customer service about that kind of stuff

Thanks, i was going to try that tomorrow morning. :)

guy i talked to at powertour bought a used sts kit for his LS1 camaro, and it did not come with the oil pump, he ended up getting it from them so i would suspect they'd sell the check valve as well
