I read another topic and share similar lag and rough start up problems. I'm not here to discuss that but rather the boost leak tester. I've read numerous faqs, but i'm confused about how to put the valve stem on? It may be a stupid question but the picks don't explain how to put it on (jb weld?). I may just be dumb with this one.

Any help?

 

If you're using a rubber valve stem, you'll have to drill a hole just big enough to fit the top through the hole and pull it through as hard as you can until it pops through the PVC top or rubber top. Once that's done, you can apply RTV to make sure that it won't ever leak there.
So, my question to you is, are you using a rubber end cap or a PVC end cap or what?

 

I haven't made it yet but i will go with PVC.
