I don't believe the intake has ever been disassembled, but I can't say for sure as I bought the car used. I don't see any evidence in the service records though. Originally posted by Blake Heisler: I'd say replace your two TB gaskets first, check and make sure all your hose clamps are tight and your BOV flange and BOV aren't leaking The boost leak is very audible and I have no doubt that it's coming from the throttle body / EGR valve area. I may have other leaks, but this one is by far the worst and drowns out any other audible leaks.

Thanks guys. I appreciate your help.

Maybe this is why you didn't notice a difference when you upgraded your BOV and UIP.... Like the other guys said I would check the TB shaft seals and the TB gasket before I went anywhere else.... you kinda have to do this in the order of the biggest leak first.... and I would say that if it starts leaking @ 5psi and bleeds down fast.... then that is a big leak.

I was looking into this last year, the dealer doesn't sell just the seals, you have to buy the whole throttle body. I was going to look for some seals this spring but then Andrew came out with the group buy. They are a special o-ring with a metal center, you can't just throw in any ordinary c-ring.
As the car sits I can't get the system to hold any pressure. Pumping in 30+ psi, the gauge would only go to 5psi and as soon as you take away the air it doesn't hold anything. When you have such a boost leek your turbo has to work extra hard to build and maintain boost....but I was still able to manage a 13.2@105 with these leeks.
