waste gate dump valve always open?
i recently put a turbo system back together and had an issue that id like some help with. it has a tial wastegate that has a plumbed dump tube to the bottom of the block. when i started to drive the car i noticed that the exhaust note was loud and i found that was because there was exhaust coming out of my dump tube. thats not always supposed to be open, correct? what could i have possibly hooked up wrong to have this happen?

please, bare with my inexperience here. i took the wastegate off of the manifold and removed the dump valve tube when it was in working order. i simply bolted the wastegate back on and reinstalled the dump valve tube and now i have this. when a wastegate is uninstalled are you required to install a valve seat when you reinstall it?

The valve seat looks like this:
It goes in the bottom of the wastegate and sits on the mounting surface of the manifold. It can sometimes fall out when removing a wastegate from the manifold. Doublecheck that yours is still there.

Re: (inspyral)
ah, so in other words the valve seat is what seals the wastegate to the mounting flange...got it
