I second that. Just take everything out. Replace all the gaskets while you're in there. If you need new ones, get them from Wayne at Phase2 (he can probably overnight them to you). Get a new mani gasket (it WILL rip) and get a new gasket that goes between the mani and the turbo.
Then get all new stainless fasteners and lock washers so that sh*t doesn't come loose again.
