You need to ask the dealership questions. No offense, but you need to not act like a pansy to them, and tell them to do what's asked. You are their customer. If they want to tell you about some other issues, that's fine. You need to ask about the details. Upper Intake Manifold or Lower Intake Manifold? Where at was it welded?
Basically, you're asking a bunch of people to diagnose your car without giving any details. Find out what's going on with the dealership and report back.
