Wish I could tell you more here; unfortunately the only thing I can say is that I think that'* the same part that cracked on mine some years ago, and the local service place (I didn't bother going to the dealer for this) replaced it with a metal version. It was a plastic port or nipple where a heater hose or bypass hose (I forget which) connects to the intake manifold. They put in a metal replacement and it'* been fine ever since.
I don't think they needed to pull off a whole lot to reach it, either; I think it just screwed in. Once you get your replacement part, you should be able to tell from looking at it how the old one will need to come out.
