    What’s this part called, should be a raised tube but it’s disintegrating - Album on Imgur

    Parts stores have no idea what I’m talking about and the dealerships computer wouldn’t let him select it individually, said it was a permanent part of the lower intake manifold, but mine is plastic and deteriorating. Many videos on how to replace LIM gaskets say to replace them but don’t say what it is called. Thanks in advance

    Cars without a supcharger have a thing there for the EGR and it will cause the plastic intake manifold to melt and leak coolant into the engine. The new design is what I call the stove pipe that is smaller in diameter and will not touch the UIM and stops the melting.

    Cars with a supercharger do not have anything that goes in that hole. I've never installed anything there on a L67 or L32 intake manifold. Just put a new gasket on there and away I went.
