Dirt_Floor_Poor Posted July 20, 2022 Share Posted July 20, 2022 I have located enough good used pieces to put my DT429 exhaust manifold back on. It is a three piece manifold. The center section is new and the front and back are used, but they look very good. What are the chances that they will seal how they are supposed to? I have read in the past that Caterpillar has some kind of a product to seal joints like this. Is it needed, does it work how it’s supposed to? Anybody ever used it?
