Well, my van sounds like a loud diesel. But the wife thinks the engine is ready to blow.
The exhaust pipe on the passenger side connecting to the exhaust manifold has separated. It seems that the pipe has a flange plate that makes the flared end compress into the manifold. This flange plate kind of looks like this ...
HOWEVER, mine just rusted and broke halfway off. Of course, the bolts and nuts are solid rust to the exhaust manifold too.
My course of action thus far is to figure out how to remove this rusted flange plate, get the fused heat rusted bolts out of the exhaust manifold without breaking anything, possibly cutting the very short "Y" section, slipping on a "new" flange plate to bolt to the exhaust manifold and to place a "new" exhaust coupling to repair the leg of the cut piece of "Y". :help: Is this possible to do? :help:
If taken to an exhaust place, I could be looking at a new Y-pipe, new flange plates, gaskets, and a new CAT. $$$$$$$
If anyone has changed the oil in any of the 3.9L, 5.2L or 5.9L engines, the Y-pipe to exhaust manifold sits right next to the oil filter by 1-inch.
Years ago, I fixed a friends Ram Van, 1977 by using a mere metal coat hanger slipping it through the flange plate and the bolt hole in the exhaust manifold with vice-grips. It held tight all that summer.
