Voyager 6-cyl

1998 Plymouth Voyager 3.3L engine has a defect in the design of the metal bellows on the engine crossover pipe. The bellows is meant to absorb any thermal movements created when the exhaust piping heats up more than the engine. Either assembly issues, fatigue design of the bellows or a susceptible material has caused a significant number of failures on this part. So many so that I have had difficulty procuring the part from the manufacturer. Upon failure the bellows developes a crack that propagates all the way around it. Exhaust gases then leak out and at slow speeds appear to be pulled into the passenger compartment through the car's vent system. I've tried to patch the repair but I've been unsuccessful. Our local dealer won't perform exhaust work. I believe that this should be a recall. The failure number is based upon a number of backorders that I was told the manufacturer had on this part.

Gasoline odor/exhaust fumes were coming into the vehicle through the heating vent on the passenger's side while driving at various speeds. This was due to a flex cross over tube located between the exhaust manifold. Dealer was aware of this issue, but the replacement part was unavailable.
