Five problems related to engine exhaust system have been reported for the 1998 Plymouth Voyager. The most recently reported issues are listed below.
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.
My19 98 Plymouth Voyager with the 2. 4ltr engine developed an oil leak at approx. 49,000 miles. After tedious searching, I found the leak was confined to the head gasket. Which has turned out to be a very expensive fix. I asked Chrysler if they had encountered this problem, and was told no. So then I decided to check the internet, and lordy lordy the place was overflowing with a multitude of the same problem. I feel that this is a factory design problem, which gives to a serious possibility of loss of property or life due to the oil leaking could catch fire as it drips and mists it's way under the vehicle. The exhaust and converter are both in the path of the oil. Chrysler should reimburse all moneys paid in trying to correct this problem.
Daimler/Chrysler 2. 4 liter dohc cylinder head gasket leaking oil on hot exhaust system.
While driving car stalled which resulted in an accident. Vehicle was checked by dealer, who advised consumer that exhaust valve had broken off, and went through the piston, damaging head gasket.
