1991 Dodge D250 Problems

Engine Knocking Noise From Carbon Buildup

Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.

Air Conditioning Not Cold

The powertrain control module (PCM) may fail resulting in a lack of AC cooling. The lack of cooling could be caused by evaporator freeze-up due to the AC compressor staying on continuously or conversely, not coming on at all. Proper diagnoses of the PCM should be performed before replacing it for this concern.

Engine Oil Leaks

Oil leaks from the valve cover gaskets, timing cover gasket, distributor o-ring, and rear main seal area are common. The leak at the rear main seal area is generally not the seal itself but the bearing cap to the engine block seal. An oil leak could also be internal to the distributor, if oil is found inside the distributor then the distributor should be replaced.

I bought this truck used with many miles on it. The engine had been rebuilt. So far its been a very good reliable truck. Hauled many things and even a medium sized pop up trailer with no problems. Interior is not in the best shape and appears to have been built shoddy to begin with. Exterior all the paint was peeling bad and looks like that might also been a factory issue.
