1991 Dodge D250 ProblemsEngine 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.
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.
A condition may develop where the fuel gauge reads empty with too much fuel still in the fuel tank. Our technicians tell us that installing a new wire harness that provides a common ground for the fuel gauge and sending will correct this issue.
