1994 Dodge Ram Wagon B250 Problem Reports
Report A Problem
On the 3.9L V6 and 5.2L V8 it is often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
Some vehicles may exhibit one or more of the following: Spark knock complaints when the vehicle is under load, various single cylinder misfire, and surge in 4th gear (around 45 mph). Our technicians tell us that rerouting the coil and spark plug wires
to minimize induction effects will commonly correct this condition. If wires must cross during the reroute procedure, they must cross at a 90 degree angle.
A squeaking/clicking noise from the rear of the vehicle may be coming from the rear springs. Our technicians tell us that a kit is available including spring tip liners and clinch clips.
Delayed transmission engagement of 2 to 8 seconds may be noted after the vehicle has been parked for an extended period. Our technicians tell the repair involves installing a drainback relief valve in the transmission oil cooler pressure line.
A delayed upshift condition may be experienced for about 1/4 mile in cold weather (32 degrees F and below) and is most noticeable after the vehicle has been parked for 8 or more hours. Our technicians tell us the repair involves replacing teflon governor drive seal rings with cast iron seal rings.
Leak detection pump failure can be caused by the internal diaphragm switch sticking, or in some cases, contamination from debris or carbon particles from vapor canister. If black carbon particles are present in the LDP, replace vapor canister in addition to LDP. The purge solenoid should also be checked for debris or carbon contamination and replaced as necessary. All evap system hoses are subject to cracking and splitting causing leaks, Inspect hoses carefully. In cases of contamination from carbon particles or debris, all hoses and tubes must be blown out with compressed air to remove contaminates.
Oil seepage can occur at the speed sensor or speed sensor gear adapter (speedometer adapter). A redesigned speed sensor is available and the adapter may need to be replaced.
