1993 GMC Vandura 2500 Problems

Intake Manifold Gaskets May Leak Coolant or Engine Oil

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

Transmission Fluid Leak, Erratic Shifting

On the 4L80-E Transmission (Diesel and 7.4L gas engine), Transmission fluid may leak through the electrical connector on the side of the transmission, damaging the wire harness and causing the transmission to shift erratically. Our technicians tell us there are updated shift solenoids, an internal  transmission harness, and a connector pigtail available to correct this fault.

Distributor Shaft O-Ring Seal May Leak Oil

An oil leak may develop from the distributor o-ring seal requiring replacement of the seal.

Bought it in Reno, Nevada and drove it up to Alaska 2 weeks ago. Awesome vehicle with a smooth ride, smooth transmission, strong but quiet engine, and pretty good gas mileage! Will keep it for a long time! JH
i wish I could drive this thing straight into a tree! can,t stand it. I've put so many new parts into it and still can't get it to run right..... lesson learned "never buy anything from a person named cleatus!"
