The owner brought this truck to the shop with a claim of lack of power.  Our diagnostic process led us eventually to a compression test.  The test results were disturbing, with compression numbers around sixty-five psi.  A wet compression test brought results up significantly, leading us to believe that a piston ring sealant problem was the culprit.  The removal and inspection of the motor made apparent several glaring mistakes in the motor's construction.  A rebuild was in order.

After the machining process, the images below show some of the process of constructing the motor.  As you can see, we maintain a clean, organized environment to assure the project we are working on gets done right the first time.  We tried, per customer request, to only replace the parts that had failed, or were absolutely necessary replacements.  On that list are: all new bearings (main, camshaft, and rod), piston rings, and several faulty valves.  The block was bored .010° and the crank was turned down .010°.

Significant gains were seen both in horsepower and torque after the rebuild.  The owner explained the difference best when he said, "The truck is fun to drive again."
