THE MECHANIC SAID IT WAS AN ELECTRICAL ISSUE WITH THE OIL PRESSURE SYSTEM. THE NEXT MORNING A MECHANICAL GAUGE WAS PUT ON THE TRUCK AND SHOWED NO OIL PRESSURE. A GEAR HAD SHEARED OFF THE OIL PUMP. IT WAS REPLACED. WE PICK UP THE TRUCK ON 5-2-08, WOULD NOT START AND HAD TO BE JUMP STARTED. DROVE APPROXIMATELY 30 MILES THE ENGINE THREW A ROD THROUGH THE SIDE. IT IS STILL IN THE SHOP. CUMMINS OPTED TO REBUILD THE ENGINE RATHER THAN REPLACE IT. THE TRUCK IS EQUIPPED WITH A SLEEPER WHICH WE ARE AFRAID TO USE BECAUSE OF THE WIRING. WE HAVE BEEN TOLD THAT OUR TRUCK IS NOT THE ONLY ONE WITH OIL PUMP FAILURES. THEREFORE WE WOULD LIKE TO REQUEST A FULL INVESTIGATION INTO THIS MATTER. *TR
