2002 Ford F-150 Mileage: 83,408. The motor locked up on him with no warning as he was driving down the road. We contacted our local dealer and had the vehicle towed in. They looked in the motor and told us that there was no oil on the timing chain or on the valves but there was oil in the oil pan and it was black. The only thing they seen was a little "sludge" on top of the valves. Other than that they have not gave us any other indication as to what has happened. Do you have any ideas as to what may have caused this to happen?

The oil pump or oil pump drive may have failed or an oil pressure relief valve may be stuck open. If the oil is not changed at recommended intervals and/or poor quality oil is used sludge deposits in the engine can develop.
