I recently had one fuel injector go out on my drill rig whitch is using a CAT 3406 on the deck. I changed all 6 at one time. Immediatley after replacing the injectors the engine started using 1 gallon of oil efter every 12-14 hours of use. After approximatley 50 hours of operation the engine threw a rod through the side of the block. Any ideas??
The engine never heated up or lost oil pressure.
