Cummins Inc. (Cummins) is recalling certain Cummins Westport ISL G engines manufactured September 13, 2007, to September 23, 2015. The affected engines were sold for use exclusively in Mack Trucks and Navistar vehicles, both as original equipment and as replacement equipment. These engines have a turbocharger oil supply line that may contact or interfere with the turbocharger inlet elbow, clean air intake clamp, or the air fuel control tube, and result in an oil leak.
If the turbocharger oil supply line oil leaks in the proximity of the engine exhaust manifold there would be an increased risk of a fire.
Cummins will notify owners on, and dealers will inspect for oil supply line interference or damage, eliminating the interference and replacing the oil supply line, as necessary, free of charge. The recall began on November 23, 2015. Owners may contact Cummins at 1-800-343-7357. Cummins' number for this recall is C1673.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
