Some 3,000 Units Affected by Turbocharger Oil Supply Line Issue

Cummins is recalling some 3,000 natural gas-fueled, 8.9-liter Cummins Westport ISL G engines. “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,” says the National Highway Traffic Safety Administration.

“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,” says the recall notice.

OEM and Retrofit

The engines in question were manufactured from September 13, 2007, to September 23, 2015, NHTSA says.

“The affected engines were sold for use exclusively in Mack Trucks and Navistar vehicles, both as original equipment and as replacement equipment,” the agency says. The recall applies “exclusively” to Mack trucks.

The total number of engines affected is 2,959. The recall carries NHTSA campaign number 15E085000.
