If engine oil comes into contact with a hot surface, there could be an increased risk of a fire.
Correction:
Cummins will notify owners on behalf of mack, and cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ecm) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. these repairs will be performed free of charge. the recall began on june 12, 2015. owners may contact mack customer service at 1-800-528-6586 or cummins inc. at 1-800-343-7357. mack's number for this recall is sc0391.
