DISCUSSION
Customer may complain of high oil consumption, grey oil smoke coming out of the exhaust or breather tube, or mechanical knocking. Neoprene compounds used internally in the manufacture of oil filters not recommended by DaimlerChrysler may separate from the filter, lodge in the piston cooling nozzle, and can fail the engine.

NOTE: THIS IS NOT AN ENGINE DEFECT. (See the table below for a list of oil filters recommended by DaimlerChrysler for use with the 5.9L Cummins diesel engine.)
