oil pan plug gasket

  1. NAPA oil drain plug gasket (copper washer) - early 4bt

    Cummins Tech Section
    My 1986 4bt was dripping from the oil drain plug. I found a skinny copper washer. NAPA sells a more substantial copper washer for under $2. It is thicker and wider. NAPA # NOE 7043007. NOTE: 4bt parts can often be found by searching for 1990 Dodge D150 with the 5.9L diesel engine
