Ty: If you have the '70' Diesel owner's manual, OMR2032M, the crankcase flushing is covered under 120 hour service on page 73 for the diesel engine, and under 500 hour service for the pony on page 75. For the Diesel it reads: "FLUSHING THE CRANKCASE" During a period of several months of operation, sludge may form in the crankcase, and other foreign matter may collect on the engine parts. Make it a practice to flush the crankcase thoroughly at regular periods. Distillate or Kerosene are good flushing and cleaning agents. After draining the crankcase and removing old oil filter element, replace oil filter cap, pour 1 gallon of flushing agent into the crankcase, run the engine a few minutes, then drain out the flushing agent. For the Pony: SERVICING CRANKING ENGINE CRANKCASE Loosen plug screw and pull it out as far as possible. The oil will drain into the diesel engine crankcase; therefore the operation should be performed before draining the diesel engine oil. Replace plug and pour 1 quart of flushing oil into crankcase. Start engine and run it for 2 or 3 minutes. Drain flushing oil, replace drain plug, and fill crankcase with good quality new oil to full mark on dip stick. When checking oil level on dip dtick, filler cap must be screwed down tight. Crankcase capacity is one quart. Since we didn't often have Kerosene around, I always used #2 diesel fuel, and it seemed to clean very well. It really seemed to work on this old '70' of mine. After 7,000 hours, it had virtually no cam wear, and very little crank pin wear. The crankcase was very, very, clean. I use this method on most all my engines. My pride and joy is my '88 Plymouth Voyage that I bought new, and now I only drive when I'm home on weekends. It just turned 278,000 (I'm trying for 300,000), and has never had the valve covers off. Hope this helps ! Frank-in-Tallahassee
