This story continues. I have bigtime water intrusion into the oil and oil intrusion into the water on my 1972 Cummnins powered M818. See "Help needed!! 250 Cummins loose headbolt part two" posted 26 Jun 08. I pressurized the coolant system as someone suggested with the oil pan still on. Made an adapter with fittings on hand with a Shraeder valve on one end screwed into the water feed pipe on top of the head (see pics). I used o a clip on air chuck and about 10 PSI. I had drained the oil before hand and water started ti dribble out. This engine had a dead #6 cylinder identified by IR thermometer readings. So the focus has been on that cylinder. When I loosened the injector hold down clamp on #6, air started to escape. Looks like a cylinder liner problem for sure. Next step is to drop the oil pan and pressurize the coolant system again and see where the water is dripping down from. Wanted to pass on that these non top stop injectors come very easy with a crowsfoot pry bar. The one I used is from NAPA and has an adjustable angle which reallly helped. Will update after oil pan drop.
