My problem was not fixed. Refer to post “Head bolt torque, take a good look at this” for my original problem. Well after removing the rear head, cleaning up things and reassembling the motor, I still have the same problem of water to oil and oil to water transfer. And pretty sure I still have a dead #6 cylinder. You can keep a finger on #6’s exhaust runner after engine start when you can even think of even getting near any other cylinder’s exhaust runner. Some pics are attached of the reassembly. The last one shows the crud I had on the upper end. I flushed the coolant system 4 times and changed the oil after reassembly. All you Cummins guys chime in on this one. Maybe I have two problems, a bad # 6 injector and the oil and water mix problem somewhere else. Cracked #6 liner causing both problems? Bad oil cooler? Would like to investigate all outside repair options first before dropping the oil pan and popping out liners. Any easy way to pull the non top stop injectors without the special Cummins tool? This truck was driven home 75 miles from the GL yard at Ft Carson, CO back in February. The coolant was nice and bright green then, oil free. No sign in the rocker box of water in the oil. I could tell the engine wasn’t firing quite right from day one of the pickup. Engine has never run over 190 degrees water temp and lowest oil pressure at idle even with contaminated oil is about 35 PSI. Could sitting for a long period of time dry out the liner O rings? Need ideas where this two way transfer is taking place. Dam thing still starts right up. Help!! SOS!! MAYDAY!!
