You need to immediately drain the oil to get rid of the water in the oil. Has the oil and water emulsified to a beige color with a chalky feel? If so you will need to flush the engine to get the "sludge" out of the engine. As Tim suggested, the best option is to pull the pan to clean it out. I used a cleaning gun with a diesel and ATF solution to clean the top and bottom end to get all the mixture out. After getting most of the oil mixture flushed out, I filled it up with diesel and started it up for about 20-30 seconds to flush the oil journals. Drained the diesel and added fresh cheap oil and a new filter and ran that for a few minutes at idle and drained it. Now I replaced the water pump with a John Deere Reman which in the long run is about as cheap as buying all the parts and having JD dealership doing it. Dealership would only give me a 90 day warranty if they did the work. Cost me about 450-475 dollars to replace the water pump as I put on all new hoses, thermostats, etc. Once done with the pump install I did a pressure check for leaks and then repeated the new oil and filter again and ran for 10-15 minutes at idle and drained again. Will change oil again once hay season starts. Tractors runs great with normal oil pressure and proper temps so it looks like I got it fixed before it did any damage. Lots of money for pump,oil and filters but it sure beats an engine change. [Reply]   [No Email]
