So it's not the head gasket? And you are still losing coolant? Well, okay, you will have to find how the water is getting into the rocker, and whether it's your lost coolant or plain water. IDK, possibly an intake manifold leak?
Even though the oil looks clean, the water and gunge in the rocker area will drain into the sump and contaminate the oil. If it's not the coolant, run the engine until it is hot, then give it a few minutes for the oil and water to drain down from top of the engine into the oil sump. Then change the oil and oil filter. Good luck, hope you find the problem.

Have you changed the water filter?

You may have blown the internal fuse. Remove side cover, locate the circuit board and fuse, replace and reseal reinstall side cover.

you need to replace the water solenoid valve panel located where the water hoses hook up to the washer

Diesel engines are more prone to this problem, chek the seals on the guel fill neck to make sure there not leaking water in to the tank, other then that try adding an additive such as MDR Desiel warter zorb, its like $18.00 and see if that mitigates the problem. Fuel filter is recomended to be changed I belive every 70,000 miles on the Desiels.

Locate thehose on the left side of the car next to the air filter, trace this hose to where it enters the motor. Loosen the two bolts hlding the thermostat, place a mark on top of the thermostat before removing to ensure you replace it in the same manner in which it was removed. Take the thermostat place the thermostat in some water and boil the warter, if the thermostat opens, then check the temp sending unit located next to the thermostat.
