I recently purchased a 955l track loader to use on the farm. After I have been using it the radiator runs low on water and puts it in the oil. The oil is nasty gray and thicker. I pulled the vavle cover and dropped the pan today, the motor is full of the gray sluge like oil. I have a bad feeling it's probably the liners, but is there a possibilty that it could be an oil cooler or water pump. What would be the proper way of "process of limination". And if it is a liner issue do you have to pull the motor completely out? I see there is a piece of steel that covers the back quarter of the motor and the cross support is in the way to get the bolts out. Could use a little help on this. And the motor is a cat d330 from what I can tell.
