water in oil
Puzackly. It might be normal for your situation. I would remove the valve covers and drain plug and dump diesel fuel all over the heads until it ran clean out of the drain plug. let it drain out real good put the plug back in and a new oil and filter and see what happens. Oil is like a sponge if you don't heat it up and burn all the contamanents out. It will just keep gettin worse and worse if it's not heated beyond a certain temp on a regular basis. I bet that's all it is. Certainly worth spendin a few bucks on to find out.
