I’ve heard that injection pumps can leak into the oil... but unsure if that’s the issue.
Only other thing coming to mind is stuck or bad injector... but I feel I’d be able to hear/feel that..
I may crack the drain plug on the oil and see what the color is. The old owner had off-road diesel in it. Since I just changed the oil it might be tinted red if it’s fuel...
It’s not coolant bc it’s not milky
I don’t believe it’s hydraulic fluid since it has a slight diesel smell I feel... but if it turns out not diesel then it’d have to be that.
It’s definitely thinned since I changed the oil and I’ve only driven it 2 or 3 times since that for maybe 10 minutes after letting it idle for a minute...
It was mentioned that the short run time may have caused that? I don’t know enough about diesel to know if that could cause that.
Would the thinned oil cause it to leak from either the blow off hose off the top of the engine or possibly lower crank pulley area?
Do they make rebuild kits for the JD 770 injection pump?
