I can get in there and pressure wash. I was going to do that anyway, when it was covered with dust. Now the dust is gone, and replaced by oil. As I wrote, I cautiously ran it a little with the cab raised to see if I could see where the oil was coming from, and I couldn't. If it's not really much of a leak, I might just keep an eye on it for while, since I need the machine in the next two weeks. After that, I can spend more time diagnosing the problem. Another question on this machine, will I get a code or shutdown if the oil gets too low? I have the electronic display, and I know I get a low oil pressure alarm. I set the display to vitals, and watch the charge pressure and the hydraulic oil temp, and they are always fine. What damage will I do if it gets too low?
