My B7100d sprung a leek. I'm lossing about three quarters of a quart every hour. It seems to be coming from the front of the oil pan. I have a plow on. Its difficult to tell for sure. My repair manual doesnt show the bottem of the engine or include anything on the oil pan. I was hoping I could get some pointers before I dig in. If any one has a owners manual for this machine I'd like to hear from ya.
