Just got a 743 Bobcat at a auction. 2800 hrs. Looked very clean and well cared for. Starter a little glitchy, but runs very strong, sounds great and good hydraulics. No exterior leaks on engine and looks clean. I have not run it other than getting it home. I then noticed the coolant was down so I filled, next thing I know I have oily/water mud coming out of the oil over flow and dip stick. So I know this probably means $$ and a bad head gacket, head or cracked block. Where should I start and how do I go about deteremining what it is? I am not that familar with Bobcats or diesals. Thank you for any help.
