The backhoe has ~3400 hours on it according to the hour meter. I don't know much about the history of it. I bought it from a guy on CL and he'd only had it about a year, but I could tell it hadn't been maintained like it should've been. I've been working to get everything fixed to bring it back up to being a reliable work horse for around-the-farm use, but I've encountered a problem and wanted to get some feedback from the greater JD community.
This past weekend I changed all of the fluids and flushed the radiator. The oil that came out of it was thick and black, almost like latex paint. I put Rotella 15w40 back in it with JD Hy-Guard hydraulic fluid. I also put a new temp guage in since the old one was broken. The problem that I'm having is now oil starts pouring out of the dipstick tube once it gets up to operating temperature. It's a pretty good stream too. It's not overfilled, I'm sure because I've checked that numerous times. Also, I'm losing a lot of water/coolant from the ventilator tube that comes out of the valve cover and goes down beside the block. It comes out as steam - enough to burn your hand. At first I thought that was just an exhaust leak but it wasn't.
I called the JD dealership here and spoke with a parts guy about the oil flowing out of the dipstick and the coolant loss out of the vent tube and he told me that it needed to be re-sleeved and the issue was caused by significant blow by. He also asked if the oil coming out of the dipstick tube looked like coffee with creamer in it, which it does - to which he said that was water in the oil. In my limited experience this all points to either a blown head gasket or a cracked head?
Has anybody seen this before or had the same experience? Any way to verify if it's one or the other? Thanks in advance!
