I've got to work on a JD 6068 engine in a car crusher tomorrow. It started blowing steam out of the blowby tube yesterday after startup.
It's got coolant in the oil now. It runs fine and doesn't smoke white or anything. I was planning on pulling the head to see if the head gasket blew or if the head was cracked, but I wanted to run it by the experts here to see if there was anything else to check before I did.
The scrap yard has had this thing for several years and it's been sitting for a couple of months. They had just started a new job with it. Started it up and idled it up and after about a minute or two it started doing this. Everyone from the crew to the manager says that it's never been hot or even blown a coolant hose.
One thing I did find on an internet search was to check the water pump weephole to make sure it wasn't stopped up and sending coolant into the crankcase. I don't even know if that's possible on this engine, but was gonna check when I get to it.
I do have the service manual for it and it's got a troubleshooting guide for coolant in oil, but just lists the common causes like cracked head, head gasket, liner protrusion, etc.
Thanks
