What is the most common thing for the Z134 to be getting water in oil? I rebuilt it 4-5 yrs ago everything new and only have 16 hrs since rebuild. Been on drives and to shows. After letting all my tractors run and checking everything today I found the radiator low. I have several Z134 and this is the first to give problem. Next project after weather cool's down. Hot in Texas.
 
I drained oil and added new oil and ran for several minutes and drained. The antifreeze is still full in radiator. I'm letting it set over-night to see what is coming out before taking engine down. It's a TO35.
 
I'd pull the oil pan then apply 4 to 8 lbs. of air pressure to the block drain on the right side and watch for drips around the cylinders. Mine had drips which turned out to be rib cracks in the bottom near the o rings.
 
Yeah the block is toast. Dieseltech said if it's cracked around bottom where orings go it's toast. Stitching requires the area where the crack is to be at least 3/16th wide. The ribs are wide enough but center rib would be hard to drill.
