D15 engine with water in the pan

MMZAck · Aug 9, 2018

I transplanted a G160 from a D15 tractor into my D12 for pulling. I had already had the tractor running last week but before I fired it up last night I decided to fill the radiator with water before a test drive. To my surprise, it took a lot of water as I filled it until I notice water overflowing out of the dipstick hole. All coolant I put into the radiator went straight into the crankcase. What causes this? The engine has been a mess as I bought it sight unseen and have had to fix a few other things. This is just the latest issue. I am thinking of dropping the pan and running water through the radiator to see where it's coming into the crankcase. Where ever it's getting in, it's flowing pretty freely. Thoughts?

Had a WD that froze, split the block lengthwise through the lower sleeve bores and through the center main saddle too...

You might get lucky by removing the valve cover and seeing if one of the freeze plugs isn't pushed up and out of it's hole.....maybe.

Check under the rocker arms for core plugs to be rusted out or just gone first.
If that is not where the water is getting thru drop the pan and see what sleeve it is getting around. If the water is not coming from around a sleeve then it is time to remove the head and see what for gasket condition you have.
