Do you guys think its the sleeve O ring,s leaking?Took the side covers off and was going to pull a piston and sleeve ,darn cotter pin broke on castle nut and i cant get it out .Not enough room for my big hands.Am i going about this the right way?
 
I just went through this on my DO, hopefully you won't find the cracked block that I did. Try to shine a flashlight up into the side covers. If it's leaking from the orings, you should see some green around the base of the sleeves. If not, the leak is somewhere else.

As for the broken cotter pin, try turning the nut slightly. The hole for the pin runs straight front to back and if the castle isn't perfectly lined up the pin won't slide. I broke a couple cotters before I figured this out.

Good luck.
 
How much water? I always prefer to try a chemical solution first. Block sealer might solve the problem,if the leak is small.
 
Pull the inspection plates on the oil pan and see if you can tell where the coolant is coming from. I had the problem ans it turned out to be hole in the sleeve, I could see the leak from the inspection plates. You can also tell if it's a oring.
