I finally made time to dis-assemble the engine. I did not find anything major problems.
I did find one of the red coolant seals had fallen apart. It was not in one piece. The outside of the seal had separated from the red portion of the seal.
I don't know if that would be enough to allow water to seep into the oil.
I also found that in two different places the old style corner seal springs had not been removed when the new type corner seal springs were installed. Again, I don't know if that would be a problem.
One of the oil control rings wasn't pressed completely into the rotor but that might have just happened when I removed the rotor. Seems like the oil seals would press into place after torquing down the tension bolts.
I checked the irons to see if they were warped but all three irons check out OK.
If these things did not account for the water in the oil and the smoking for 15 minutes, I am open for suggestions.
