It's history. I was able to check it out saturday. It sat for a couple of days with water in the cooling system. It is now in the crankcase and the cylinders. The compression is between 15 and 30 lbs and still has the clank. The owner is ordering another engine. It's amazing that a $10 part failure can take out a $1700 engine but stuff happens.
