Some good news:
First the cylinder bodies were all fine. They measured in spec and had no scaring and no signs of warping.
The better news is the cylinder and heads all passed their hardness tests. The minimum hardness of the heads is 85HB and the Cylinders 90HB.
The heads measured between 102-134 and the cylinders 108-118. The lowest values were for #1 head and #2 cylinder.
As expected the bolts were all loose from the overheat. This probably caused a good amount of the compression loss.
The valves need to be reworked and heads trued up.
At the time of the landing we believe there was about a half pint of coolant left in the system.
The best news is that the insurance will do a pay-out under the clause the gives benefits if reasonable, unexpected expenses are made to protect the airplane from harm. The precautionary landing and teardown inspection fit this, so they will be covering most of those costs and most of the re-installation. Not covered is repair work to the engine.
Right now it is looking that the 7-Oh-Fun will be back in action around the end of January.
