Mission Creep on a D-150

The key to Kilmat installation is to do it while it's HOT. Kitty and I installed it over a period of two days in the broiling summer heat. Was between 98-101 degrees. It went on easy, formed easy and stuck like who flung dung. We were real happy with it.

Did you ever find out what went wrong with the engine? What caused that whole fiasco? I'm just hoping that you don't duplicate it.
