    Did you start it and bring it up to temp, or just crank it for the compression test after the oil soak. I expect Mike's right on checking gaskets, but it'll start with 5 of 8 above 120#, and if anything's gonna free up the rings on the other three it's running it and getting it hot.

    Another thought, since this happened from a fire, perhaps due to the method used to extinguish the fire, will insurance pay for replacing the engine?

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
