    Why would compression be different with engine running as opposed to just cranking it over? Anybody

    Because there is what's called Dynamic compression(Running)
    and Static compression(not running).
    When an engin is running allot of varyables can and do change values from a non runing engine. Temp. is just
    one of them.
