    Compression testing

    Hey Guys

    Im about to do compression testing on my wifes ski. (155hp 4-tec)
    Ive had different opinions on actually doing it. Some say to test it with the motor cold and some say to test it after the motor has warmed up to operating temperature.
    I would have thought it should be done after the motor had been taken up to normal operating temp.
    Any advice or thoughts on this subject would be appreciated guys.

    Thanks in advance

    Regards
    Alex..

    I have always been told not to remove the plugs when the head is hot, you will screw up the plug threads so I check it cold also.
