    good compression if a bearing is out?

    can compression still be good if a crank/rod bearing went out?

    my comp is:
    1: 126
    2: 125
    3: 124

    i know there was a BAD clanking inside when i idled it home a week ago,,ive spun the crank by hand and cant hear anything metal noise wise.....

    i havent had time to put it on the water since i did the comp test.. i know going out and running it is about all i can do..

    It will be and can be good until the bearing starts coming apart. Fragments will start ripping the cylinder to shreads eventually.

    IMO the compression could still be good if the crank bearings allow the rod to make a full stroke. Could the flywheel be loose maybe ? Makes a clanky noise when the nut is loose.

    thats what im thinking,, maybe the bearing is out but still allowing the piston to make a full stroke.....

    ive got the crank snout support in the stator cover, so no way the flywheel is loose..
