    Ditto on most narrowly spaced valve springscylinder head areas


    Posted by a reviewer on Amazon

    Set cylinder at top dead center so im not fighting a cam lobe and piston is up in case valve tries to drop


    Posted by a reviewer on Amazon

    Others have stated that the handle was hard to turn or was hard on the hands


    Posted by a reviewer on Amazon

    Their valve springs must be much harder to compress than mine

    I had all 16 valve seals changed in about 3 hours using this tool for my first time

    The attachments were bent and one was cracked
