    best results with the head removed .

    but if you can't ,
    use a vacuum cleaner duct taped to the intake while it is BLOWING air
    crank the engine till the intake valve is open and the exhaust is closed .
    put grease on the supplied tap.
    then slowly tap the hole for the insert.
    the escaping air pushes loose chips out of the cylinder and the grease
    traps the rest .

    de-grease the new hole before using the inserts .

    if the head is off , you can skip the blower and grease
    then stake the insert from the cylinder side to prevent it from walking out

    Very bad quality. The tool stripped itself and litterally destroyed instead of making the strips. Useless, will have to buy an other one. Would not recommend

    The taper on the reamer is too fine and you will have to work hard to get it reamed + threaded. I'd recommend putting it in your drill press (non-operating) so that you can keep constant pressure behind this. You could also try grinding more of a taper into the nose of the reamer. If you try to your your hole out *just a little bit* to make clearance for the reamer, then you will have already over shot the desired diameter for threading.

    Once that was all sorted, the inserts were great.

    threads stripped and failed on an aluminum block not even after 1 use

    agree to spend more to get a better product that works.
