    Yea thats correct, setting the crank pulley at 0 timing mark will set No1 and No6 piston at tdc but to not confuse you Just work your way along 1-6

    Please correct me if I am wrong but setting the crank pulley at 0 timing mark will either set number 1 and number 6 pistons at top dead centre OR at bottom dead centre. That is where the screw driver comes in with the crank pulley timing mark at 0 put the screw driver in number one spark plug hole and make sure the piston is at TDC not BDC

    and if it is at BDC? Do you rotate the crank one full revolution more and then it'll be at TDC, or do you just turn the crank until no1 is at TDC and forget about what the crank timing mark says?

    If it is BDC turn the crank 1 full turn and line up the timing mark again and it will be TDC

    Actually I am typing before engaging my brain d&d was correct with the crank pulley timing mark lined up number 1 cylinder WILL always be at TDC but you also need to ensure the cam timing marks are lined up if not you will need to rotate the crank 360 degrees

    You'll find it in the Members only downloads area under Engines.

    Hope that's ok with everyone.
    Top man. I was just pondering how best to print this myself. You've saved me a lot of effort. Thanks

    In the interest of helping out here, I suggest checking the seal part numbers, my info suggest whats written here is the wrong way round and could end in trouble, I might well be wrong but please check.

    IIRC the part number has been updated now and they're all the same now anyways.

    As has been said earlier in the thread i used to do these for around 400 plus parts and now i am at AFR this will still be the price, we don't use string however we keep the valves shut using compressed air
    "I came into this world screaming and covered in someone else's blood... I have no problem going out the same way...."
