    hi i have a m111 ce coupe 1997 its a 220

    to day a friend and i were working on this car when we had tdc mark lined up

    and then took the rocker off the cams were out so when we lined up the cams were the bolt go trough to the cam from the head the tdc was out a fair bit looking at it about 1 inch

    i took the bolts out from the cams for the timing set up and put a screw driver in piston 1 and marked it then turned the crank and lined up the tdc and yes the screw driver moved up about 5 mill

    i have never seen a double chain slip or be out so much the guy driving the car said nothing about it being heavy on fuel or under powered and in a emission test done only last week it passed

    has any one come on this before just said i would ask

    we are going to reset it tomorrow now re-line the exhaust and inlet cam to the correct setting with tdc

    Please take note of reply on other thread.

    For other readers, NEVER assume that timing marks are supposed to align at TDC.

    If its a M111 engine then the timing is right when the engine is at 25 - 30 degrees after tdc
