    I don't know for sure- but on all BMW engines I've ever worked on, there is a small arrow in the piston top that should point towards the front of the car when installed properly. Do yours have this??

    Also, I would ASSume that the cutout is for the larger of the intake or exhaust valves- isn't that the intake in this case??
