anyway use a 27mm socket to turn the cam shaft.

you won't able to see the marker as it is cram in there, that's why I use a video recorder on my phone to record it and I suggest you do the same until it is at the marker. The marker is at 11 second mark of the video. that marker is next to the 3 screws on the right side (that line thingy)

it is REALLY tight so becareful.
