Then test with hand tool from crank that engine rotates freely and only to the normal rotating direction (clockwise).
I had same dilemma from the factory manual and took several times reading it to be certain how to get this done right...

It`s pretty straightforward if you think it over. In the boxer engine the opposing cylinders must be in the opposite stroke, i.e. if cylinder 1 is at intake, cylinder 4 must be at combustion - at cylinder 1 intake valves open while at cylinder 4 all valves are closed. This can easily be checked if you look into the ports, or just inspect the camshafts' position before you put the cover back on. To achieve this, the camshafts at the opposite banks must be off by 180 degrees, hence you turn the crank a complete revolution. It does not matter which bank you time first, the combustion will be determined by the camshaft position sensor.
