m104: intake cam timer
 

Friends, I have a problema, I have a m104 disarmed, I am putting the timing chain and I do not know how is mounted the gear of the intake cam (intake cam timer), the camshafts are aligned, with the 4mm marks, and the crankshaft mark is 15 degrees.
i dont know how is the correct position of intake cam gear, turned clockwise?

Timing is set at top dead center 0 degrees at crank pointer, next take intake timing advancer gear and without chain on gear rotate outer part to the right, next drape chain on gear and install exhaust cam, note small holes in rear of intake and exhaust gear should align slightly above flat surface of head , after everthing is installed rotate and recheck timing marks with tensioner in place
