Over the weekend I adjusted the valves on an M189 engine. M189 has a big harmonic balancer on the front of the engine with 6 mm holes drilled into it so turning the engine by hand is very easy using a couple of metal rods.

I turned the engine so the cam on the first valve was pointing opposite the rocker arm. Then I adjusted that valve to its specification (I think .10 for intake, .25 for exhaust but I might have those switched). Then I turned the engine so the next valve that was almost pointing opposite its rocker was in position and adjusted that valve. etc. So I turned the engine 12 times to adjust 12 valves.

So in the attached picture, the next engine turn would be to adjust the 3rd cam into position, then the next turn would be to adjust the 1st cam into position, then the next turn would be to adjust the 6th cam into position, etc.

Did I do that right?
As pictured, yes those would be the next two valves.

Adjusting each valve with the lobe at 180 to the follower will ensure that the cam is on its base circle, although, as noted above, not entirely necessary.
