timing marks on cam gears

Ecoli is right. To see if the motor is "in time", make sure the two inner cam marks align with the top of the head. Then check the timing mark on the harmonic balancer. It should coincide with the top mark on the timing cover. 1G, 2G. Doesn't matter.

Pay no attention to the outer marks on the cams. They are there only to confuse people!
