I like your videos, but the arrows on the camshaft sprockets are used only for setting the valve lash on the intake and exhaust valves (the arrows point to 12 oclock, 3 oclock, 6 oclock, and 9 oclock to get top dead center for pistons 1, 3, 2, 4 repectively.) There are notches on the outer rim of the camshaft sprockets that are used for alignment of the camshafts when installing the timing belt, and are not in the same location as the arrows. The timing belt alignment marks are shown clearly here, between 10:30 and 11:00: kzbin.info/www/bejne/paTFnWiDq6Z3fJI Thanks -

Mongo thank you and Mongo appreciate the detailed feedback. Subaru engines, as you pry know have many different layouts and options through the years. This engine model, year and style has 2 sets of marks on the cam and crank. Arrows or small notches. (crank has a rectangle instead of a notch) If you set the timing one way and spin the crank to the other set of marks, they will also be aligned. For this style Mongo uses the arrows because they are much easier to see. You are correct that it is best to always use the small notches (best practice), especially on an interference engine. The biggest fail of a Subaru engine is having 2 sets of marks on the gears/sprockets, because it creates so much un needed confusion. Mongo probably should have explained all of this in the video.
