Help required for an OS90FS. That's an older version: Front glow plug (dangerous!) and back cam and push rods.
What are the references to properly time the valve cams.

Easy way to set it:
Rotate the crank until the piston is at TDC. Set the cam so that the lobes are equally spaced on either side of a vertical line. Doesn't matter if they are at the top or bottom. One tooth off will be quite noticeable.
