HOW TO: Check camshaft timing
KEY:
White dots = The small dimples on the cam gears.
Yellow dots = Roll pins through the links holding the chain together.
Red lines = Where the respective dimple on the cam gear should "pass through" the chain. This line demonstrates how many links/roll pins etc... should be in between each dimple on the cam gear.
Green circles = The keyhole on the cam gear where the dowel pin on each cam will fit into. Note the orientation.

This is with the engine at TDC (Top-Dead-Center) for Cylinder # 1. It is not at TRUE TDC because the chain links are in a different part, but for all educational purposes, it will look like this with Cylinder #1 at TDC.
If you have a pulley that is aftermarket, check which hash marks represent what numbers of timing. (Note: Sometimes the stock pulley can separate and give false readings.
On the B14 OEM pulley, the 2nd hash mark from the left represents 0* or TDC at the crank.
Once again, you want the pin that is stick out from the block to be right on top of the 0 degree mark.
