There should be only one way the gear goes as it should set on a key on the cam.

The I is for intake and the E is for Exhaust. It is a reference for which stroke the engine is on at that top mark. The compression stroke is the I and overlap is the E.

They each have a notch, though, both exactly the same and will fit on either way, but in an effort not to ruin the engine. Trying to find which notch the pin should go on to the cam pulley to the cam

You have to determine the position of the cam, whether it is on compression or valve over lap. You need someone familiar with camshafts, after you remove the valve cover, to tell you which stroke it is on.

Once again, the notch on the gear for the timing marks are not 180 apart. If you use the worng one, you will time the motor wrong and if it is an interference motor, you could bend valves. The position of the cam must be at tdc compression and the mark should be straight up. I mean the notch on the gear by the teeth.

Not inconvience. Trying to make sure you put it on correctly so the car runs good and not cause other issues.
