Question about 1987 Nissan Pickup
You think you didn't move anything...chances are something moved. Don't run the engine. Get a chilton or haynes manual and find the proper index locations for the pulleys and re-set the cam timing.
Since the engine still runs, you may be able to find the index marks because you have to be fairly close in order for it to run. Even a 1/16" variation will throw off the phasing between the cam and crank enough to make it run poorly. On most injected engines it will also change when the injectors fire as well. On many engines, being off can cause the valves to strike the pistons, then you'd need to replace the valves....that's why I mentioned not running it...no idea how close you are to doing that.
Marking on the belt shouldn't make a difference if you have the cam and crank positioned correctly but they may use it as a measurement for setup. I've never seen that but it's possible. (I don't have book on yours)
