yep what edward says is true
the crank and oil pump markers are clearly marked on the case with raised indicators, the only one thats hard to find is the cam marker, it is marked on the timing cover, that one is located at about the 9 oclock position about where the seam is where the head meets the engine block. Just look closely and you will see it. As for the indicators on the gears the cam gear has a dot etched into the gear, that one is light so look carefully, same for the oil pump gear, it has a dot on it etched into it but also has a defeflector washer behind the gear with a knotch cut out of it aligned with the dot on the gear.

also even when you get all the marks lined up and get the belt on take extra care to watch the alignment marks after you tighten up the idler pulley, it is very easy to get off one tooth. Yes... even a single tooth will make the engine run poorly, so make sure it is on the marks after you're done.
I have also seen many techs try to skip the oil pump gear timing mark but trust me... it makes a difference, if you do not line up that marker the engine will have a vibration in it.
