I have a 92 100s and recently the engine has started making a clicking noise, its no knock, but a much higher pitched sharp click. There are a few other 100s's at my school and a couple make the same noise, just much quieter. I am very young and dont really know alot about engines, anyone know if this a quick fix or is it a much more serious problem?

Check your oil level, and make sure you don't have a fram filter and if it's not too cold where you live use a little bit thicker oil.

if it is not the oil or cheap filter it is most likely the check valves in the head they are a very easy fix do a search and you will find loads of info on them check valves or oil return valves, one in each head and one in the block under the valley pan, but 10 to 1 it is the valves in the head, just remove valve cover, unscrew the valve screw in the new ones and you are done. acctually these valves are repairable, just for the heck of it I repaird mine after I replaced them, the bottom seat come out of the valve just pop it back in and squeeze tight.
