Well the 2.5 engine is a fairly easy engine to work on, especially in a s10, plenty of space. you might as well go ahead and change it, the gaskets is probably about 20 bucks and it would take maybe half an hour to change. If you really want to check it that's pretty easy. just turn the truck on and let it run, once the engine is warm grab some starter fluid, be very careful and spray the base of the intake, the carb and any place you believe it can be leaking. If its leaking it will change the engine sound(rpm's will jump up) once you find the leak, get some silicone or other type of sealer and blob it on the seam that is leaking, and try the starter fluid again and if it stops, you know you found th leak, so do what you got to do and fix it.
