The valves are not supposed to be leaking when you pull the caps off. Spray the valve with some soap water to see if it is bubbling. In that is the case you should have a shop recover the remaining amount from the system, replace the valves, vacuum the system for 30 minutes then charge to the proper level. It is near impossible to get the correct amount of refrigerant in there as the whole system only holds 0.98 lbs of 134a and doesn't cool properly with too much or too little of it.
