Connect a set of manifold gauges to it to see what your line pressures are. You may not have a leak, it could be that the pressure on the low side is just too high. Does the condensor fan kick on when the AC is on? Are the fins bent on the condensor core?

Or it could be a leak, but you should at least check before jumping to conclusions..
