Why do you think the compressor is OK? Do you see and hear it engage? Even if you do, how do you know it is actually compressing? Flow in the sight glass might indicate some sort of compressor function, but it will not tell you how many PSI is being put out. The only way to find out for sure is by hooking up a set of manifold gauges.

What makes you say this? Either there is a leak or there isn't. There's no in between. And the only way to find out for sure is with a sniffer or, to a lesser degree, with UV dye. Judging by your questions, you probably don't have either of these. Use of borrowed or rented manifold gauges is the cheapest and easiest way to at least determine if there is enough refrigerant in the system to allow the compressor to activate.
