W114 a/c compressor noise

I filled up the a/c with R12a and it was working for 2-3 days and now is completely empty
When it was working I could feel significant resistance from the clutch almost like towing something and the a/c compressor was making noise louder than the engine

Since the system is empty now the clutch is not engaging

I can not see visual leaks and wondering what is the usual place for leaks on these systems?

Here is a you tube video and hope you can hear the noise coming from the compressor

Those York "Thumpers" were always noisy. Yours appears to noisier than most so I'd guess it's a bad compressor. Yank that piece of crap off and replace it with a Sanden. You need an adapter plate to mount the rotary style compressor, some new hose ends and probably have to re-work the drive belt system but you'll be miles ahead in the long run.

Throw a can of dye in to track the leak BEFORE you change the compressor. The odds are it is the old York leaking but it's easier to figure out what all you'll need before you spend the money on the new unit. It'll just piss you off to do all the work only to find out you have a leaking condenser.

Thank you
Is there specific sanden model that would work with this car?

you could always use a new york [ original ] , use the right kind of oil and 134a .new drier .see if you can splice a filter in the low side hose , napa has them .it will keep junk from been sucked in and running the new compressor .slightly under charge it is easier on system , and still cool well .
