Default A/C Compressor blowing bubbles.

So, my A/C system doesn't have any freon in it, and supposedly the guy was working on all the A/C system, and just needed to put freon in it to get it running.

I took a paper clip and jumped the plug (like I was told to do) to see if the clutch would engage, and it does. I had just sprayed the motor down to clean it right before doing this, and when the clutch engaged, I saw small bubbles coming from the compressor (where the red arrow is in the picture)

My question is will freon come out from here if I fill it up? Or is it caused from something else?

I don't want to waste money on freon if it's just going to come back out.

Looks like that seal is gone and the compressor needs replacing.

That's what I was afraid of. Another $220. I need a job.

Is that a mating surface for two parts? If so, maybe it can be tightened.

There is definitely a seem right there. I'll look in a bit to see if there is a way to tighten it up, but my mechanic friend says that I'll probably have to replace it.

Hi, I'm new here, but usually a compressor leaks around a seal that the shaft passes through. The arrow in your photo is not really pointing to this area. A fairly reliable sign on a used vehicle is an oil sling pattern above the compressor on the hood insulation.
Granted this is not the only place for a leak, but if you have one in the compressor area and it is not where the hose connector fastens to the compressor, the shaft seal is the likely place. It is typically hard to find because it only leaks when the compressor is engaged and turning. I HATE to put die in a system but it is usually the most reliable indicator in vehicles.
