I'm in the middle of changing out the old compressor because it was leaking pretty good.
I bought a 'new' (not a reman) Visteon FS-10 compressor that supposedly has oil in it already. I went to empty it out to see how much was in it, but nothing came out even turning it etc...!?
I tried the same thing with the old compressor and only got less than 1/2 oz out...
Any ideas if I should add the correct amount?

Besides replacing the compressor, will you be replacing the accum/dryer? Will you be flushing out the lines, condenser, evaporator etc?
I'm flushing the lines except for the one with the muffler, new accum/drier + liquid line w/orifice...

I didn't do the evaporator or condensor as they're buried in the car and I didn't want to risk not being able to get any solvent out (mineral spirits.) I did all the other lines and they were clean. The oil that came out was clean, no debris or black at all...
The old compressor never failed, it was just leaking. The old owners of the car replaced the condensor, accum/drier, and liquid line last year before I got the car just to have the mechanic tell them it was the compressor leaking. I'm replacing this stuff and the compressor though because it's been leaking so long though...
I'm just concerned about putting to much oil in it as I can't get anything out of either compressor (well, less than 1/2 oz out of the old one!)

I would add back four or five ounces if the compressor was dry..Add about an ounce or two to the compressor, turn it to get everything wet inside, then add the rest to the accumulator...it's a "guess" since you didn't flush all the componants though..

Most of the oil would be in the accum/drier and compressor right?
The system holds 7 oz according to my manual.
So you think 2 oz would be still in there?
So I'm not doing anything wrong in the fact I'm not getting anything out of either compressor???

No, oil should pour out if it was filled..The condenser and evap will hold at least three ounces of oil between them..But again, thats a guess as to how much is exactly in there.....

Sounds good, thank you! I rather a good guess from someone thats educated in this area, than me that is a first timer! I hope it all works out. What you say is along the same lines as the manual I have, I just wanted to be sure and hearing from someone that knows makes me feel much more secure in doing this job.
Thanks greatly for all the advice here and in my other posts

It's all working now! Thank you greatly Chick, I would not have tried this without your help and advice! I got it finished on the 10th, charged etc the next day at a friends place, but have been working so not been able to post up, sorry. It's great to have nice cold air again! I don't remember the pressures when we were finished, but I ended up flushing pretty well everything but the line with the muffler (it was ~$400 to replace, ouch...) and the evap in the dash as I wasn't sure if I could do it correctly installed. I added 6oz oil and, we vacuumed it down for 15min to check for leaks, then vacuumed it another hour, charged it up with 2.2lbs like it called for and its been working great since!
Thank you!

An update question if anyone could help please?
What are the signs of too little or too much oil in the system?
I ask because every once in a while when the compressor engages it will make almost a lugging noise from the compressor. I don't know how to best describe the noise, in my opinion I think it has too much oil, but I'm not very knowledgeable with a/c stuff?! I'm putting the car away for the winter in the next few weeks most likely, so wanted to see if I could or should worry about this? It is still cooling very well...

How much oil is in the system?
-------------------------
I flushed the lines with mineral spirits ('popped' them repeatedly with cleaner and dried for about 10 minutes with compressed air), and blew out the condenser and evap till nothing came out anymore (about 10 minutes each too, popped these as well to get as much as I could out), new liquid line with orifice, new compressor and accum/drier, and new orings on whole system...
The system calls for 7oz, and I replaced 6 as I didn't flush the evap and condenser totally/properly... I split up the charge between the compressor and accum/drier.

I have the car back home for the summer, it is still making the noise like it's lugging or venting or something (it's like a loud squelch.) It still seems to be cooling fine.
I did notice however it only does it if the car has sat for a while. I also noticed an oily residue on the clutch/pulley and behind it. I doesn't look like oil from the ac though, and there is nothing else near it that might be leaking oil. Would washing it down real good with degreaser hurt the compressor so I can keep an eye on it to see where this oil is coming from?

It can be a few ounces overfilled with oil and still work ok. When I bought my new Jeep it never cooled well on a really hot day so we began investigating why. I evacuated the system and got a full 8oz of oil out of it when I drained the AC machine.
The Orifice tube was drenched with oil. I pulled the dryer off and got a full qt of oil out of it! Got about a good 10 oz out of the rest of the system by flushing.
This was on a brand new Jeep that I bought as soon as it hit the lot! I watched it come off the truck so it left the factory like that. Why? Who knows? Maybe they had trouble with it and were messing around trying to make it work?
Anyway since then I got it working good. It's got a couple of extra ounces of oil in it.
That sounds like a ton of oil in your Jeep! I worked at a Lincoln dealer, and a BMW dealer at different points and it was amazing what they would ship us at times!
So this oil is probably coming from something else then and has gotten on the clutch I guess? Will degreaser hurt the clutch?
In the past year, I've changed the alternator (well two summers ago), AC compressor, and the idler/tensioner/belt last fall. I'll have to wash it down and see where it's coming from. The front cover is dry though, thats why I'm having trouble finding anything.
Thanks

I degreased and brake cleaned the entire front cover the other day including the pulleys and ac comp with the belt off. I let it dry real good with aide of an air hose. Replaced the belt with a new one so there was no oil on it, and it's not making the noise any more!!! It still makes a lil light belch once in a while if its been sitting, but so far so good I may take the belt off and clean it again to be sure. I'll keep an eye on it to see if I can figure out where the oil came from, but I was thinking while doing it that it may have been from the guys that did the undercoating, as they drenched the car pretty good...
