My compressor on my car is leaking oil and I need to replace it. Does anyone know what the difference is between the AC Delco 15-21697A and the AC Delco 15-21697? 15-21697 is about $8 more expensive on Rockauto.com.

Is it worth the extra $30 or so on Amazon to get the oem over the profesional version?

Should I also replace any other components or orings while I have it apart? I'll also order a new drier and orifice tube.

I do not know how the OEM and Pro versions compare in this case; I do know that the Delco OEM tends to be better than the Professional version across the product lines.

You may want to flush the system if the old compressor fragged when it failed. You must get a new dryer and orifice valve, both are usually done in by compressor failure, or worn out when compressor wears out. Replacement orings should come with the parts you are R&Ring, and you definitely should use them if only because in applications having thermal cycling it usually does not take long at all for orings of whatever composition to take on a Set.

I think this was broached (what to replace) earlier in this thread. And I think there i posted that you should/need to get the Variable orifice valve.

Hopefully I caught it in time as the air conditioning was working before I saw the oil puddle and no weird noises coming from it either. I am planning on getting the variable orifice valve. Is there any reason to change the valve core or o rings for the condensor while it is apart or is it a case of if it ain't broke don't fix it?

When you depressurize an AC system, expect to replace o-rings in order to prevent stupid leaks.

Valve core -- you don't want to leave dirt or compressor fragments in the system. Do you really want to agonize over an inexpensive part which, if it is dirty beneath, will ruin the rest of your install?

Are you sure the leak is from the compressor? I had mine dripping and it ended up being the high pressure line in front of the compressor had cracked.

Also, if you (or anyone else) ends up needing a new evaporator core i have a brand new one that i never installed (since i found my leak elsewhere).

That's a good point about the line could be leaking. I just took a look and the lines seem to be fine and somewhat clean with no oil residue. It hasn't leaked any oil this week, but then again I haven't driven it much this week either. The air does still blow cold so hopefully it was caught in time before filling the system up with debris.

So I have been having a knocking noise from my compressor/clutch. Only happens at idle/decel low rpms for some reason. If I give it gas at all the noise stops. Been doing it for about 2 years now and the A/C has always worked well.
...until this week. Checked it out with a manifold gauge and it shows 30psi low side and 110psi high side (80outside temp). So looks like the compressor isn't doing it's job. Oddly enough the noise is quieter than before too.
So a new clutch assembly is $75 and a new compressor with clutch is $170. Not a huge difference but the labor for the two jobs is vastly different.
I pulled the belt and the pulley has no wobble to it and when turning the clutch and pulley the compressor turns easily and makes no noise.
My theory is the magnet has let go (maybe always has been and that's what the noise was?), but I still get a click when the ac kicks in.
Any thoughts?

Ended up adding some R134a to my system until the low side was at 40, high side came up to around 180 which is closer to where it should be. Blowing cold again. False alarm, must just have a small leak somewhere.
Now if i could just figure out which blender door controls driver side air temp..

My understanding is old AC hoses "weep," you can refill every so often,or replace them.  I've had my system recharged twice since I bought the car in 2000, however past 6 years or so I found that topping it off about every 2 years) is fine.  I use a consumer-grade can of refrigerant (NO goop/sealer/etc) and a consumer-grade valve with a gauge.  Because the ports are differently sized, the contraption only fits the port it's supposed to go on, on the Riv.

PS - don't overfill it. More is not better.
