For what its worth (and I'll be surprised if someone doesn't have a go) but I run around for 5 months with my new compressor in before I recently got it regassed. I had every intention of getting it done straight after installing the compressor, however life had other ideas for me and it got put on the back burner until the weather started warming up[bighmmm]. The D3 really holds the heat in with no working A/CQuote:

So Im a bit over half way through repair in just one day, have replaced the condenser and got the old pump out.
Im posting all my photos and notes in this thread: https://www.aulro.com/afvb/l320-rang...ml#post3176031
I have some questions about oil, I will call local AC guy when open next to discuss and likely get some more oil.
I drained the old pump and only got 40ml oil (though some was spilt, maybe 5-10ml) but it seems plenty as likely leaked with gas.
There are metal flecks in the oil from pump, but no oil traces seem to be exiting the old condenser, so hopefully no metal parts, pump installation manual says if metal in oil replace whole system...
I will flush the line between pump and condenser and inspect tomorrow.
Installation manual with pump says not to add oil to direct to pump, only else where.
The pump comes with oil, manual says 1.4 fl (41ml) oz for condenser replacement.
Manual says total system capacity 4.5 fl oz (133ml) , maybe I should check how much is in the pump ?

What do you guys use to flush the system?
That oil has heaps of dye in it, there is a bolt in the centre of the compressor, add oil in there, basically the sump, as for the rest of the oil..pour into the inlet off each item if you want.Quote:

If it's filthy, brake clean first then AC flush from the wholesalers, if it's not too bad. Just the flush straight up.Quote:

Im assuming the green dye means its been refilled since new, possibly it already had a slow leak before i bought it, or its just normal leakage in 10 year car. Its probably been low on oil considering small amount I got out so may have lead to failure. I wonder if AC guy would add oil during regass or not...
So Im thinking if I do (I may not) attempt a diy flush past the tx (still installed) with new pump and condenser not in the loop, I would not be abel to connect the pump until I get it to the AC guy to put a vac on it to evap the solvent i use, ive read about turps/acetone/metho with mixed opinions. So then hook the pump up once at AC place and had vac pulled, as dont want any solvents getting into the pump/pump oil. Ill ask the AC guy what he thinks and if he can do one.
As for oil do I pour out what oil is in the pump to measure it, and then add it back in, plus the difference to make up 4.5 fl oz (133ml), I will like get it added in the H or L valve, this way I can put it all together, and drive into town, get extra oil and gas added.
Here is the manual that came with the pump, interesting to note section on "Run in procedure", and instruction to "Never add oil directly into the compressor"

Just got off phone to local AC tech, he said impossible to flush past TX valve so I dont think ill bother with flushing.
He also didnt seem to think I needed to add any more oil to the pump. (I think Ill still measure it just to know, in case I decide post install (today) I decide to add more, (which his machine can do during gassing).
He also didnt think there was any problem driving it without the gas, and considering shane said he drove his for 5 months with no gas, its likely fine. I was thinking that seems the pump has oil in it, it should be fine and any that gets flicked out would just run back in as lowest point in system. This way I can just put it all back together and drive in ready to be gassed tomorrow.
