W140 1992 400SE.

The charge line running from the Evaporator to Compressor cracked open near the Compressor, so after discovering a new line is well into $400, I removed it and had the rubber replaced on my current line for a few dollars.

When I removed the line from the compressor about 3 weeks ago, a good amount of oil leaked out. Guessing 2-3oz.

Now with the line repared, new receiver/drier, new o-rings for each hose connection (8 total), blue nylog for the treads, a borowed 6CFM Yellow Jacket Vacuum Pump and Guages, Castrol PAG Oil - ISO 46, and a couple cans of Supercool Aerosol Flush I'm ready to put it all back together.

Since the system has been opened for 3 weeks (moisture entered into the remaining oil) and I don't know how much oil leaked out (while disconnecting hose and over the comming months when only a small leak was present), I am going to flush the entire system.

My questions to those who may shed some light are:

What is the correct quantity of PAG Oil for this system (R-134a with No REAR A/C), on ALLDATA is states:
1. 160 cubic cm for new oil fill in compressor
2. Condenser
Renew. 20 cubic cm of new compressor oil.
3. Evaporator
Renew. 40 cubic cm of new compressor oil.
4. Receiver
Renew. 10 cubic cm of new compressor oil.
5. Suction line from evaporator to compressor and compressed air line from compressor to condenser
Renew. 10 cubic cm of new compressor oil for each.

Total 250 cubic cm = 8.45oz.
Does this sound correct???

Secondly, is PAG Oil - ISO 46 the correct viscosity?

Third, what is the correct way to flush the Compressor (Spray in one and out the other OR rotate while flushing???)

Fourth, what is the correct way to flush the Evaporator (Top to Bottom OR Bottom to TOP???)

Finally, I must be blind, but I cannot find the A/C Label on the vehicle anywhere....to verify the refrigerant quantity, can anyone tell me where its hidden??? ALLDATA states 1300g (w/o Rear A/C for R-12)= 2.86lbs, I know to put in 80-85% of this number into my R134a system.

Thanks for all your input, feel free to add what I may have failed to ask or specify. Thanks again.
