I’ve been working on upgrading the 85sd ac system. I’ve replaced the evaporator and expansion valve, dryer, new compressor(R4) a Klima condenser kit.
And of course performed a good flush on the hoses.
Pressure test with Nitrogen and a hard vacuum.

So my question is on putting in the oil, I believe it’s 8oz correct? Also I will be using a jug of 134a.
Do I charge with vapor(jug upright) or liquid (jug upside down)?
I thank you in advance,
