ok, back on this project now. Oleg and Bazar, I took your advise on trying to trace for leaks with close inspection and soap water before trying the vacuum test. Can't see any signs of leaks or bubbles, but when I peered down under the exp valve with a flashlight I could see some fluid trapped. It's right under the exp valve, behind the firewall. It feels just like motor oil and is yellow in color. I'm guessing this is PAG oil since I can't think of how motor oil would get in there. Yes?
So, given the low side pressure is too low, and the evidence of presumably PAG oil, I'm leaning towards replacing the EXP valve. Do I also need to replace the dryer while I'm at this?
