Question regarding expansion block

Desp on Mon April 20, 2009 11:00 PM User is offline

Year: 1996
Make: Saturn
Model: SL1
Engine Size: 1.9
Refrigerant Type: a134
Ambient Temp: 70
Pressure Low: na
Pressure High: na
Country of Origin: United States

Kind of a follow up of my previous thread (http://www.autoacforum.com/messageview.cfm?catid=2&threadid=20362).

I just recently took the entire system apart, before removing everything I tried to blow compressed air through the high side, and the low side, it didn't pass air going either direction. (Around 70 PSI). I'm not sure if the expansion block is supposed to stay open at all, or if it requires higher pressure to open up. After taking apart the entire system air will blow through everything. When I blew out the condenser I got greenish oil. Air would pass through the Dryer fine. But when I blew out the evaporator I got a dark yellow frothy substance. I will be running a A/C flushing fluid through the system. My two questions are,

Do you think the expansion block is bad (and or is there any way for me to tell?), and how much (and type) oil do I need for the entire system? (It has a new compressor and a new dryer).

Thanks!

Edit: There is a little rubber cap on the top of the expansion block, if I take it off there is a snap ring which is holding the top in place. Is there any reason I can't take off the snap ring and disassemble the expansion block, cleaning out any debris, and put it back together? I'm trying to do this as cost efficiently as possible since I paid hardly anything for the car, and it has a lot of miles, but I do not want to put the entire system back together and waste another charge if it doesn't work.

Change the expansion valve, why go thru all that work just to have the system fail. When changing compressors, you should always change the drier and valve, some compressor makers won't warrant their compressors if you don't.. Hope this helps..

That's me! I actually returned the Drier I bought at a local auto parts store, so I could buy the one from you guys, plus the expansion valve.

Now as far as the oil, does 8 oz. of Pag100 sound right?
