I'll bet you that the valve port to the left of the TX valve is one of your leak sources. Being coated with oil and grease seems

always tells of freon escaping. Try to see if that valve cap has a  O ring in it?  If not, put one!

Your first pic. top dead center, Thats the expantion Valve! [thormo expantion valve or TX for short] Look for stamped #'s or print.

On your 2nd pic I see the WHITE reciever tank that is used for R-12, [still dosen't confirm] and the main story I see

is all your fittings are well established in corrosion. Looks to me like the system is orriginal R-12!

Let me know if you see anything on the TX.


Nick... Hi
Can't find anything on that TX
