Well.. Before I go and dump propane into my system.. I decided to test it out with pure 134a.. has no oil in it..
Well.. so far.. not good.. I have no cooling on the evaporator.. the high side pressure is low.. only around 100 to 120PSI.. the low side is in a vacuum.. between 10 and 20".. the compressor makes an odd humming sound too..
I guess it won't do 134a.. I don't know.. either that or most of all the oil came leaking out when I cut the system.. which is a good possibility.. when I cut the lines to get the compressor out a SHITLOAD of oil came out.. and then a ton of it misted out as well.. so really good chance that there isn't much oil in the system.. which would explain the high compressor temps.. I am going to stick in propane then.. see if I actually get cooling or not..
I took care of some blocks and leaks in the system.. everything is good now.. so I know I don't have a cap tube block or something.. just don't know why the 134a won't cool..
