My a/c had a leak and all the r134a was gone. Had to replace the high side input valve. So that fixed the leak. Prior to finding that the leak was present, had a shop put in coolant and they put gauges on it and with coolant, had high side reading of 300 to 350, just sitting there at idle. Would go down to 250 or so at 1500 RPMs. After fixing the leak, and evacuating the system, a well meaning friend figured we ought to put oil back in the compressor so we added 4.0 oz. I think that was likely a mistake because could only get 12 oz coolant in before the high side pressure got up into the 350 range. Also replace the orifice tube at the same time. It was covered in what appeared to be baked on black crud. At this point, going down the road on an 85 degree day, I get 45degree air out the vents, but at idle at a stop light, temp spikes up and the system goes into "max" which I have read is a symptom of excess high side pressure. So, my analysis is that I got too much oil in the compressor. I have not been able to find a way to remove any of the oil. So, I guess my next step is to replace the compressor. What do you think?
I know that if I replace the compressor, I have to replace the dryer/accumulator/dehydrator aluminum can on the firewall. Would appreciate any helpful how-tos on removing that litttle thing cause I don't want to break the aluminum lines.
