Seriously so did I have in mind that if the oil separate and clogging it or get or get cold and
tough. You never know now this days what you get and if you have a cheap mix you filling with or buy no name oil on ebay and topping it with you can make a mess in the end.
And the grammar in my first post wasn't pretty, I can better.

I gotta take mine to the Toyota dealer to get it repaired knowing the GM dealer will use the mechanical a/c machine on my electric a/c (OILS used are different using the incorrect oil type will damage it)

bet he did not vacuum out the old Freon and vacuum the lines out before putting the new Freon and oil at lest there is no mention of that

When he completely opened the system the need for a vacuum recovery is no longer there. He may have just let it go to the atmosphere. The old oil is in there except for what was in the bottom of compressor and accumulator and the condenser. Those were replaced and now system will need new CORRECT oil. I am still leaning toward the wrong compressor because he still has not answered that question put to him. Yes, he still has to create a vacuum to recharge and he did not say he did that either.

hi all, im charlie, new here and seeking some a/c help.
i ham having a mystery issue regarding the installation of a new compressor.
the original one finally failed, ive so far installed a new compressor, condenser accumulator and lines. once the recharge is started, with only one pound of 134, after a few cycles and about45 seconds the freon lets loose through the blowoff valve in the back of the compressor and the clutch seizes. im on my 3rd compressor. no blockages have been found as of yet. im kinda flustered, can anyone provide any clues?
thank you.

I have. 93 Silverado that I had an issue with as well but found what the issue was. On he high side of the compressor, if you compare it, you might find that it's slightly lower than the low(suction) side. After three compressors, I took the compressor in and showed him and compared it to the original to show the parts guy. The resolution was to get another one, buti made sure that the seal/O-ring was thick enough to compensate for the high side being lower. It worked and yes, I did switchf R12 to R134. Yes, I did vacuum the lines as well.
