We found a Bad O ring actually couple , We replaced all of them , New Orifice tube , pulled vacume for 45 minute ,the system hold vacume pretty well , We also converted the System to 134 with new fittings .Added Oil to the system and charged to 175 cold side with 134 , the compressor cycling pretty great . The AC is Finally working pretty good but i won't say it will freeze you or any thing like that . I am not sure if sticking with the Blue tube was the right thing . But i hardly drive the green machine but its nice to have AC for this coming weekend race trip .
The old orifice tube showed some dirt on it but not black gunk or any thing like that . I learned a great deal today between reading here and watching and helping out getting it done today , If any thing i wish i could done difference is to replace the dryer
