    I know I you can buy a small can with 1 oz of pag oil with an oz or 2 of 134a and some of fancy 134a or stop leak. I have a can at home and just cant remember what the 3rd part is. Wal mart has them.

IIRC the evaporator holds 1 oz oil approximately.. Pretty sure I saw that on something that @IBMobile or @Mopar1973Man posted here. I do you should add some oil after the replacement. If it has been leaking a while maybe more. Those 2 are more versed in it than I am.

Thank you. The vacuum is holding so maybe the leak is fixed.

Can you get pag 100 mixed with a/c refrigerant in a 12oz can. That would make the oil easy to put in sense the vacuum is already pulled. I should have asked this question before I put it all back together. Thanks.

I found some on amazon. Maybe napa will have it. I will check tomorrow.

So do other places but for double or triple the price. Not the biggest fan of WM but somethings I cant pass on.
