Got everything hooked up today ...

Ran vacuum for 6 whole hours today ...

And no leaks and gauge stayed at 29 the whole time ....

Tried to install one can of oil (4 oz) ... not sure any really got in ... no sucking

Tried one can of R-12 and not sure any really got in ... no sucking

I have done other A/C systems before and the can of refrigerant drained pretty fast on other cars.

So, what could it be ? I am totally stumped and bumed. I thought I would be having AC this week.

Any ideas ?
