Low side service port leaking, bubbles of oil.

When you guys fill with the small cans how do you know the pressure in the can is making it into the system besides the gauge readings of course. What I mean is as the system gets up close to the pressure it needs to be is it hard for the pressure in the cans to push it in? Do you even get all the Freon out of the can? Does anybody follow what I am saying?

I saw on youtube, you put it on a small postal digital scale and watch the weight go down. I guess you cant get 100% out, I threw an empty in the fire and when the self sealing plastic melted a split second puff came out.

So the can stays upright the whole time? I see different info about this. I have read somewhere you tilt the can side ways then up right- back and forth?

And I guess you have to hold the hose a certain way to keep it from throwing the scale off too?

I will hold the can with my hands wrapped around it, heat makes pressure helps the freon flow. We used to use a pail of hot water when it was cool out, drop the can in the water while it's hooked to the gauges it will flow faster.

Just thinking about all this, tot he original question... should the oil be bubbling out of the service port though? Should it even be right there? Does it circulate throughout the system?

 

[Eman85]

Oil circulates through the system. If you flush a system and replace the accumulator you put oil in the accumulator and condenser before you recharge. When the oil was bubbling out was the system charged? Did you just remove a hose from it?
