Well, according to what I am finding, no, it won't. (learn something new every day.) It will only get the oil that is close to the port. The rest will pretty much stay where it's at.

 

Ok so cool I wont need to add any oil.

 

Or I guess I am going to have to flush the Evaporator core?

 

Nope, just vacuum the system down, leave it for 20 minutes or so, to make sure it holds the vacuum, then recharge are necessary.

 

This is the low side port. Do i pour pag oil into the side of the receiver/dryer where my left hand is or the other the other side of the receiver dryer?

 

When you replace parts especially the receiver/dryer you need to add oil. The oil mixes with the freon and gets circulated through out the system. Most of the oil will collect in the receiver/dryer so when you replace it you need to add oil. I added the oil in the pressure switch hole before i put the switch in and installed it in the truck. This will allow it go to the bottom and wont get stuck in the line. Hook all the lines back up evacuate the system charge it and you should be fine.

 

What did you use to get the oil through the pressure switch hole? I don't think I have a tool that can pass the oil through that switch.

 

Remove the switch, I don't recall if there is a valve core in there or not, if there is, any bicycle shop will have a tool to remove them.

 

There is a valve core or a stem but I'm not sure if its serviceable or not. I'll have to look when I get home. But you're saying use the same tool I use to remove a valve stem from a tire?

 

Yep. They are pretty much a universal design. *Generally* the valve is serviceable separately.
