what happens when you have too much a/c pressure on the low side?

what happens when you have too much oil?

Everything is fine when i start the car and rev it. About the 3rd or 4th time i rev it starts making noise. I have about 70 psi on the low side. Trying to add more a/c oil and the stupid a/c gun thing won't let me add any. I've been fixing leaks on the a/c system. It sounds like water going down a sink, kind of gurgle-ly.

 

Have you tried changing the orifice tube?

 

no, i haven't. Would it be bad even if i have cold air coming out of the vents?

The longer that i let the car not run and then start it, the longer it takes for this to happen. Pressure on the low side slowly increases and the compressor starts making noise when the pressure gets too high. I'm going to let a little bit of freon out and try it again.

 

It was too much pressure and too much freon. I let some out and it works...for now.

 

Glad you fixed it. Gotta have that A/c
