I have a rear line leak in my minivan. A rear ac block off kit is a simple remedy to this otherwise expensive repair. My problem is that right now my ac lines are 1/2 filled with hydrocarbons. In canada we can't buy r134 so most popular ac refill from can is r12a.
I can't get this evacuated easily. I visited a mechanic & they won't do it with their machine. If i cut those lines will all refrigerant escape? Likely yes but will there still be traces of r12 that vacuum machines can read after the block off is installed?
