Hi All,
My 1970 GTO w/factory A/C uses the A6 type compressor and POA valve. The compressor failed (noisily) and I'm concerned about debris and contaminants that may now be spread throughout the system.
It will be returned to service using a reman A6 compressor with a new expansion valve and drier. It'll be converted to R134. Circumstances force me to continue with the original condenser out front, so it is what it is. I have a set of gauges and know how to adjust the POA for R134 prior to reassembly, and that the A6 compressor uses 11oz of the appropriate oil. I'm also aware that all of the o-rings will have to be changed throughout and the tools and concept of system flushing are easy enough to grasp. However, my question is this:

What advice can anyone give about flushing or cleaning the original POA valve? I'm concerned about the flush reacting with the various seals and such contained inside as well as the ability to adequately dry it out and relubricate the internals. It's silly to flush the system and not do anything about the POA valve. I can't find anyone talking about this anywhere on the Internet. Thanks!
