About three months ago I replaced the compressor, condenser, orifice tube, and accumulator. Took the lines off and flushed them with AC flush. There were no mufflers in the lines. Also flushed the evaporator. It's back today. The compressor is getting noisy but still cooling well. The o- tube has metal flakes.
This is police car and when it came to me the first time it had Black Death. A trusted local parts guy told me the only way to fix it is replace everything including the evaporator. Not sure how to proceed from here.

So how did you flush and what chemical did you use?
It can be fixed.
I used a flush gun that I bought from AC kits a long time ago.
The flush I used was in a quart bottle. Said AC flush.
Don't know what chemical it is.
Would like to add that the debris at the
orifice tube looks much different than the
First time I worked on it. First time it was packed with black stuff. This
Time it is shiny metal. The black stuff the first time didn't appear to be metallic
Did you watch the video in the "flush" link of my previous post. The 1 qt flush gun and 1 qt of flush is not enough energy or solvent to get the job done on that evap. I am not trying to beat you up; I want you and others to just think about it. Just poofing something at it, is not flushing. How did you validate your flush work? You don't know what kind of flush you used; besides possible not getting all the junk out, did you get it all the flush out, or better yet can you get it all out? Snake oil is sold in quarts. The black stuff before was burnt/overheated oil from a slow death, you new compressor is grinding up metal fines, sometimes they just won't die right away, but they will get real hot; maybe its a bad unit, maybe a diluted lube thing, maybe some remaining debris. The parts guy forgot to start his "only way to fix" it statement with, "If you are not going to flush it right, or have the tooling to flush it right", then replace everything. But hey, he sells parts, and I make flushing tools; who ya gonna believe, and how many times do you want to do this.
