wonder if its carbonised oil? had an LG where the comp failed and when changing the discharge pipe was full of similar stuff. Interesting to see inside thanks!
One of the worst things that can happen to a heat pump. The compressor can still get damaged after the valve is replaced due to the fact that the lack of refrigerant flow through any other part of the system can cause huge oil loss, especially if there is no crankcase heater. It's always good to install a good dryer, and add oil back in before vacuuming and recharging.
I was just going to ask you, how or why does a Reversing Valve get stuck. There's not much going on in there. Unless it's a really old one and a bunch of gunk for some reason got build up in there. I don't see how it's not possible to free them up with some heat and a few taps. Unless it's like the one in the video.
Sometimes its a blocked cap tube in the pilot valve. Virtually any garbage in the valve will cause a failure. I have never been able to free up a valve. When they stick, they are done. GFM

I love your videos man its helped me alot thank you for your knowledge you've shared. Keep up the good work
Wow. That valve was messed up. I wonder if it broke like that and all the gunk was from the compressor failure.
That could be. It appeared to have something in it from the compressor.
GFM
Yeah, you gotta wonder what the heck!

I will agree on everything except the additional oil. If the oil is still in the system, it will return when started.

I thought that a majority of the compressor oil would leave the system when the refrigerant is recovered out.
