From what little I have gleaned so far, the gas leak down is the main and obvious problem. But there’s a lot more seals than just in the compressor.

I have a brand new pump for the older cars. As it was new only a few years ago (2016) I would imagine that it should be R134 compliant at least.

Now, I heard from an aircon service a short while back that even R134 is superseded. Or to be.
