How does your orifice tube look? I believe you replaced it back in 2013, it may have been gunked up again very quickly
When the old compressor went south it likely filled the whole system with little bits of metal and grey gunk
So the new parts you install were starting to fail the moment they were put into service.
The only way to get the "black death" out of the system is to replace all the wear parts, and flush/clean the system before pulling vacuum and putting the new parts in service.
Just because your system will hold 28 newtons or whatever of vacuum does not mean it will hold 160+ psi when in operation.
We pull the vacuum as a leak test (kinda) but really it is to remove all air (potential H20) from the system
Huge PITA I am going through the same thing with 3 of our trucks....3 of them!!!! This is what happens when you drive old stuff.
I do not have a flush machine they are big $$$$ so I will be paying a local shop to clean/flush my ac systems before I pull vacuum and charge......that is the plan anyways
The Four seasons stuff has been good for the $$$$
It's not the new parts fault that the "black death" already existed in the system
