Only you can make that decision. The evaporator replacement is a big job and there is an excellent YouTube on it. I believe the recording is by Dennis Oury. If you do decide to pull the intake manifold and dash to get to the evaporator, there are a few other parts to change out including your door actuators and remote oil sensor line. Others might suggest changing out some other parts when the dash is out. I have a new Delphi heater core which I plan to install when I finally decide to replace my leaky evaporator.

You wrote that your first compressor was a leaker and not an internal failure. Have you looked at the oil from your new failed compressor? Are there chunks and visible chips and bits?
Use of a suction screen at the compressor inlet is some protection for the compressor if you suspect debris in the evaporator.

I learned I probably only needed to replace the ac compressor, drier, and maybe flush the adjacent line. I finished it all up though replacing the condenser as well. I have cold ac now however I do still have a leak in the low side shrader valve. Ill replace it when I run out of freon.

Hey Corvette00799, you've obviously removed the compressor recently, I have a question: I have a leak from the compressor area,
neighbor had an electronic freon detector, pegs out in compressor region (from the top)
It works great if I fill it, but in the summer I have to put a can in about every 3 weeks. I haven't been under it yet,
do you think I'll be able to access the hose to compressor connection without removing the compressor?
I'm hoping I can pressurize system, and use soapy water to determine if hose O-rings or compressor seals
are the issue. I'd hate to change a good compressor.

The hose connection at the rear of the a/c compressor is referred to as the suction/discharge manifold. Some Forum members have experienced leaks at this connection. It uses a seal washer at each of the ports between the manifold and the rear of the compressor. A single bolt secures it to the compressor.
