I recently pulled my 180k mile evaporator and heater core. They weren’t in terrible condition. You’ll mostly want to clean, take care of any steering column issues if you have them, take care of any...

AC Overhaul
I tried one recharge at my buddy’s place; the delta was pretty small. Same issue. I recognize the low side pressure read was kind of low based on what I found on other threads around here; might have...

Yeah maybe the oil is covering up a problem. But, again, this is my first go at troubleshooting this kind of thing.

It's Dead, Jim ('01 3.0i)
I do have an air compressor but no leak down kit. It’s easy enough to retry the compression test with a squirt of oil in 2 and 4 that I’ll do that first.
Edit: I did try multiple runs on cylinders...
