I would think this lily mess is a sign of an oil leak from a 134a retrofit.
I’m not going to touch hvac for a while on my new 1991 350SD. But I do want to think about what I may face.
To me it looks like there is oil loss around the high pressure fitting, as things are cleaner elsewhere. My gut would be bad schrader.
I intend to leak check in my standard way with HC refrigerant. But I want to address low hanging fruit first.
Thoughts?
