I think I figured out why my AC compressor would cut out, mostly under accelleration. After researching posts on this site, I went to check the compressor clutch air gap. It was within the spec, 0.50mm, but when I pulled the feeler gauage out it was coated with a thick oil. I am almost sure it is refrigerant oil, it has a bad smell to it similar to following a hog truck.
The power steering leaks very slightly (a pint lasted four years) and besides, the PS pump is back a few inches from the compressor, it doesn't seem likely it could get in there. And PS fluid smells a whole lot different.

The compressor is two years old, a reman. I suppose to change the shaft seal would require a discharge and compressor removal.

One question I have is, could an overcharge have caused this, and if the overcharge was corrected, is it possible the seal may stop leaking?

I cleaned the surfaces by repeatedly spraying brake cleaner in there while intermittenly engaging the clutch. It came pretty clean, but I wonder how long it will remain so.

I would appreciate any feedback from those with AC experience.

Thanks, Brian
