My A/C compressor had the all too common front oil seal failure, squirting a fine mist of messy refrigerant oil all over the engine compartment last summer. I purchased a reman A6 unit, installed it, drew a vacuum for a few hours, let it sit for a few hours to ensure no leaks, then filled the system with 60 ounces of good ole fashioned R12. All went well!
