I have a 1990 300ZX that I bought new back in 1989. It has 180,000 miles and is in pristine condition inside and out (OK so I’m anal about my cars…so what!). It hasn’t been my daily driver for a number of years and has developed a small freon leak (1lb in 2 years) in the compressor and discharge hose. I had it retrofitted from R12 to R134a. To repair the compressor and discharge hose leaks will cost over $1,000.
Since I put so little miles on it these days (maybe 400 or 500 miles in a year), I figured I would just go to AutoZone or Pep Boys and by a charge kit and do it myself as needed since there is no longer any R12 to recover.
- Do the recharge freon cans include PAG oil since I would assume some of the lubricant will escape with the freon?
- Has anyone tried any of the stop leak products to advise whether it really works or just makes things worse…a whole lot worse.
