A/C System Leaks 700

My '89 740GL needs regassing every couple of years, It has a retrofit kit
to convert it to R134a gas. The compressor is a sanden which does its job faultlessly. but there is some doubt about the sealing ability of the system.I've had it checked by my mechanic and he's put the test guages on it and it has come up trumps.

Another friend of mine who owns an '86 model has had no problems with hers and it has held its gas for over ten years now and goes much colder than mine when gassed but hers is an R12 system so I dont know whats going on with that!

I've been told that the new systems are much more eficient and much more colder than than the previous systems, Is this true or or is this "Clap Trap" as I cant test it with my system.

Maybe that the R134a system is not as good as the previous R12 systems on sealing the refridgeration side of things in the A/C system.

If anbody knows the answers to any of these questions, drop us a line on the brickboard site.
