While there are certainly other opportunities for an A/C system to leak, the most common problem is the o-ring seals thruout the system. The lines, fittings, etc., on the 928 are sealed by an o-ring at every joint, rather than the more common metal-to-metal seal. The o-rings get old and hard from high temps and oil soaking. It is time-consuming, but usually worthwhile, to just replace every o-ring in the system, clean the expansion valve screen (or change the expansion valve), change the receiver-dryer, vacuum and charge it with R-12.

Be sure to use the latest material green o-rings.
