RE: A/C Compressor...bench test

You can get locally (CA,LA area) a rebuilt Nipondenzo for $180-190 (with
core), NO Manifold included, most of the time when the manifold leaks it is
the O-rings (assuming you have a one piece manifold), if you have a two
piece manifold, it is a different story........
Dave, excellent tip on the fresh air seal...........
