Ahh, missed that. I take back everything I said (well most everything). I agree about every Oring, and add that the compressor manifold seal (not exactly an Oring, but made of the same material) should be replaced as well. Did the system originally come with 134a? If it had R12 from the factory (I assume this), then it probably had mineral oil. I don't know for sure, but MB might have gone with Ester in the Denso compressors then, and that would be good. If it had mineral oil, and was retrofitted to 134a, that would be a problem.
