I have purchased new ones, they do not last any longer than reman, just cost more. New ones have GM sealing washers, reman has o-rings.

The MB R4 is a bad design, On my GMC R4 the ports or up and oil feed to bearing flows down unto shaft. With MB ports are down and oil has to flow up which causes bearing and shaft oil issues.

Before, I have always flushed system before. Replaced dryer exp, ect...My compressor did not lock up,it is working. So I am going to just drop in another, vac and recharge.

I am going to drop in an Oreilly-Murray (four seasons), from texas just like the autozone one (compressor works).

One day I am going to get hoses fabricated and mounts to do a denso.
