Not a bad idea in terms of removing O2 from the system. I was surprised to read Carsten's experiences with the oil expanding from the heat of motor operation given the excellent heat sink properties of water.

I wonder if the use of nitrogen in a stand alone compensation system would be worth a try. And a slow, end to end system flush after diving. With no oxygen left in the system, rust would be held at bay, and the flush might warn you of excess moisture. Beyond that, it's hard to deny his experience. His system works. The oil comp does, too, so it gets back down to a choice. |
