Re: FWC kit for Atomic 4, a good idea?

I've always understood that RWC engines used in a salt water environment should never be converted to FWC. The salt is so embedded into the internal passages that it will never come out and then when converted to FWC and anti freeze is put into the cooling system, the salt will have a negative reaction with the antifreeze and clog the passages.

My suggestion, find a way that you can easily and frequently flush your engine.
I have a FWC diesel that I flush just about every time I use it. Of course, I'm only flushing the raw water side, but I figure it will buy me extra years before replacing my riser or heat exchanger. Takes me less than 5 minutes to flush my engine.
