More reliable heat and a cooler engine for longer life seems like something that needs to be tested. It just needs to be plumbed where cool water needs to be the first entry into that heat exchanger, then enters in the water box, then the water pump, then the exhaust heat exchanger.
With that setup, the theory suggests that cool water interacting with the engine oil should cool the oil down faster than room temperature air outside, giving longer life to the engine.
Is any of the big wig manufacturers lurking on here to prove this theory wrong? Or would this make the engine last longer and help the smaller machines perform better which would hurt your sales goals?
