I read your article with enthusiasm and open minded thirst of knowledge...You make a lot of good points. I question your knowledge of wet sleeves and cavitation, wondering why you feel the need to take away from other manufacturers to sell your product. 1.Cavitation has little to do with 'proper support' of the sleeve in a wet sleeve engine...Cavitation for the most part begins and ends with using pond water for coolant, always has been and will be in the forseeable future...Pure and simple, poor maintenance...Coolant care and condition is just as important to the life of an engine as the engine oil itself...You didn't mention IH engine in your negative engine comments and I am wondering whyIJ..lack of experience or did you overlook them being one of the first along with Cummins to experience the 'phenominom' in all its grace and glory...Checking coolant and keeping the proper additives will stop cavitation in its tracks and in the bargain will allow antifreeze to be 'recycled' in the same engine that it came in from the factory...Antifreeze is just that, and never looses its ability to keep water from freezing at its level of concentration...Additives however don't last forever, can be tested at an annual service event, and works well long as the operator understands the difference between using makeup coolant already mixed distilled water, antifreeze, and additives, not topping off the radiator with pond water...Sorry to say, this one particular point you have so erronously failed to report has me wondering how much other facts you have construed in your 'tail'. Please reply, I have no axe to grind with you and sincerely want to get to the bottom of the cavitation issue of which you speak.
