this is what happened in the past. I believe that with a synthetic oil and better ring seal technology (it exists it just has to be used) that oil and water can be kept seperate for the most part and that when they do meet that they do not produce nasty compounds. I don't know of anyone looking into it right now, but I plan to try some test systems out on a turbo diesel. (When I turn the key what will happen?)

also I am talking about water injection as an entire cooling system not a intercooler or whatever.

also a good note that with water injection cooling with a no-loss system (as in you don't need to keep filling up on water) then efficiency can be raised very high as it is theretically possible to have exaust temperatures that are lower than intake after turbocharging temperatures. (a theretical but believeable example would be exaust temp of 20deg C and a intake after turbocharging temp of 300deg ((no intercooler)))
