How would increasing the temperature lead to more water? If it is thought that the cooling after a good runup to operating temp causes water to condense, how come it doesn't happen in the summer when we are running the engine more frequently? Or is it thought that the more frequent run ups burn off the moisture before it has a chance to induce rusting? If that it the case, more frequent runups in the winter should accomplish the same thing - but, with the cost of fuel these days, desicant plugs and fogging would be considerably less expensive.
