2" - 2.25 Exhaust Question /6

Pull the breather out and swipe your finger around in the valve cover, or flip the breather over, and look for white slime or water droplets. This could be normal where you live, and may be caused by short trips and or insufficient running time to evaporate the moisture that your PCV is constantly pulling in from the atmosphere. A too cold thermostat could also do it, as can an open-type non-heated air filter housing. That moisture may be piling up in your crankcase as water, in the bottom of the pan. You need to check it. Pull the dipstick; if it too has the slime on it, then change your oil, or at the very least drain some out, looking for water. You have to do this after the engine has cooled off to allow the water to come back out of solution and settle in the lowest part of the pan. This used to be a common problem in older cars without heated air intakes and non Closed Crankcase Ventilation Systems. You have to cure this, if I'm right, because the moisture will combine with blow-by elements to form acids which don't do your engine any good.
Short trips at this time of year are killer acid producers
