Last week the foaming occured in my system when I backed off the gas after a long uphill pull (yes, North Dakota does have at least one long hill). My guess is a little air was drawn into the system through the water pump, which I packed with fresh packing just before the tour. The packing had settled and the nut on the pump needed to be tightened a notch. Conversion to sealed bearings would probably solve the problem. Anyone know a good shop to do that? I understand some machining is involved. I have a spare water pump I could ship off without having to wait for the winter down-time. As for now, switching to WixCool with their anti-foam compnent seems to have done the trick, although that’s just treating symptoms rather than the cause.
