The Vanagon is not the only vehicle that has engine issues. Just check out the Yellow Pages in any major town or city.

I appreciate the help with diagnosis. Can't wait to check for the air bubbles in the coolant, or the coolant/oil mix. This vanagon lifestyle is not for the faint of heart.

Check for oil in coolant and coolant in your oil, coolant in your oil could trash the bottom end. What started as a possible head or head gasket issue could turn worse. On another make I have seen the water pump impeller corrosion to a point that the blades were falling off. A thermostat is a quick and easy swap as long as the bolts come out.
