Last Wednesday nite my kids and = I drove the 5 hours to Killington, VT to catch the tail of spring skiing (turns = out it ain't the tail at all, they are planning to be open well into = June!). At about 11:30 at nite on Rt. 91 North in the woods of Vermont with not = another car in sight, the coolant lite starts flashing. Took the first = exit, pulled under a light and opened the engine hatch. Main coolant = tank nearly empty. Overflow tank, doing just that, in fact squirting = out the breather hole on the top. Allowed it to cool, topped the main tank = with some water and continued on. OK for the next 4 days around = Vermont. On the way home today, blink, blink again. Same drill. Got home and = investigated. Every bleeder burped air or something. Many = hose connections were weeping as if under way too much pressure. The = engine is a rebuild with about 20k on it, but I'm thinking that I must be = looking at combustion pressure getting into the cooling system; ie: failing head = gaskets. Tell me I'm wrong; pleeeeese!
