I have been occasionally and faintly smelling the delicious odor of scalding coolant for a few days now. Then today went to pick up my sister at the airport (150 Miles Roundtrip) Before leaving, I checked the fluids. Oil was clean - and only oily. Coolant reservoir was overfull and also oily. Radiator, on the other hand, was not full. Needing to leave right away, I topped it off with water. Hard to say how much, since it was from a garden hose, but I would guess about 2 cups of H20.
Picked her up, stopped for gas at about 100 miles. Checked the coolant reservoir - looked the same, but I dipped a bunch of shop towels in to collect the oil floating on the surface of the reservoir (about 1/8 inch). Now the coolant looked scuzzy, but green on the surface. Continued driving. About a mile from destination, temperature needle stood straight up. I coasted into my parent's driveway in a cloud of steam.
Looked in the reservoir - now it is entirely full to the point of overflowing - haven't opened the radiator cap yet, but it was cool to the touch. Water return hose (top passenger side of radiator) was hot. Coolant still appears to be clean(ish) - no layer of oil - just flecks that the shop towels didn't pick up.
I have a mechanic at home I trust - back home in Seattle. We are 250 miles away, and are supposed to get on a plane from Seattle the day after Christmas - Can I safely drive it 250 miles without major mechanical work being performed? I can probably get a rad flush on the 24th, but probably not anything more extensive than that. Should I send wife and daughter home on the train and wait for a Head gasket change?
Any suggestions?
Thanks,
Adam
