I think I've got a leak... I went to DEQ today and noticed coolant coming out of the overflow... the temp was also pretty hot, although not hot enough to worry about... I also noticed bubbles coming up in the overflow tank..... so air is obviously in the system... I checked the radiator hoses and it appeared nothing was leaking... drove for a block and the temp was steadily increasing so I parked it for an hour, had lunch and came back with distilled water. She drank about a quart, I then drove home... on the way home (approx. 12 miles all highway) temp stayed where it should... and I noticed no visible exhaust or smell. Upon getting home the overflow was once again boiling over... I *think* I see a little bit of oil when I open up the radiator... but I can't be sure... so what's the best way to determine if it's my head gasket? Will compression alone tell me? Should I get a Q-tip and attatch it firmly to something to see if there's water in the cylindar?
If it is the head gasket, what's a good replacement? how thick is still safe to go with?
