My car has over 500,000 miles on it. There is coolant in the oil; there are whitish globs of gunk in the oil and on the filler cap and dipstick. There is also engine grime and small amounts of waxy off-gray slime in the coolant overflow/filler tank (specifically, in a ring on the inside of the filling hole). I am willing to do a good amount of work in order to fix these problems. I am pretty sure that there is a problem with the head gasket. What should I do?
