If you wait until you can see coolant on the dipstick, you have waited far too long.  |
I was addressing Rurik more than you. If he suddenly lost more than 1/2 gallon of coolant into the oil, I think the oil would not be jet black. Also, his description of the event did not make me think he had overheated to the extent of blowing a headgasket. I simply recommended that he do more analysis before jerking off the head. I did not recommend that he drive the car without further investigation.
Of course, he may have a blown gasket, but why tear into an engine without more evidence?
