Re: '99 Tacoma Overheating
A combustion leak test as I mentioned will tell you if there is combustion leak in the cooling system. It will not tell you which component is causing the problem. You can also have a cooling system pressure test performed to see if the cooling system holds pressure. To find the exact problem the engine will have to be opened and inspected and the parts inspected/tested.
FWIW: Bad valve seals leak oil, oil smoke is usually blue, fuel smoke is usually black and coolant/water smoke is usually white.
