  • Buick Skylark: Symptoms of a Blown Head Gasket

    The head gasket seals the areas where the engine block and the cylinder head meet. In the process, it keeps engine fluids from mixing and maintains optimum engine compression. When this gasket breaks, the engine of your Buick Skylark will be placed under a lot of stress. This can lead to catastrophic failure under the hood if the problem isn\'t diagnosed accurately and fixed properly. These symptoms will tell you if you have a blown head gasket or if the gasket is already heading towards failure:

    Fuel mixed with coolant or oil

    A blown head gasket will allow engine fluids to mix or to leak into one another, eventually causing engine damage. Oil will burn fast when it mixes with combustion in the fuel chambers. This will lead to unusually high engine oil consumption and can cause lack of proper engine lubrication and performance problems such as poor idle. When fuel is combined with oil, bluish smoke may come out from the exhaust.

    When coolant gets through the fuel cylinders, compression levels will rise sharply and the cooling fluid can easily overheat. This can cause damage or warpage to valves, pistons, and other engine components. Because of excessive coolant loss, the engine is at risk of overheating. When fuel mixes with coolant, there will be white smoke from the exhaust. There will be more steam from the exhaust or water dripping, and this can ruin the catalytic converter. Since combustion gases are corrosive, this will cause damage to some cooling system components such as the hoses, radiator, or any weak link in the system. Extreme pressure will build up if the head gasket is blown out and fails to seal between the coolant passages and the combustion chamber. This can blow off the radiator cap, break the hose, or crack the tank.

    Engine oil mixed with coolant

    Oil and coolant mix will result in fluid contamination. When oil is contaminated with coolant, its ability to lubricate engine parts is compromised as this alters the oil\'s viscosity. Oil on the dipstick, bottom of the oil pan, crankcase breather, or oil cap will appear like milk chocolate. When there\'s a trace of oil in coolant, this will develop into an oil film and will eventually have a discolored texture until this looks like a brown sludge. Similar to engine oil, this fluid\'s cooling ability will be adversely affected due to contamination.

    Other symptoms of head gasket failure

    Failure of the head gasket to seal between cylinders can lead to a misfire, along with other symptoms. Compression from one of the cylinders will pass or go into another. Lowered compression will then lead to rough idling. When exhaust gases find their way into the radiator, there will be constant bubbling. Excessive pressure in the crank case can cause the oil cap or engine oil seals to be blown. External oil leak may develop due to head gasket failure on the oil passage.
