Every standard piston/crankshaft vehicle made nowadays has an engine block and a cylinder head which bolts on top. Between these components is the eminent head gasket. The head gasket is probably the most crucial seal in the automotive engine. Since the birth of the internal combustion engine, head gasket designers have specified many materials to meet this important sealing challenge.
The function of the head gasket is to seal both the compression of the cylinders and the coolant flowing between the block and the head. Most car owners do not consider a head gasket replacement or most people think that a blown head gasket will never cause a problem. But they are wrong. However, it still depends on where the head gasket is blown. If it were blown into an oil return passage, then replacing it would probably fix your hitch.
So how can you determine if you have a blown GMC head gasket? It is not common to find a bad GMC head gasket on newer GMC models and other modern vehicles, but it does happen. If your auto has overheated and has not run well lately, your GMC head gasket could be the reason. Though current gasket technology drastically reduces gasket wear, eventually, your GMC head gaskets will wear down.
On engines with aluminum heads, warpage from overheating is a common problem. The heads warp as aluminum has a coefficient of thermal expansion which is two to three times greater than cast iron. When an aluminum head gets hot, it tends to swell and bow up in the middle, causing a loss of clamping force across the center portion of the head gasket. The gasket may then begin to pour out combustion gases between the center cylinders, or allow coolant to enter the cylinders. This upward distortion in the head may cause an overhead cam to bind in its bores as well, and sometimes break.
Other symptoms of a blown GMC head gasket include a constantly increasing consumption of coolant, a milky accumulation found below the engine oil cap after extensive engine runs at operating temperature, a very apparent thickening or sludging of the crankcase oil, gas bubbles going out through the radiator cap, or enigmatic oil consumption. If you’re encountering such problems, you may have no option but to replace your GMC head gasket. Luckily, finding for replacement head gaskets these days is just a click away. But if you want to get reliable replacement auto parts, Parts Train is only the best place to go.
