Decatur is a small city located in northeastern Georgia, just 5 miles northeast of Atlanta. The city was founded in 1823 at the intersection of two Native American trails and named after US naval hero Stephen Decatur.
The main function of a head gasket is to hold engine compression while keeping oil and coolant circulation separate. Undetected blown head gaskets cause coolant and oil mixing, which could lead to severe engine damage, such as engine block cracking.
Engine overheating is the number one cause of head gasket failures, according to Mobil Oil. The cylinder head and engine block expands beyond acceptable limits while overheating, which leads to head gasket pinching. Improperly torqued head bolts and abnormal air fuel mixture combustion are common reasons as well.
