The first symptoms of a head gasket that is failing are usually a slow loss of coolant with no visible leaks, engine overheating and/or a Check Engine light with cylinder misfire codes.
The Onboard Diagnostic II system should detect any misfires that occur due to a loss of compression or spark plugs fouled by coolant seeping into a combustion chamber. So if a vehicle has a Check Engine light on and a cylinder misfire code, the spark plug in that cylinder should be removed and inspected for coolant fouling. A compression or leak down test should also be done to see if the cylinder is losing compression. Internal coolant leaks caused by a leaky head gasket can usually be diagnosed by pressure testing the cooling system.
Regardless of the cause, a head gasket failure is bad news for the vehicle owner.
Depending on the application and how much labor it requires, the repair bill might run $1,500 or more for parts and labor. The parts required to replace a head gasket include not only the head gasket itself, but also all the other gaskets that have to be replaced to disassemble the top of the engine.
