When is a head gasket failure bad news?
A head gasket failure is bad news, very bad news, and will require immediate attention. A head gasket can fail in a number of different ways (coolant leak, oil leak, loss of compression), some of which we told you about recently, and all of which are bad news for the engine.
Can a faulty head gasket cause an oil leak?
A faulty head gasket can also allow engine oil to leak into the coolant passages in the cylinder head. This often shows up as an oily/milky residue in the coolant expansion tank, as the oil floats to the surface of the coolant. Again, be careful though, as this can also be caused by a leaking engine oil cooler or transmission oil cooler. 4 Smoking

What are the symptoms of head gasket failure?
When head gasket failure occurs between two or more cylinders, several symptoms are bound to result. The most common symptom in this case is a misfire, which would result from the leakage of compression between cylinders. Evidence of this could include the following: Lowered compression due to rough idling.
What causes a head gasket to leak in a car?
However, the problem can be harder to spot in cars that use glycol oil, which is less likely to take on a milky appearance when corrupted. When a problem like this occurs, the viscosity of the oil is affected, and this will ultimately compromise the engine’s lubrication.
When does a blown head gasket cause a misfire?
The failure of a head gasket between a coolant port and cylinder can cause leakage of the former into the latter. When this occurs, a misfire is likely to happen during vehicle ignition, especially if the motor is revved up, cut and then restarted.
What’s the normal temperature of a car head gasket?
In modern engines, normal temperature levels place in the range of 200 to 225 °F. Therefore, when a temperature gauge rises to the hot zone, it means that the engine is really hot. If an engine rises above 240 °F, the head gasket and cooling system could both be pushed beyond their normal limits.
Where does the coolant temperature ( ECT ) sensor go?
The readings from the engine coolant temperature (ECT) sensor; are sent back to the engine control unit (ECU). The engine coolant temperature (ECT) sensor is one of the most important; engine management sensors.

Over time, the sheer force of the pressure inside your engine begins to wear on certain components. One of the most susceptible parts in terms of eventual wear and tear is the head gasket, which seals the bottom half of the engine to the “head.”
A faulty head gasket can also allow engine oil to leak into the coolant passages in the cylinder head. This often shows up as an oily/milky residue in the coolant expansion tank, as the oil floats to the surface of the coolant.
