What causes the head gasket to fail in a car?
With a failure between cylinders, compression from one cylinder leaks into another. Lowered compression results in a rough idling engine. Damage of this type may not cause overheating, coolant in the oil or any other outward sign. Head gaskets may also fail between the coolant passages and the lubrication system.
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
