What causes the head gasket on a Toyota Land Cruiser to fail?

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.

Can a head gasket failure cause an oil leak?

While not as immediately dangerous as other types of head gasket failure it will still require repair as it will only get worse over time.

What happens if you blow your head gasket?

Eventually, this gasket deteriorates. At some point, it “blows,” meaning that pressure in your engine is reduced. When this happens, your engine will generally begin to leak oil where the seal is no longer holding. As a result, your engine can no longer maintain the proper amount of compression and ceases to function.

What are the symptoms of a blown head gasket?

Most of the symptoms of a blown head gasket are obvious, since the way that the engine runs is usually affected. Here are some of the most common signs of a blown head gasket: Rough/Choppy Idle- When a head gasket blows, it will lower the effective compression ratio of one or more cylinders. This is always most noticeable at idle speed.
