What is a Head Gasket and Why Does It Fail?

The head gasket is a crucial component in your engine, sitting between the engine block and cylinder head. It seals the combustion chamber and prevents engine oil and coolant contamination. When a head gasket fails, it can cause overheating, loss of engine power, and contamination of oil and coolant, leading to severe damage. Prius head gasket problems are particularly concerning due to the unique hybrid system design, especially in the third-generation Prius head gasket.

Common causes for Prius head gasket failure include:

  • Overheating Engine: A frequent issue in hybrid vehicles due to complex cooling systems, often involving the water pump and thermostat.
  • Wear and Tear: Over time, heat and pressure wear down the gasket material, especially in models like the third-generation Prius head gasket.
  • Improper Maintenance: Lack of regular coolant changes or engine tune-ups can accelerate wear, potentially leading to a blown head gasket in Prius models, including the 2015 Prius head gasket.

Modes of Failure

The head gasket seals the combustion chamber, coolant passages, and the oil galley. Usually, a head gasket will develop one of the following types of leaks:

  • Coolant passage to combustion chamber
  • Coolant passage to oil galley
  • Combustion chamber to combustion chamber
  • External coolant leak
  • External oil leak

The Prius head gasket usually develops a leak between a combustion chamber and a coolant passage. Coolant leaks into the combustion chamber and is then pumped out the exhaust as steam. When the engine isn’t running, coolant from the pressurized water jacket can leak into the combustion chamber. This is a big problem on the Prius since the engine stops running frequently, potentially leading to coolant depletion and an overheating engine.

Symptoms of a Leaking Head Gasket

Often a misfire is one of the first early warning signs you’ll notice on a Prius with a leaking head gasket. A misfire on a Prius is usually fairly dramatic. The engine will knock, shake, and rattle when it starts up. The misfire is caused by coolant leaking into the combustion chamber and fouling the spark plug. The engine will continue to misfire until the plug dries off.

Prius Specific Symptoms

  • The car will shake and rattle when the engine starts.
  • The check engine light or master warning indicator will flash while it’s running rough.
  • Then it will eventually smooth out as the engine gradually smoothes.
  • However, the next time the engine stops for a while, the problem may return.

Possible Additional Head Gasket Damage

The other problem with coolant in the combustion chamber is this: coolant can’t be compressed. If there’s enough coolant in the combustion chamber, the powerful electric motor can actually bend the connecting rod while trying to push the piston into a space already occupied with a non-compressible liquid. This isn’t common on non-hybrid vehicles because the starter motor is so much less powerful. On a conventional car, the engine usually just stops cranking.

Luckily, bent connecting rods are relatively rare, but we’re always sure to check. There’s no point in putting a new head gasket on a badly damaged engine! Checking for bent rods is easy. We check the piston heights relative to the troughed deck surfaces. If one piston is sitting lower than the others, there’s a bent rod. If not, we can reassemble with confidence.
