Common Signs Of A Blown Head Gasket
- Milky brownish-yellow substance under oil filler cap
- Coolant and oil leaks
- Overheating engine
- White smoke from the exhaust
- Loss of engine power
If you notice a milky brownish-yellow substance under the oil filler cap, it could be a sign of a blown head gasket. This substance is a mixture of coolant and oil, indicating that the two are leaking into each other.
Another common sign is coolant and oil leaks, which can often be seen underneath the engine or around the cylinder head. An overheating engine is also a red flag, as the head gasket plays a crucial role in maintaining proper engine temperature.
White smoke coming from the exhaust, especially if it is accompanied by a sweet smell, is another indication of a blown head gasket. Finally, a loss of engine power can occur when the gasket fails to properly seal the combustion chambers.
If you experience any of these signs, it is important to address the issue promptly to prevent further damage to your 02 Toyota Undra 4.7 Liter engine.
Repairing A Blown Head Gasket
