The cylinder head is a crucial part of your engine, sealing the combustion chambers and allowing coolant and oil to flow properly. A cracked cylinder head can lead to serious engine issues, including overheating, power loss, and costly repairs. Recognizing the signs of a cracked cylinder head early can help prevent further damage.
Common Symptoms of a Cracked Cylinder Head:
- Overheating Engine
- A cracked head can cause coolant leaks, leading to engine overheating and potential long-term damage.
- White Smoke from Exhaust
- Coolant leaking into the combustion chamber burns as white smoke, indicating a possible crack.
- Loss of Coolant
- If you're frequently topping off coolant with no visible leaks, a crack in the cylinder head may be allowing it to escape internally.
- Oil Contamination
- A cracked head can allow coolant to mix with engine oil, creating a milky or foamy substance on the oil cap or dipstick.
- Poor Engine Performance
- Misfires, rough idling, or loss of power can result from compression loss due to a crack.
- Check Engine Light
- A cracked cylinder head can trigger sensor readings that illuminate the check engine light.
- External Leaks
- Visible oil or coolant leaks from the cylinder head area may indicate a crack.
A cracked cylinder head is a serious issue that can lead to severe engine damage if left unaddressed. If you notice any of these symptoms, it’s crucial to have your engine inspected by a professional. Catching the problem early can save you from costly repairs and potential engine failure.
