The engine head is one of the most critical components of your vehicle’s engine. Positioned above the engine block, it plays a vital role in maintaining pressure, ensuring proper combustion, and preventing oil or coolant leaks into the cylinders.
However, due to constant exposure to high temperatures, the engine head is vulnerable to damage over time—which can lead to severe engine malfunctions or even complete engine failure.
🚨 Common Signs of a Damaged Engine Head:
-
Unusually high engine temperature
-
Excessive consumption of engine oil
-
Oil mixing with coolant (milky fluid appearance)
-
A burnt rubber smell inside the cabin
-
Gray or white smoke coming from the exhaust
🔧 Why the Engine Head Matters:
The engine head seals the engine’s cylinders tightly to maintain optimal compression and performance. It also acts as a barrier to prevent oil and coolant from entering the combustion chambers. When damaged—often due to overheating—it can no longer perform these critical tasks effectively.
🛠️ How to Check for Engine Head Damage (Simple Test):
Warning: This test should only be done with a cold engine to avoid burns or injury.
-
Start the car and let it run for about 2 minutes so that the engine remains relatively cold.
-
Firmly press your hand over the radiator opening (use a cloth or gloves for safety).
-
Ask another person to press the accelerator pedal 6 times while the engine is still cold.
-
Let the engine idle normally for a few moments—do not press the accelerator again.
-
Remove your hand from the radiator opening.
What to look for:
-
If water comes out of the radiator hole, this is a strong sign that the engine head may be damaged.
-
If no water comes out, it’s a good indication that the engine head is still in proper condition.
