🚗 What Happens When You Have a Head Gasket Leak?
A leaking head gasket is one of the most serious engine problems a vehicle can have. The head gasket seals the engine block and cylinder head, keeping oil, coolant and combustion gases where they belong.
When the head gasket starts to fail, those fluids can mix or leak, leading to major engine damage if it's not repaired.
Common signs of a leaking head gasket:
🔥 Engine overheating
💧 Coolant loss with no obvious leak
🌫️ White smoke from the exhaust
🛢️ Milky oil (coolant mixing with engine oil)
💨 Bubbles in the radiator or coolant overflow bottle
🚗 Poor engine performance or rough running
Why you shouldn't ignore it
Driving with a leaking head gasket can quickly turn a repair into a complete engine replacement. Overheating can warp the cylinder head, damage internal engine components and lead to very expensive repairs.
If you've noticed your temperature gauge running hotter than normal, your coolant level keeps dropping, or your vehicle is producing white smoke, it's best to have it inspected as soon as possible.
