How To Know Your Car’s Head Gasket Has Blown

The car’s engine is a wonderful, yet complicated air pump that runs on a mixture of gasoline, oil, and coolant. However, none of the three fluids are allowed to mix in the engine, and if they do, then there’s a likelihood that your engine’s head gasket is blown. 

But will you know when this happens? In this article, we take you through how to monitor and pay attention to your vehicle’s engine and head gasket.

What is an Engine Head Gasket?

A head gasket is a “ringed panel that fits in between an engine’s cylinder head and block.” The head gasket acts as a barrier between the coolant channels and prevents coolant from leaking into the cylinder chambers. 

Due to the head gasket’s location, it faces a full range of temperatures and pressures, so over time, it’s likely to end up leaking or cracking, which leads it to “blow,” or fail.

Easy Signs to Identify a Blown Head Gasket

If your car has a leaking head gasket, there are some symptoms that will let you know there’s an issue. Here are the most common indicators that your engine’s head gasket has failed:

• An external leak between the engine block and cylinder head, typically around the exhaust manifold.
• White smoke from the exhaust pipe
• An overheating engine is another symptom, however, it can mean a range of issues
• Cylinder misfire
• A frothy white substance underneath your oil cap, which is the result of coolant and oil mixing

The first indication would be the check engine light suddenly coming on and the most likely the temperature gauge reading that the engine is overheating. If that ever happens, ensure to stop your car immediately and shut off the engine to let it cool down.

Should I Drive My Car When the Head Gasket Has Blown?

When the head gasket blows, the engine loses a lot of pressure and its cylinders won’t be operating with enough force to produce power, so you will experience a lot of power loss. 

Additionally, since coolant and oil will likely be leaking into the combustion chamber, important parts of the engine like the crankshaft and bearings won’t be lubricated properly and in turn will experience a lot of friction and undergo more damage.

A blown head gasket can lead to more damaged engine internals if you happen to drive the car, so it’s best to not drive it and call a tow truck to have it towed to a professional mechanic shop.

How Much Does it Cost to Replace a Head Gasket in Nigeria?

The cost to replace a head gasket can vary greatly as many automotive mechanics have different parts costs. Also, every car is different, so some engines might be easier to work on than others. 

If you have the tools and proper experience, then you can always tackle the job yourself, just keep in mind that it’s a really long and tedious job to work on.
