What is an exhaust manifold gasket?
The exhaust manifold gasket connects the exhaust manifold to the cylinder head surface, which prevents exhaust leaks in the system. The constant expansion and contraction of the components due to heat exposure can cause leaks over time.
When should I replace the exhaust manifold gasket on my car?
Look out for the following signs of a bad exhaust manifold gasket:
Exhaust leaks: You’ll notice a hissing or clicking sound from your engine compartment if your exhaust manifold is leaking due to a damaged gasket.
Check engine light: Your car’s engine control unit (ECU) will pick up cues from your oxygen sensor if your exhaust manifold gasket is malfunctioning. As a result, you may notice your check engine light illuminating.
Exhaust fumes: If you notice a smell similar to burning plastic, your exhaust system may be leaking fumes due to a malfunctioning exhaust manifold gasket.
Poor engine performance: Your engine will have a lower power output if your exhaust manifold gasket is damaged.
Lower fuel efficiency: A failing exhaust manifold gasket can lead to higher fuel consumption and lower fuel economy.
Emissions test failure: Your vehicle will not pass an emissions test if your exhaust manifold gasket is damaged and causing exhaust leaks.
Visible damage: If visually inspected, you may notice cracks or corrosion on your exhaust manifold gasket.
High mileage: Your exhaust manifold gasket is prone to wear and tear over time. If your vehicle has a lot of miles on its odometer, you should have your exhaust system inspected just in case.
How often should an exhaust manifold gasket be replaced?
There aren’t precise replacement intervals for exhaust manifold gaskets, but they are subject to wear and tear from extreme heat exposure. Your best option is to routinely inspect your vehicle and engine to ensure your exhaust system, including the manifold gasket, are operating correctly.
Can I replace my exhaust manifold gasket myself?
The process to replace an exhaust manifold gasket is complex and involves a comprehensive understanding of car engines. To ensure the job is done correctly, you should take your vehicle to a certified mechanic.
