The exhaust manifold of the vehicle’s engine is responsible for collecting the exhaust gases. It is bolted to the cylinder head and sealed by a stuff known as Exhaust Manifold Gasket. An exhaust manifold gasket is an important seal that should be inspected from time to time. Its failure can have a significant knock-on effect on your speed machine. That’s why being able to address the symptoms of failure can save your time and wallet by allowing you to repair the things timely.

2. The exhaust manifold helps to collect the byproducts of
internal combustion and send them to a common exhaust
pipe.

3. Exhaust manifold gasket seals the gap between the
cylinder head and the exhaust manifold.

4. Extreme temperature, pressures, coolant and different
types of contaminants could damage the gasket.

5. Cracks or any kinds of deformities in the exhaust
manifold gasket might adversely affect the compression
inside the engine which inturn affects its power output.

6. So, signs which show that the exhaust manifold gasket has
defects should not be overlooked.

7. SIGNS OF A DEFECTIVE
EXHAUST MANIFOLD
GASKET

8. Appearance of abnormal noise from the engine and exhaust
system is the first and foremost sign of a defective
exhaust manifold gasket.
ABNORMAL NOISE
AND SMELL

9. Cracks or leaks in the exhaust manifold or manifold
gasket could be responsible for the appearance of hissing
noise.

10. The noise increases with the acceleration.

11. Besides, a burning smell might appear from the engine
bay.

12. POOR
PERFORMANCE BY
THE ENGINE
Internal combustion engines are supposed to be closed
systems to run efficiently without any loss of power.

13. However, cracks or leaks in any part of the engine
including intake or exhaust manifold might adversely
affect its performance.

14. Such cracks or leaks might adversely affect compression
of the engine and thus affect the power output of the
engine.

15. Different types of sensors located in the intake
manifold, exhaust manifold and exhaust system provide
data to the engine control unit.
POOR FUEL
ECONOMY

16. The ECU uses such data to regulate the fuel to air ratio
inside the combustion chamber.

17. Errors in the data provided by the sensors due to the
cracks or leaks in above mentioned components might have
disastrous consequences.

18. BOTTOM LINE

19. Any kind of leakage in the exhaust manifold gasket might
adversely affect the efficiency of an engine.

20. So, signs which show that the manifold gasket has defects
should not be ignored.

21. It should be replaced immediately to optimize the
performance of the engine.
