The exhaust manifold is a single pipe that delivers the exhaust fumes from cylinders to the outside exhaust pipe. A leaking exhaust manifold will allow the fumes to circulate inside the cabin and so it must be avoided by looking for signs such as cracked pipe, loud noise, sputtering and others. You can find more details on how to detect leaks in your car's exhaust manifold, in the slides mentioned below.

1. How to Detect Leaks in Your Car's
Exhaust Manifold

2. The exhaust manifold is usually a single
pipe that delivers exhaust fumes from
cylinders to the outside exhaust pipe.

3. Exhaust fumes are harmful as they carry the
poisonous gas carbon monoxide, and a
leaking exhaust manifold may allow the gas
into the cabin of the car when the vents are
open.

4. The exhaust manifold is usually a single
pipe that delivers exhaust fumes from
cylinders to the outside exhaust pipe.

5. Here are the signs that indicate a leak in the
exhaust manifold of your car.

6. Cracked pipe

7. A cracked pipe in the exhaust manifold
rigging is a sure sign that it is leaking. The
rigging is underneath the car and you have
to use a lift in order to check the piping.

8. Once the piping is in full view, you should
check for cracks, and if you happen to find
any crack, take your car to the repair shop.

9. Volume of noise

10. If there is a leak, you will often hear an
increased noise volume near the engine
when you start the car.

11. You need to keep in mind that there is a
gasket that mediates between the engine
block and the actual exhaust manifold
piping.

12. Like the piping itself, the gasket goes
through the stress of a constant heating and
cooling cycle.

13. That is, if the crack is not visible in the pipe,
an indicator of a bad manifold could still
show in a warped gasket.

14. Hard acceleration

15. Sometimes when you step on the
accelerator, you can detect the sounds of the
exhaust fumes leaking through, but it is
very difficult to distinguish this noise from
that of the engine.

16. Also, noises from the engine could indicate
many other car problems, so it can be hard to
know whether this indicates a manifold
problem or not.

17. This method should likely be used only to
try to confirm your suspicions, after you
have already found another warning sign.

18. Sputtering

19. if you hear sputtering, then you know that
there is a leak somewhere. To make sure,
check the other symptoms to distinguish an
engine manifold leak from other leaks.

20. If this happens in conjunction with any of
these other problems, then you know what
you are dealing with for certain.

21. Exhaust fumes

22. Even though carbon monoxide is odorless,
other exhaust fumes are not, and if your
manifold is leaking, these odors will be
stronger than normal.

23. If your car seems to be producing more
noxious exhaust than usual, it may be time
to schedule an appointment at the repair
shop.

24. Finally

25. If you experience any of the above-
mentioned symptoms, then it is a guarantee
that there is a leak in your exhaust
manifold.

26. You should immediately take your car to an
automotive repair shop to fix the leak as it
affects the performance of the car.
