Does a bad manifold gasket make loud noise and burn lot of gas?

Yes, a bad manifold gasket can cause a loud noise and burn a lot of gas. The manifold gasket is a seal between the engine manifold and the cylinder head. When it fails, it can cause a vacuum leak, which can lead to a number of problems, including:

* Loud noise: The vacuum leak can cause the engine to run rough and make a loud noise. This is because the air/fuel mixture is not being properly combusted, which can cause the engine to stall or backfire.

* Burning a lot of gas: The vacuum leak can also cause the engine to burn a lot of gas. This is because the engine is not able to properly control the air/fuel mixture, which can lead to a rich mixture that burns more fuel.

* Other problems: A bad manifold gasket can also lead to other problems, such as overheating and engine damage. If you suspect that your manifold gasket has failed, it is important to have it repaired as soon as possible.
