Clogged Catalytic Converter

A clogged catalytic converter can lead to various problems in your vehicle’s exhaust system. One of the most common symptoms is a decrease in engine performance. Another indication is an increase in engine temperature. These issues arise due to the restricted flow of exhaust gases.

There are several causes for a clogged catalytic converter, such as excessive carbon buildup or the presence of foreign materials. To diagnose this problem, you can perform a simple test by tapping on the converter and listening for any rattling sounds.

Additionally, you can check the oxygen sensor readings using a diagnostic tool. If the readings are abnormal, it may indicate a clogged catalytic converter. Therefore, it is crucial to address this issue promptly to ensure the proper functioning of your vehicle’s exhaust system.

Leaking Exhaust Manifold

Leaking exhaust manifolds can cause a range of issues for your vehicle. Signs of a leaking exhaust manifold include loud noises, decreased power, and increased exhaust emissions. Reasons behind a leaking exhaust manifold can vary, but common culprits include worn gaskets, cracked manifolds, or loose bolts.

To diagnose a leaking exhaust manifold, start by inspecting the manifold for any visible cracks or damage. Use a flashlight to check for leaks around the gaskets and listen for any unusual noises. You can also perform a smoke test to identify the exact location of the leak.

Make sure to address a leaking exhaust manifold promptly to prevent further damage to your engine and ensure your vehicle runs smoothly. Avoid delays and costly repairs by being proactive and addressing any exhaust problems as soon as they arise.
