Apply sealant around the cracks or holes in your exhaust system using a high-quality sealant. Do this on all areas where you found engine fumes escaping into the atmosphere, not being pushed out through your tailpipe.

Step 5. Check the Leak Again:

Check for leaks again to see if you’ve fixed the problem. If you’re still leaking engine fumes, repeat this process until you find all of the holes and cracks in your exhaust system where engine fumes are escaping into the atmosphere instead of being pushed out through your tailpipe.

Tip 6. Check for any exhaust leaks or signs of fluid seeping out around the sealant. If there are no leaks, turn off your car’s engine and allow it to cool down again before doing anything else.
