Hey guy,
When I open the engine bay cover (when the engine is operating), I can smell a tiny bit of exhaust fume (only when I dig my head inside). Is this normal? Thanks!
If it is in the engine bay, I would recommend inspecting your Headers for cracks. While you're under the car, I would also scope your Cats to ensure there hasn't been a failure.

Shoot us a PM if we can help in any way!

What is meant by "tiny bit" and how far inside the engine compartment are you sticking your head?

One test you could run is to have a second person block the exhaust tips and see if you can then hear exhaust escaping
from some opening closer to the engine.


You have provided no background on your vehicle:

year of manufacture​
number of miles on the vehicle​
and exhaust work completed - and if so, when​
any off road excursions or other activities/events that would have damaged the vehicle's exhaust system, resulting in a leak​
how long you've owned this vehicle​
was there no exhaust smell previously​


While exhaust leaks are important to address, what is described above does little to convince me there exists a serious problem.

Is it possible that, with the engine running and the hood open, and possibly a breeze, some exhaust is making its way underneath
the vehicle and out through the open hood?


Are we counting dancing angels? I hope not.
