I think he thinks it could be an exhaust leak forward of the firewall.

 

Lolol

 

Is your car loud? Does it smell bad when you start it up and stand outside the car near the front end?

Open your hood and smell around out there with it running. Exhaust leaks before the Cats tend to smell bad because it's raw exhaust that's escaping the system.

I actually just fixed a header leak on my mom's Accord this past weekend. Not fun. The studs on the headers were rusted off. She was getting an exhaust smell in the cabin prior to the fix.
