Exhaust smell

Get a carbon monoxide detector and show them proof .. as stated above check 2 vents on the back of the bunk the rubber deforms on them and they leak

 

Hmm. I had a Western Star. The rubber boot going through the firewall that covered the clutch linkage was all torn up. Maybe worth checking , assuming you have a manual tranny

 

Also - first, check all the things the previous posts here in this thread said.
Then,The search bar above right - will turn up other posts about this.
I do remember doing a pretty thorough rundown on this subject before.

 

Did you fix it?

 

From twenty seventeen - 2 yrs ago; and no reply?
It killed him!!!

 

2 year old thread but he posted it was fixed about 3 post above yours.

 

Driving through Houston this morning it hit 8 ppm while I was driving around Beltway 8 with the windows open. That was just the background CO pollution in the air.
