Exhaust Smell Inside Cab

[Busterboy1]

I have started getting an exhaust smell inside the cab after a run down the interstate. Once I run several miles and then stop I get a diesel exhaust smell but not while moving. After it goes through the "Cleaning Exhaust Filter" cycle the fumes are so bad I have to roll the windows down. Anybody have any suggestions?
P.S. Sorry if this has been covered previously, guess I missed it.

I found the previous post, if I hadn't fat fingered the search I would have found it before making the post.

I too have horrible diesel smell on my 2011 F250 in fact it is at dealer now for this. Very noticable sitting at red light with vent on, to the point it will make me start coughing and gagging. So far Ford is stating normal, now for some reason they are going to change out my oil PAN???? That is what I was told.

Mr. B I fixed mine last night after making the post. I did the search again and found several post about it and a link with some pics. It took me about 5 minutes to fix and that included walking to the tool box and getting the wrench. If the "Oil Pan" replacement doesnt help with the exhaust smell just repost here and I will talk you through it. All you need is a single 5/8 in. open end wrench. Good Luck with that oil pan!!!! LOL

[Mr. B]

Yes, let me know what you did to repair yours, I can't imagine oil pan fixing this.

No problem Mr. B, Look under the truck on the passenger side behind the front tire. You will see an exhaust down pipe running from the top of the engine down between the engine and the firewall. Up close to the top of that pipe there is a line that runs into the exhaust pipe with a brass colored nut on the fitting that secures the line to the exhaust pipe. That nut was completely loose on my truck. I tightened it several rounds by hand then put a wrench on it and snugged it down. It is a long reach up to the nut but there was enough room for me to raise up on one elbow and reach up to the nut with other hand to get it finger tight before putting the wrench on it. It took a 5/8 in. wrench to tighten it.
Let me know if it was loose on your truck too.
GOOD LUCK!!!!

Thanks, I will check it out when I get back from Dealer.

Took my truck in for the exact same issue as op and what busterboy1 said is exactly what was wrong with mine. The dealer said it is very common.

Sorry guys I've been out of town, the solution to the problem I described to Mr. B was correct. I tightened the nut and I completely eliminated the exhaust smell. Very simple fix and I didn't have to mess with taking it to the dealer.
