Fumes Duramax

Hey anyone know why the cab get's inundated with diesel fumes today I was choking from all the fumes.

It happens intermittently I called the Chevrolet dealer and the Service Department knows nothing about such a problem which is weird because several people complained previously about the same problem.

Can any PB members shed some light on this issue.

Thanks

Sorry forgot technical info. 2008 HD 2500 4x4--- Duramax w Allison no engine mods---no exhaust mods--- prompt and regular service on all fluids and filters.

Very Strange. .. Take it to the dealer, Its under warranty.
For future reference, ask your questions on thedieselplace.com. this is the best place for Duramax questions.

Hasn't happened on mine. About the only thing I could even suggest would be look at the filter - especially if you have had it serviced (or done it yourself) recently. If the O-ring gets bumped out of it's seat, there can be a diesel leak right near the intake for the ventillation system for the cab.

If you're speaking of exhaust fumes, you must have an exhaust leak in the system somewhere in front of the muffler. Get it fixed ASAP. If you are speaking of raw fuel, you would surely see leaks when parked. That also would need immediate attention. Both would be covered under warranty.

I have had three Duramax, Crew Cab Duallys without as much as a single problem.

LMMs (07.5 and up) have completely different injectors. They are not like the old ones and probably won't ever need to be replaced.

It is nice when the customer does the TSB research for the service writer who by the way is a good friend of the family.

I will let you know if all problemos are cured.

Wow.
Glad to hear you got that taken care of.

very good advise lotta guys jack up the water in fuel sensor oring as well, see that real often.

Nice to know.

My exh temp is down 200* from normal, so I shouldn't have any cracking issues.

Well, yes and no. I agree with IDEA behind it and I did enjoy no smoke / exh smell (other than during REGEN). Let's face it; you can stick your head right by the tailpipe of a new (stock) diesel and not be offended at all.

However, when I saw the EGTs (not even during REGEN) and crappy mileage, I decided to at least try it. Boy, am I glad I did. It runs like a whole different truck. Dealership has no problems with the mods, as long as I don't abuse the truck (which would show).

I just hope in the future there will be a DPF system that doesn't take so much power to run.
