    Default 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

    KAP

    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.

    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.

    Comment:

    I went on to that forum first and they say it is the down tube on the exhaust---ie... the clamps are loose.

    Then another forum says seals around the back part of the hood.

    It smells like exhaust more than unburned fuel and it does it intermittently.

    I will haul it to the dealer tomorrow and see whats up--- my wife likes driving the truck but she is 7.5 months along and I do not want her driving it and breathing those fumes--- causes me a great deal of concern.

    Thanks

    I will let you know what the outcome is once all is said and done.

    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.

    Eureka:

    Cracked down pipe on exhaust they will replace the whole thing on Monday clamps and all.

    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.

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

    Dare to be different, if it turns out great you can claim you planned it that way.

    Comment:

    If you have diesel fumes in your cab it is a cracked down pipe. We have had the Silverado back now for over a week and no fumes or smell in the interior of the truck.

    I wanted to follow-up for those Silverado Duramax owners who may have this problem.

    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.
