FYI Exhaust smell in cab

[ScottBrown]

I performed this little fix yesterday, I removed the wiper blades, then the plastic cowel over the wiper motor. Noticed the passenger side of cab had foil tape over the oval cut out, the drivers side did not . I used the foil tape and covered the oval cut out on the drivers side of the cab. In the middle of the cowel intake box there was a black rubber gromet that I covered with the tape. put everything back together took for a test run no smell in cab when truck is stopped and running.

I did not cover up anything else on the cowel box. The heater works great with the oval hole covered up. -2f when testing.

I'm thinking if the breather hose is routed closer to the air filter, then the fumes could be drawn in and burned. There shouldn't be any danger of a runaway, but that should be checked out first.



Wow! And everybody was worried about egr on the 04. 5s. Now you're making your own! Almost. You're using blowby, instead of exhaust. That will make your turbo compressor vanes nice and sticky and ready to hold the dust.

The only thing I did was close off the oval cutout. No reroute air filter blowby turbo compressor sticky ca ca

ScottBrown,



Are you sure you just didn't block off the outside vent? which is what you do when you put the heater control to re-circ... when I run in the recirculate mode I don't get the smell, only when it's bringing outside air do I get it.

I'm thinking of routing close to the filter so that the fumes go thru the filter. If it's down low in the box, the oil and gunk should stay off the filter. (I hope)

I dont smell squat of anything unusal. Wife says she does some. So I have NO problem!

 

[ScottBrown]

I t probably is the air vent ,it is the on on the drivers side about a 5 " oval shaped. The heater still forces the air in form the other openings, I went for another test ride last nite no smell as of yet

 

[NSperduto]

Did you completely close the oval cut out and did you cover both of them. THere are two on the drivers side, one low and rear and one high and front.

The one on the pass side was factory covered with the foil weather sealant, I covered the one on the drivers side only, also in the middle of the tray was a rubber gromet that let air in , I taped that off also.

If yours came with foil tape over the upper hole on the passenger side, I am guessing that Dodge must be figuring out the smell problem. I have a 11/2002 build date and there was no foil only a rubber scutter door cover on the passenger side and neither on the drivers side.



Today I taped the two upper holes completely and tried to get another rubber scutter door cover at the dealer. The dealer says part is not anywhere in the chain to get. period.



Tried one local junkyard said there were some new ones in Buckley but figured I could make my own faster than driving 75 miles. Put it all back together and tested to make sure water could still get out AOK there have not had a chance to test for smell yet.



The dealer told me that they have been replacing the rubber seal between the cowl and hood with complaints of smell, they were very interested in me finding some rather large holes between the engine and the cowl airbox I told them I would keep them posted.



If this doesn't work I have already started looking into the breather hose and routing it to behind the drivers front wheel.



Next Monday the dealer will install the new weighted power steering hose and they will check for abnormal blowby, if so they will adjust the valves which normally they don't do until 100K.

I worked on fixing that factory seal by the cowling. I saw there was a slight gap, thought that could be the problem. I took some 1" foam pipe insulation, the type with the split in it, and just laid it over the factory weather stripping.



Made no difference

Absolutely unbeleivable I'm sure glade I'm only doing a 2 day test drive on this truck. At first I thought it was new engine burn off but after 50 miles I thought... "This isn’t right" so I did a search on the ole TDR and look what I found. This is not good. Where the heck is the breather tube on this thing anyway?

 

[EMD-Run8]

Oh for crying out loud already!!! Turn the flamin' recirculating air control to any "recirculate" position and it won't do it!!!! At least mine doesn't.

I extended the breather hose to just below the drivers door were the transmission mounts attaches to the frame. I now very rarely get smell in the cab. I definantly feel the breather hose is the main source of the smell I just change the oil and can get a strong wiff when I get out my door.





I attached a link to my thread with pictures to help you guys out this is a fairly easy fix and cost less than 10 bucks worth of material.

You guys must have good sniffers or real smelly trucks. Very rarely do I smell diesel fumes,mainly once in a while on cold start and pull up my driveway and stop and sometimes I catch a small whiff of it. Wife is has a good sniffer never has commented at all on it.

 

[Cliffman]

DPKetchum, I'd be very curious to see if the factory forgot to install the plugs in your truck. Also, I see in your sig that you have "Smoke vent shades". What the heck is that?



ttreibel, I see by your post that the breather hose is coming down on the drivers side next to the starter. I that where it comes down from the factory?

 

[DPKetchum]

Best I can tell all my plugs are in. I looked and found no tape. I understand you may be thinking plugs are missing from cowl area and rightfully so. I have SMOKE colored window vents shades on all four windows.

I don't get any smell like that on my t ruck either. These guys have blowby problems. They're not smelling diesel smoke.
