Strange smell coming from the engine after being towed

[johnboy2]

I didn't see where you said what braking system your using it could be coming from that. I know my brskemaster discharges in the car so I'm getting some odor from the air system on the coach that goes away shortly after using the car.

I have a similar condition with my toad, a Chevy Tracker. Don't smell it until we drive the toad, not upon disconnecting after towing. After driving it a while, everything picked up towing burns off and I can't smell it any more.

I do get some smelly stuff after towing 4 down behind the DP. I've written it off to road crap and if I do some detergent spray and wash the radiator and engine compartment routine when I get to where I'am going I don't get that stink ing feeling. Magic!!

This smell is common for lots of folks either dolly towing or 4-down. Noticed it the first time I towed my Murano with my Excursion and now get it with my CRV when towed with my Discovery.

I think it's rubber,road grit etc getting deposited on the engine and exhaust system of the Toad. When you disconnect and start your car it starts burning off and lasts anywhere from an hour or two to a couple of days.

I get the same thing on my CR-V sometimes. It is road debree burning off. You get the same stuff when you drive but it is burned off as it lands and doesn't have time to accumulate as when you tow.

Could possibly be oil and tire rubber from the road surface sticking to the Catalytic Converter and exhaust pipe.
See: http://www.irv2.com/forums/f85/hot-o...ep-187493.html

Upon start, the toad's Catalytic Converter gets hot - fast...so hot that (we all should know) it can start a grass fire.

It is most common in the west where lower rain levels rarely clean the roadway.
Can Happen to flat towed or dolly towed (like ours).

Safe travels

Hello Friends!!! Thanks for the advice on this matter that is why I love this forum!!!! It now make sense after towing the toad for several thousand of miles why I get this smell now I do not have to worry that something funny is going on with the Jeep! Like I had stated before this smell only happens after I start the engine on the toad there is no smell while it's being towed or when I disconnect it from the MH, again THANKS for the advice!!

You learn something every day on the forum.

From the dealer towing four down requires transfer case in neutral not the tranny. It sounds like he is putting the tranny in neutral and the trans is turning the engine and fluids are being sucked in to vacuum places and sit there until the engine runs for a time.
