Rear Window Open and too much exhaust smell

[Riser]

I can honestly say I've only smelled fumes a handful of times. And the truck was in open loop each time (not at operating temperature), which is to be expected. And I'm willing to bet if you measured actual Hydrocarbons in a modern car, they would be low.

The real threat from exhaust gases is and always will be CO. If you really want to start analyzing potentially hazardous materials in a vehicle, you could find several, depending on how hard you look. Look at all of the different materials in your interior. Didn't a report come out that identified potentially toxic adhesives and sealers used on the plastics (hence, the new car smell?)

You probably come into contact with hazardous chemicals more from your drinking water, then you do the back window of your T4R. Ask your local state health department about all of the disinfection byproducts they find in city water.

I'm off to go play with some lead toys

• CARBON DIOXIDE
In recent years, the U.S. Environmental Protection Agency (EPA) has started to
view carbon dioxide, a product of “perfect” combustion, as a pollution concern.
Carbon dioxide does not directly impair human health, but it is a “greenhouse
gas” that traps the earth’s heat and contributes to the potential for global
warming

Harper, so what you are saying is that with the low pressure created by the open rear hatch window, sucking in all of those cool exhaust by-products you mention, I could potentially grow a vegetable garden in the cargo area, preferably corn. This vehicle is already on a 10% ethanol diet so it could help feed itself.

No shortage of "fertilizer" in that cargo compartment.


Lightening your mood back.

No more fumes

I went ahead and had the tailpipe rerouted to exit the passanger side behind the mudflap as a couple of others have done here. No maganflow or anything cool or special just the 2.5" pipe into a nice chrome tip that is also welded. The results were immediate. I can honestly now say that this has taken care of my sucked in exhaust problem. Also it won't be mistaken for a Rav4 from behind.

All hatchback and station wagon vehicle body types will draw up whatever is behind them and deposit it on the back of the vehicle because of the lower pressure that forms behind the vehicle as it speeds up. Trucks with cube boxes etc will do this as well. It's how air flows, and that's why there is a wiper back there to remove road spray and whatever else gets on the vehicle from being sucked up behind it.

:iagree:

I've had several 4Runners (87, 92, 97 & now 2011) opening the back window on all of them would result in exhaust odor in the vehicle. It's the reason I don't drive with it open unless needed to transport things like lumber, etc. I think some may be more sensitive to it than others.

Just wanted to see if the side exit exhaust fixed the fumes backing up into cargo department long term. I have a 2003 and can not use the back window due to fumes as well. If this is the fix, I'll remedy this weekend.

The best $35 I spent. I stopped by a muffler shop and he rerouted it 90 degrees. totally worth it.
