Foul odor under acceleration

Foul odor under acceleration
Seems to be present when A/C is off and accelerating at a brisk rate, coming through vents. Smell is strong to the point of causing a headache, I'm not able to identify what it smells like (not rotting or mildew, more like burning coolant or something) but it's quite strong requiring rolling down the windows.
I first noticed when I picked up the car from it's Inspection I service several months ago...the SA actually noticed while the car was idling in service area and took it back and put up on the lift but couldn't identify the source. Any thoughts??

If it's something that smells like it's from hot things...
you should look around the exhaust header and piples, look to insulation that crept out from behind the heat shields, and buring round belts, and from things like the alernator or A/C compressor.
Other places to look are where rotational friction can occure. Rear wheel bearings, half-shafts and the like.
If you still can't find it, get one of those little green pine trees to hang from your rear-view.
Good luck hunting it down.
One more thought. Get some rubber hose, and smell from specific locations. It may help localize the source...

I have a similar problem when accelerating hard--an odor that enters the cabin, but quickly dissipates. I notice the odor from other cars also and believe it's some byproduct of burning the oxygenated fuels we have here in New Mexico. I checked my exhaust and there's no leaks, but I wish it would go away...

I smell the smelly smell of something that smells smelly.

I might know what smell you're talking about. I usually get it when i'm accelarating hard. I think it's the clutch burning off! hahahaa! I had to replace my clutch lining after 20,000kms and the smell was very prominate after the new lining was in. But this doesn't happen when driving normally, only when driving hard. Now that it's worn in, the smell is minimal, but can be noticed sometimes.
Sometimes, the smell was so strong that I've had to open the sunroof and windows.
Would my description fit your scenario?

And clutch lining shouldn't burn off even when accelerating hard, seems like the spring isn't strong enough to keep it from slipping under full acceleration.
Unless your car is modded and the clutch just can't take the HP you're trying to put down

Some clarification could be used here and it can very well be same as the problem you had as I never heard of burning coolant being a very naseous smell.

Nothing much to my mods, well, nothing much to the engine. Just the basic few better sounding items. So i didn't see why it would wear off so soon.
In any case, I'll see how this new lining goes. If it wears off prematurely again, it's might probably be due to my driving (which i highly doubt as i drive mostly in the city). It'd be a good chance go change to a more uprated one. And a lightened flywheel since the tranny's off!

Seems odd that they wore off so fast considering that i wasn't driving aggressively ALL the time... Honest!
