This would depend on your nose. A bad CMP sensor may cause improper burning of the fuel and can give a smell out the tailpipe. Will the CMP smell? Never. A Ford camshaft syncronizer will squeek and could cause a metallic burning smell.
If your talking about cars... If you smell a burning smell, or your red battery light comes on then i would get your alternator checked out!
you have a bad heater core in your vehicle
head gaskets are probably bad and leaking oil onto crossover pipe .
Bad heater core.
rough shifting of gears, slipping of gears, a burning smell from the engine may be symptoms of a bad trans axle
Your vagina is supposed to have a scent: it should smell musky but clean and will change with hormonal changes throughout your menstrual cycle and when aroused. As long as it doesn't smell bad it's not a problem, but a bad odour such as a fishy smell or a smell like bread can be a sign of a temporary imbalance in flora or a full-blown vaginal infection. Itching and burning are common during a yeast infection, but bad odour alone is a sign of an issue so see your doctor if you experience this.
heater core is bad may need a coolant flush
Electrical fire or bad bearings. The alternator is probably toast. Buy a new one.
Well i don't. I think the real question is why do yousmell burning feathers. I can't even imagine what burning feathers smell like.It smells terrible, I regularly smell burning feathers, paint, and a strong perfume or potpourri that nobody else around me can smell.
Yes it is because of the fact once it stops it is going to leave a burnted smell and could even explode.
because you are exercising and all that sweat that comes from body fat that you are burning tends to smells pretty bad.
