My '86 22RE exhaust smells like gunpowder(?)

I use a variety of fuel brands, usually Hess but occasionally Sunoco or
Sheetz. Maybe due to the gas/oil situation and the less restrictive EPA regs
the gas is less refined and or less additives. BTW, I did notice that when I
ran a fuel injector cleaner/octane booster through a tank there was no
smell.

you dont say that you repaired the exhaust system, is the tail pipe back on
and in the same position as before? The pipe may be placing the exhaust in a
different air flow stream and you are noticing it now. However you shouldn't
be driving around with the tailgate open as exhaust gases in the cab can
kill you! The sulphur smell is normally there but not too strong, the fuel
batch in your area might be the reason.

What you are smelling is sulpher in the fuel and even if you change to
low sulpher fuel breifly it will still stick for a while. THe injector
cleaner compound must modified the sulpher content of fuel in a way
that it does not react/burn the same way.

Another possible source of sulphur smell is the battery.

I once had a voltage regulator go bad. The function it has of stopping the
alternator from overcharging the battery quit working. So it was constantly
overcharging and overheating the battery, and boy did it stink when the
battery really started to get toasted.

Picky detail alert! CO is dangerous as it will pick the oxygen out of your
blood, becoming dangerous above about 50ppm.

CO2 is harmless unless you believe in human powered global warming, or
drink too much Coke etc...

But your senior point, watch out for unwanted gases coming in the back, is
valid. Headaches are a first warning sign.

Make that headaches that do not go away. Carbon monoxide poising treatment requires a decompression chamber.

Picky detail error alert: Carbon Monoxide has a higher affinity for
Hemoglobin than regular Oxygen molecules at normal atmospheric
pressure, and CO when inhaled in significant concentrations will glom
onto all the available Oxygen carrying receptors in your blood.

You can be breathing normal air or even high concentration Oxygen
and still die, if a critical percentage of the oxygen receptors in
your blood already have a Carbon Monoxide molecule attached - and
under normal conditions they don't let go without a fight. If you get
above that critical level you need rapid medical intervention.

CO2 isn't nearly as dangerous as CO. Too much inhaled Carbon
Dioxide can get your bloodstream to go acidic and throw your internal
chemistry way out of whack, but it takes a much higher concentration.
And it isn't immediately life threatening if you get out to clear air,
though the acidosis can be a bunch of trouble.

Too much Carbon Monoxide (or Dioxide) can also get the autonomous
respiratory control center in the brainstem all out of whack. You
have to monitor respiratory rate and volume while getting the victim
to help, and you might have to bag 'em (ventilator or rescue
breathing) if it gets really bad.

Absolutely.

Another nit that needs picking: Wrong direction of pressure change
- Decompression is vacuum...

You need a hyperbaric or compression chamber with pure Oxygen
available by mask for the patient to breathe. (100% Oxygen in the
chamber atmosphere can be very bad - remember the Apollo 1 fire...)
You have to force the hemoglobin to let go of the Carbon Monoxide
molecules so it can start carrying Oxygen molecules again.

Can I get an Amen, Natalie? I think I remember a _few_ things from
two EMT Certs and a bunch of overlapping ARC Standard, Advanced and
Mountaineering Advanced First Aid certs...

Bruce;

My interest was in the equating of CO and CO2 as "bad". Your EMT view is
accurate.

CO2 is being denigrated by the echo-wackos. CO2 is vital to life. CO is a
toxin and very dangerous. CO2 is what we exhale. Plant life breaths it
in. It is not a poison. Whether its dangerous to the planet has only been
established in AlGore's filmworld. Real scientists, contrary to popular
opinion, don't back the view that CO2 is dangerous to the ozone layer or
anything else.

CO2 drawn in through the back window can not hurt you. You'd have to
displace a lot of oxygen (and nitrogen) to create an effect. Unlike CO2,
CO is dangerous in parts per million. It is an active poison to humans.


As I said, this is picky, but I do get a bit tired of the fear-mongering
from the so-called greens.

Of course, nobody asked me, and this point is periphreal to the
subject..lol.

Not a one brand man so I don't see that as a culprit. Tail pipe broke
off at the back of the muffler. So while I may be catching the odor if
it was fuel related I should be smelling it from other cars as well.

Somebody mentioned a failing converter. 186Kmi. Might be time.

The broken tailpipe is allowing the odor to enter the cabin. You should
consider getting that taken care of to avoid carbon monoxide poisoning.

It is possible that the converter is failing but a bad converter will not
make the exhaust smell like gunpowder. The exhaust from pre-converter cars
did not smell like gunpowder.

After you get the engine good and warmed up, like after a highway run, open
the hood on a dark night and make sure the exhaust manifold is not glowing
red. If it is, it may be cracked or leaking. Also take a look at the
converter and make sure it is not glowing. During the day, inspect the
exhaust manifold for leaks and check the condition of the air filter.

I'll check the manifold.

A 22re w/ 180kmiles. Not exactly:(
