Just wanted to get an idea from the 582 flyers how many have a fully  

closed cowling in front?

I have the "Radial" look with a monster opening  in the front.  I have 

struggled with exhaust fumes getting into the  cockpit.  I have limited 

the airflow a bit but am considering closing  off all the front of 

cowling except around the prop shaft.  I have read  that the input 

pressure in the engine compartment may be too much with only  a little 

outlet at the bottom and no where for fumes to go.  C02  detector used to 

get pretty high 

  

 Hi ! Jareds,

                        Rex here from Australia. I have a MKIV with cowling like yours and a 582.  Occasionally I have noticed fumes on climb out only. I put in a cheap detector  after flying with a friend that has a notorious nose for CO2. In fact he is our  club flying instructor and most highly respect him. Anyway after putting in this  cheap detector about six months ago I haven't noticed any fumes. it seems  to have scared them off. Also despite looking a few times I've not seen any  change in colour on the detector either. I've always cosidered the fumes  momentary and insignificant but my friend did make me a little nervous and so I  put in the detector to check.  I have Grove gear and so no holes there and  as I say have only rarely noticed fumes on climb out  only.

Just a small correction here.  Isn't it  supposed to be CO (carbon monoxide)?  I think CO2 is carbon  dioxide.

While it may simply be symantics, we need to clarify a couple of things. First off, it is CO that is the silent killer. Secondly as we are all aware of, it is colorless and odorless. Just because you can smell the incomplete combustion in the cockpit, doesn't necessarily mean there is a CO problem. It is however an annoyance that no one wants to fly with. You have made a wise choice in installing a CO detector. No one should leave the ground without one.

Incomplete combustion is the correct word, Gary. Because CO2 is as colourless and odorless as CO. Otherwise our breath would smell like an exhaust pipe! 

.. well, at least, to other humans, because mosquitoes can detect our CO2 release. So, next time one of those little bugger is bothering your, hold your breath to see which one of the two will faint first!

Never leave without mine, Sir!

Michel,

I didn't know lutefisk and lefse could make your breath smell like that! If I remember correctly from my physiology days, CO attaches to the red blood cells something on the order of 200 times quicker than oxygen thereby suffocating the cells thru hypoxia internally. In a higher concentration, CO2 will also kill based external hypoxia (lowered atmospheric oxygen level). Just a thought. By the way, I could never get past the smell to dive into a plate of lutefisk. The lefse on the other hand is A-OK. Bring on the mosquitos!!

I feel I should put in my two cents worth.  I put 4 people, including 

myself, in the hospital from carbon monoxide poisoning years ago in Chico, 

California.  I experienced condensate on the windshield on takeoff and 

opened the defrost vent, left it open until we realized something was wrong 

and altogether flew 2  hours before landing in Chico.  It turned out the 

muffler had a large split and dumped a lot of the exhaust into the cabin. 

We were flying at 9500 feet with icing clouds above and mountains below and 

not a clear idea of were we were going to set it down.



If you fly with an exhaust system heater and have a closed cabin, get one of 

the electronic CO sensors that will warn you audibly when CO is detected.



The heater in my Kitfox works from hot water and the ventilation makes it 

practically useless.

Nor can I, Gary. I guess you had to try it just to prove your 

Scandinavian descent. It's silly because fresh cod is just as Norwegian 

and it is delicious.

To the benefit of the list: lutefisk is cod marinated in caustic soda. 

It then turns into a jelly-like, tasteless substance. Now, why would 

anyone come with such a silly idea? Apparently in the 17th or 18th 

century, the Norwegian town of Bergen burnt down and a lot of stock 

fish (dried and salted cod) was found in the ruins of the warehouses on 

the docks. Fish, plus ashes, plus water, makes a very alkaline 

combination similar to caustic soda. The poor people of the town found 

that, after proper rinsing in fresh water, it was still eatable and a 

new tradition was born.

Today, lutefisk is seeing a renaissance mostly among men's club when 

they gather in the weeks preceding Christmas, to eat that disgusting 

dish with a lot of beer and aquavit, our local snaps. I believe that if 

you drink enough ... you can eat just anything! 



Cheers,

Michel
