A new Nynja in the area

Moneybox, the problem with a simple rat trap vent is the potential to admit CO gases into the cabin. The exhaust system cuff or wrap is a far safer arrangement.

An engine fire would be one of the worst things that can happen while flying. Firewalls have to be fire proof.

If you have enough air temperature in the engine bay perhaps a simple Rattrap Vent would be a quick fix?

 

 I have fitted the factory and British approved system and through firewall valve setup.

Anything like that is hardly Likely to be stink free, is it?   Also on a cold day it would be lucky to be hot enough to do much.  I wouldn't take the Carbon Monoxide risk.  Nev

same system as blues in the texan i trained in. worked great and there was no smell at all.

Carbon Monoxide Poisoning is insidious. Where does your Oil tank Vent and how do you know there's absolutely NO  leaks from the exhaust system?  Nev

a well maintained engine will take care of leaks but we do have detectors as well.

you don't need a cabin heater to get carbon monoxide intrusion.

remember the dramas with jabirus until they figured out it was getting sucked into the cabin through the ventral fin cable outlet

The cabin generally runs at a Pressure Below ambient. The Oil tank has a breather. You haven't told me where that goes. It can even vent OIL in turbulence.  You can't guarantee you have No exhaust Leaks. Nev

Oil vents to fire wall bottom; away from engine bay.

Unfortunately Carbon Monoxide is a tasteless, odourless, and colourless gas, known as the "silent killer", because it replaces the oxygen in your bodys cells, and kills you very effectively and very quickly, with no warning. It has killed many people.

The smells from the exhaust you can normally smell, are the remnant gases from the combustion of the chemical constituents of the petrol. You do not necessarily need to smell those remnant gases smells, to be poisoned by CO.

i was referring to nevs comment that heaters smell.  did you not read my comment about carbon monoxide detectors. you and nev are convinced i am a complete dickhead and i can't change that. i will still sleep tonight. not from from carbon monoxide poisoning either.
