Boeing has been ignoring this problem far too long. avherald has a report of bad smells in the cockpit and cabin, and diversions caused thereby, every week. Seems like the courts are the only solution left.

I read that during WWI a lot of the fighter plane engines (which generated all of 100hp) used castor oil as a lubricant. The exhaust from which would then hit the pilot in the face.

not exactly toxic per se, but the $hits nonetheless.

In future designs cabin air will probably be produced by an electric pressurization/HVAC unit like the 787. Or at least will have some more robust filters.

Jet-turbine oil contains Tri-Cresyl Phosphate as a stabilizing additive. The problem: it acts like other organophosphates....it’s a nerve-agent.
If the front bearing-seals leak in a jet engine, that oil will be compressed with the air, turning to vapor, and delivered via normal bleed to the Packs...and the cabin.
The best solution would be to find a substitute additive that is not a nerve agent. Because stopping ALL oil leaks is mechanically impossible.
But it may be there is no other alternative.

Getting rid of certain additives might be good, but honestly I don't want to breath ANY complex hydrocarbons (especially after they've been cooked). I believe filters are a viable option, but they would expensive and heavy enough enough that it would take regulatory intervention to get them into widespread use (like fuel tank inerting retro-fits).

The B-707 used a turbocompressor for A/C (the small inlet above the cowl). It was driven by 16th stage bleed air, but provided outside air instead of bleed air to the cabin.
