I figured that the part is manufactured in-house since the seem welds and black paint closely resembles that on the charged air heat exchanger next to it.

I suppose that is possible, with a giant oil reservoir and it venting to atmosphere instead of into the intake manifold. But the 3S-GTE engine is port injected and so it has less need for a catch can.

Lubrication system header tank for the flexi-drive?  

 

Crank case breather, surely?

I when through so of there episodes to see if they installed a PCV or catch can, I did not find anything so best guess is that it is a catch can unless somebody finds more information.

Given its proximity to the Safety Turbo, I would guess it's a catch can for the blow-off valve. Perhaps required for Track Days?

I've heard (no personal experience obviously) that people used to vent their crank cases under the car when they had perhaps bought a Pipercross air filter the base plate of which had no provision for connection to the crank case output. I think the logic went along the lines of, "Why would you want to add warm oily air to your combustion?". On top of which it would involve doing highly complex drilling and brazing beyond the skill set of the sort of 20-somethings that engaged in this kind of activity. Allegedly.

From a personal point of view, I would think this kind of behaviour to be highly irresponsible - perhaps nearly as bad as owning and using a particulate spewing diesel - and should of course be condemned. Or reported to the nearest MOT testing station lawyer.
Clearly if BOM were to be catching such emissions and disposing of them safely then this should be applauded.


Perhaps the box contains nothing but lead, in an attempt to bring the CoG closer to the centreline of the car? Whatever it is, I think we should be told. The public has a right to know.

Thanks for the translations. You missed one for us dimwits (retards): PCV? Plenum Chamber Venting? Poly-chloride vinyl? Partly carnivorous vehicle? Peas, chips (fries), vinegar?

PS/ I think I saw on Richard's twitter page that "tires" has a claim to being the original word for a rubber wheel covering. But you're still wrong and guilty of high crimes against language, my friend.

From memory at the time, i think the cap was actually a sight glass so you can see the level inside. Hopefully all will become clear when we eventually get another episode.
