What is this part?
Permalink  
 


I noticed a part in the engine bay above the AC pump with a water hose and small filtered air intake, what is this component? I waited to post this question after episode 37 because I though it may covered in there. I know there is a another episode on the Shelsley Walsh Hillclimb event coming up so it could be in that one. The photo was taken from user Krycaro (https://badobsessionmotorsport.activeboard.com/t67833160/spoiler-alert-thread-binky-photos-do-not-enter-if-you-want-t/) and it can also be seen in Rusty Love's video of the event [video=https://youtu.be/D5Q6jtxjN2s?t=3430]

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.

catch can

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.

There is also what looks like a cap, maybe for an oil drain?

I realized you meant that as a joke but the fexi-shaft does not have and provisions for lubrication and beside it is internal line with PTFE for smooth operation. I am trying to figure out what would need a water hose and a small air intake, I should probably ask that on reddit.

Crank case breather, surely?

It is possible, but why vent to atmosphere when you can try it back to the intake manifold like most other PCV systems?

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.

they have fast forwarded a few items in the last few episodes. items like the catch can/breather setup, aw well as the drive by wire pedal setup.

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?

So I have been looking into if t is legal to vent the crankcase into the atmosphere. It seems like it is not legal (https://www.legislation.gov.uk/eudr/1983/351/pdfs/eudr_19830351_adopted_en.pdf, look at section 5.2.1.3.2 on page 7). Although I am not a lawyer and I am not sure if this law is currently in place. It looks the box has a oil catch can and filter biuld into it in order to meet emissions, but why go through all that trouble when you can just tie it back to the intake manifold, maybe with a traditional catch can.

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.

it's probably an air INLET for PCV system . the canister is a baffle to prevent oil discharge on over-pressure in crankcase on de-celleration and cornering. quite common on race engines stateside (colonies) to prevent oil sloshing onto track and tires (tyres)

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.

Partially Consumable Venusian...?   positive crankcase ventilation   and now for something completely different : the gasket sealant RTV   is correctly called ( room temperature vulcanizing)

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.

PCV as in Positive Crankcase Ventilation (steps off nerdy soap box)
