Diff breathers

[Krabby]

From my recollection they are high up at the back in the engine compartment If you take water in through them then your already floating and in deep trouble

Breather lines are already installed?

At the DC event today I asked where they were, and the rep (Tim?) pointed them out on the ramped Grenadier...unfortunately it is not relocated up high into the engine compartment, the front one that he pointed out to us was a simple differential vent located on the driver side portion of the front diff/axle (obviously this could be remedied with a piece of fuel line and zip ties) Regrettably I did not take pictures of this but will do so next week at the NY event.

As Promised, here are some pictures I was able to snag of the diff vents on the ramped Grenadier at the NY event.

-Red Arrow indicates the Front Differential Vent (Driver side biased)
-Green Arrow indicates Rear Differential Vent (Passenger Side Biased)

Nothing Special, as expected, but here they are FWIW

Fantastic. First photo I've seen of them.

I think I recall @Ingemar mentioning, in one of his videos, that his had extended lines? I wonder if that was extra prep by Ineos post production line?

Do you have any idea how those diff breathers work at the full wading depth of 800mm

Working assumption is that they are just one way.

That's how it looks to me- just like the Toyota factory ones. Hopefully they are easily unscrewed and then replaced with a real breather higher up.

How do one way breathers work? surely air should be allowed back in as the diff cools down otherwise you have a vacuum

How do one way breathers work? surely air should be allowed back in as the diff cools down otherwise you have a vacuum

Usually through the axle seals.

OK thanks. I just never understood the process.

Ok from reading that isn’t there a flaw in the Ineos design then,
vacuum created and then drawing water into the axle via the seals whilst wading. I dont suppose wading mode could mitigate that

I'll be running them up into the engine bay/RAI or other. Rather they are out of harms way. Perhaps IA know exactly what they have done and why but until fond out more will plan to re-route.

Thanks for that Dave I understand now. What I don't understand then is what is Ineos thinking? Is it that if you switch on wading mode you will then get a warning telling you to wait for diffs and transmission to cool down before entering the water? They must know something we don’t to say you can confidently wade in 800mm of water with the one way valves installed.

This is the setup Ronny Dahl recommends but he also recommends waiting a minute or so before doing a water crossing

Thanks. I want to get to the bottom of the Ineos thinking on this. The Grenadier is built on purpose after all

I guess they were thinking their solution will be ok for 90% of their customers and the other 10% will change whatever they supply to their favourite solution anyway.
You can change those percentages to whatever you want/think.
Keep in mind they have always said it is a platform for owners to modify and build on.
Price is already high enough

It would be handy if any “owners” could look in the manual to see what Ineos say on the matter and indeed check the diffs. I can’t believe they would leave themselves so open to potential claims regarding damaged diffs etc. They clearly state a wadding depth of 800mm - they have no caveats regarding seals or breathers so presumably they are confident that no damage will occur. Really disappointing if owners have to make mods on a “built for purpose” new car designed specifically for wadding at 800mm.

I think we just need owners to check that the installation seen on what I assume to be prototypes in the US is actually what's on production vehicles.
