Mate, I would be a LOT more worried about other stuff if the cars in that deep!!! :D And I have said it before, A "snorkel" is NOT an excuse to drown a good car! Its primary function is dust reduction and filter life extender, with a bit of protection against a "whoops!! Who put that bloody waterhole there?!!
It's exactly those "whoops" moments that I'm looking out for! :D Best to know that the kit is serviceable and won't be part of the problem push comes to shove.Quote:

2) as said above if water was to get to the manifold would it get in through the outlets on the top
3) the 4 breather model has Front Rear ,transmission and fuel tank ....what is the function of the breather on the fuel tank .......and is this the same purpose to raise it up .....also how resistant to water ingress is the outlet
Diesel engine, hot diesel in the tank, cold river... and science.Quote:

Maybe it's an extreme outcome, but same principles apply.
Ok thanks so it prevents a vacuum forming in the tanks and sucking in waterQuote:

They're "breathers", so they're not "water proof".
Having said that, if you watch the video and how quick it all works, by the time those breathers go under water, everything will be cool enough that they won't suck up water. The breathers themselves if they do go under water will let very little water through anyway. And I would think if your that deep in water, you may have more to worry about then the diffs etc.
Thanks for that .....makes sense ...Quote:

My understanding is that having an operations diff breather above the potential water line means that the pressure difference will be equalised through this point of least resistance, ie not thru diff seals, hubs etc. If you were to block off the breather ports on the manifold kit, then you'd be defeating the purpose of the whole kit.Quote:

Fitted the 4 breather unit to a Defender TDCi (puma) 2.4lt
*The 2.2lt has the three breathers (diffs, transfer case) up as noted in the engine bay.
*The early 2.4lt has the rear diff breather only up vertical to the body at the rear, so the kit will be short some of the thin tube.
*If you have a 4 breather kit, there is plenty of the larger plastic hose left over to run enough to feed the rear diff to the front. The larger plastic hose will slide over the thinner tube, but is a nice tight fit and will need a bit of say silicone spray lube to join together. At the other end, do the same, slide in a small length of thin tube.

IMHO.... being blunt and honest when it comes to fitting accessories as so many "accessory suppliers' seem not to have actually fitted their oh so good life saving kit to a vehicle...
The Nugget Stuff breather kit:
Pros.
*Neat nicely finished. (not a hodge bodge of stuff from Bunnings).
*Quicker to fit than running off to Bunnings.
*Serves an actual purpose and not just a BS product.
*Will see the life of the vehicle out.
Cons.
*Not as cheap as buying bits n pieces from Bunnings, but see above.
*Would be really good to see some form of plastic cover that clipped over the breather mount. This would still allow the breathers to do their job but would protect it all when pressure washing down the engine bay and also greatly reduce ingress of mud, dirt, water.
So to me, I'm not even going to bother prating around with any other option, buy the kit and install it.
hope the info is helpful.

P.S forgot the oh so important pic
Yep, just installing it now.
Mine was one of those with the breathers just up near the floor, not up on the firewall. Have ordered some extra 6mm tubing from Nugget because I can say from experience you can't buy the same tubing from either Bunnings or Autobarn.
Why fit it? I don't want water in my diffs or fuel. Easy choice for me. The cost of the kit would be less than even one mechanical problem caused by not having breathers.
Incidentally, I discovered the Long Ranger tank fitted by the previous owner included a breather up to the filler, so I'm all good.
