Disco 4 (LR4) Breather pipe heights ??

Hi Everyone.

Can anybody tell me where the various breather pipes, axles, etc etc terminate on a straight from the factory 2013 D4 3ltr tdv6.
Heading up in the Dales over Christmas and the main road A1 to Hawes is prone to flooding with heavy rain.
As the wading depth is given as 700mm can I assume they are extended to that height of higher ? have never had to "wade" and hopefully won't have to, would just like reassurance, or is extending a good idea.
Thanks in advance.
Mick

We'll be up near there at Christmas, as usual! The road to Hawes and others can well be prone to flooding but we've never really had a problem.

We get off the A1 on the A59 to Knaresborough, pass through it then onto B6165, followed by High Moor Lane to Brearton and have a lunch at the Malt Shovel, then carry on Brearton Lane to join the A61, turn right onto it, go around Ripon, and then to Masham, near which we will be staying, but you could carry on via Middleham, Leyburn, etc to Hawes.

We have done this in our 300tdi and our TD5 so a load older than yours. They don't wade as deep as an LR4 and they need wading plugs. I know little about yours but I do know that if you read the Manual you'll find all you need to know. But the breather pipes will extend far enough up to cover the official wading depth and probably more. And don't forget to raise the height to the max. As a rule of thumb, if the water is becoming higher than the hub on your wheel you might want to think about backing out and finding another route. We once had to try 6 different ways out of Hawes!

The official guide to wading always suggest you put your waders on and walk in front of the vehicle with a stick which will be used to prod the surface in front of you to see if it is still there and what height the water is up to! Can't see you doing this in your Christmas hols! But then you might enjoy this!

We stayed in Leyburn for years over the Christmas week until the owners started letting the places longterm. Love the area and have been going since about 1992.

Have fun!

Good Morning and thanks for you reply & the interesting Rover Guide.
We've been to Hawes a few times now and normally take the A1 to the A684 and straight into Hawes (coming from E coast). The 684 has a few spots with serious flooding potential; our friends had to wade a bit when they left earlier than us after floods in November a year or two back, in an old motor home, (ex Fire Brigade) so he is cautious & sensible. I wasn't sure about breathers on the axles and to be honest I should have gone straight to the manual, but they do lack detail with certain things and I tend to look for "How to videos" some of which are very good. I was surprised to see (on the news recently) a Discovery sitting in water axle deep and being passed by an older defender which made me wonder a bit ref how well they prepared for water when they leave the factory............"breather extensions ?? Oh! they're additional" perhaps.
One of the benefits of retirement you can always stay put if they have room, we tow a large twin axle caravan so no intention of taking that through any water.

The diff breathers are well above 700mm, the front one is visible in the engine bay. The rear diff breather is routed inside the vehicle, behind the boot trim, along with the air suspension compressor air intake.

It's sensible not to put the vehicle through water as deep as LR say is maximum wading depth, as oil seals loose sealing ability over time, so you could find wheel bearings failing shortly after a deep wade. Also if there's mud and lumps of debris in the water, it can easily get trapped under the timing belt cover, with potential belt failure as a result.

Thanks very much for that, its good to know that protection is built in, and of course good sense is a must, see to many clowns going like fools with a bow wave like a destroyer, and the bit about hidden debris is also a good reminder.
Thanks again for your reply, as always good advice freely given on a great forum site,

That puts a completely different complexion on things! Don't know if there are any threads on "How deep can I go when towing my caravan"!

The route you take, which is the most obvious one, if you know on it the places where flooding takes place, you might be able to avoid it by detouring round, without having to go too far out of your way. My route is possible, some of the streets are a bit narrow but still doable, but you probably don't want to stray too far from the route you know.

As for Defenders passing Discoveries, the water around and under the Discovery may have been deeper before the Defender went past it! Or else the owner may have chickened out and just left it there. There are lots of possible reasons for that sort of sight.

We saw a Defender "parked" in a hedge next to the main Ringwood-Salisbury road last night. At a near vertical angle. No idea how it didn't topple over, no apparent reason for it being there, no police, no ambulance, no recovery, no tape around it, nothing! Would love to know the backstory on that!

Anyway, you've probably got enough advice to be going on with so I'll shut up now but pm me if you think I could help, although people who live near your route all year round may be more useful!

Cheers! Stan.
