Freelander 1 2004 KV6 weird vacuum hose

Trust me I am. Will strip it down as much as I can. I have the usual leaking thermostat housing issue anyway and will be doing the cam belt so I might just do it all in a oner and see how bad it all is.

Have you done the belts on a KV6 before?
If not. Follow my guide in my sig.
Thermostat is easy, providing you are methodical.

I have a friend who owns a garage.... I have also read your guide it was what lead me to the forums in the first place.

OK found another picture of a FL with the same set up on this forum https://translate.google.com/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http://freelander.spybb.ru/viewtopic.php?id=768&edit-text=&act=url

Which has taken me full circle on my thinking about this. I will get the VIN from the engine and trace back to see if it's a NAS or not.

edit:

is the hose that actually fits without me buggering about. This is the one I should have ordered and will tomorrow - it's the NAS.

Britrest on this forum also has the exact same hose setup on his NAS for the vacuum arrangement. https://www.landyzone.co.uk/attachments/hoses-jpg.53351/ from this thread https://www.landyzone.co.uk/land-rover/kv6-timing-mark-not-like-the-book-or-write-up.243276/page-2

Your KV6 is an EU spec engine. So the NAS pipes won't fit at the throttle body. The TBs are different between the EU and NAS KV6.
Yours should be connected as my original picture, with EU spec pipes. Any other connections or pipe routings are wrong. This could well affect brake performance and engine mixture control.

The breather pipe I picture is 100% correct for my throttle body. It plugs into the rubber section before the metal air intake using a 90' white plastic connector. Your intake (the metal part just behind the induction kit where the jubilee clip slack sticks up a little) has a plug to attach the breather hose. On my engine, you can see in the picture, this is solid metal and not a hole.
This is my air intake:



The breather is the black pipe coming down the middle of the picture - you can see the splice I had to put in because the EU pipe didn't fit (I've since sealed this correctly).

Other differences are that I have the pencil style coil-cover/sparkplug covers at the front, the wiring loom for the parks and injectors is different and the brake servo is also different.

This is what is coming from the intake to the brakes/right side vacuum connector

Still happy to admit that it's an EU spec and someone spent a lot of time and money re-doing the pipes and intake incorrectly - is there any way to 100% tell?

Thanks all again for your help.

It appears that your V6 is the later EU spec engine. These weren't very common, so aren't seen often. There were some obviously some changes to the pipes, but they should all still function as intended. The large breather connection into the TB has been moved into the induction pipe. I can't see how the small breather can connect to the brake booster though, as available vacuum will be low. More investigation is needed here.

From the RAVE

"
Vacuum Enhancer System
Vehicles from 2003 model year – The vacuum enhancer solenoid valve is no longer fitted to vehicles from 2003
model year onwards. On these vehicles the solenoid valve is removed, but the venturi valve and associated piping is
retained. On this system the vacuum enhancement is still required, but due to the deletion of the air assist injectors,
the vacuum enhancement can be permanently operated.
The vacuum enhancer system increases the relatively low vacuum available from the inlet manifold to increase
braking assistance. The system consists of a venturi valve, a solenoid valve and associated pipes.
The venturi valve is installed in the vacuum pipe between the brake servo and the inlet manifold. An air feed pipe,
from the intake duct upstream of the throttle body via the solenoid valve, is also connected to the venturi valve. Internal
ducts in the venturi valve connect the brake servo and air feed ports to the inlet manifold port. The duct connecting
the air feed port to the inlet manifold port incorporates the venturi. A check valve, integrated into the brake servo port,
prevents the reverse flow of air and fuel vapour to the brake servo.
The solenoid valve controls the air feed to the venturi valve. Operation of the solenoid valve is controlled by the ECM.
To improve engine idle speed refinement, when the gearbox lever is in Park or Neutral, the solenoid valve is closed
and the brake servo senses the vacuum in the inlet manifold via the venturi valve. When the gearbox lever is selected
to positions other than Park or Neutral, the ECM energises the solenoid valve and air from the upstream side of the
throttle body is fed to the venturi valve. The air flows through the venturi valve into the inlet manifold. As the air flows
through the venturi in the venturi valve, it increases in velocity and decreases in pressure, resulting in an increase in
the vacuum sensed by the brake servo. Depending on ambient conditions and"

OK - £5 via paypal to anyone who can get the cocking part number and where to get this bloody hose/pipe

Can you not find it here?

Cheers

Na - it's not a radiator hose - have scoured that site, only references the pre-2004 version. Useful stuff on there - just not what I'm looking for. The pipes here http://www.allbrit.de/UNI.cfm?PAGE=837712&SPRACHE=EN are the old versions that wont fit. (LLH102980 and LLH102980A are incorrect. Breather hose for my engine is llh500220 with the 90' white elbow joint if that helps)

MOTHER OF GOD..... after 3 days searching... llh500220 looks like a winner!!!!

Ordered it from here... http://www.brit-car.co.uk/product.p...ather_hose_v6_freelander_1___rover_75___mg_zt far in a way the hardest part I've ever had to source for a car. Why the part numbers are not in the rave is beyond me (for that particular part)

FYI as you probably already know, the pipe you linked LLH500220 is the one I have on my NAS V6 Freelander and is the larger diameter pipe. it does not match your picture in post 30.

Here is a picture of my pipes
(I live in Canada)

Hiya - thanks for the response. The correct pipe is http://miamibritish.com/shop/land-rover-crankcase-breather-hose-v6-freelander-llh500130l-oem/ and it's now fitted. Yours looked very cut-and-stuck and certainly doesn't look like an original pipe.

So this may be a stupid question, but I'm at a loss. The red clips that you plug the breather into, what are those called, and does anyone know where I could possibly be able to find the larger breather hose clip? The break servo clip is to small for the larger hose.

hello how are you? please clear your doubts. Can I exchange these pipes for silicone tubes? If so, can you tell me what their internal measurement would be? thank you very much
