There are only 4 inlet ports, then there are 4 exhaust ports.

Inlet ports at bottom of picture, nice n clean.

Exhaust at top of picture, dirty.

There are 8 inlet ports. The 4 lower ports are the primary ports and the 4 upper ports are the swirl ports. The swirl ports are tangential to the primary ports which aids fuel mixing.
Interestingly the swirl ports do clog more than the primary ports. Presumably because of lower port velocity.

Oops, thanks for that Nodge.

Apologies!

Just reading through as will be doing this to mine soon I think.

Just been out in mine again and I can hear what sounds like the turbo spinning up, now I can't remember hearing that before, is it possible that removing the guts of the egr (thereby allowing a lot more airflow) it is allowing the turbo to spool up quicker???

I noticed this immediately I fitted the delete kit. I came to the conclusion that I was hearing something that was always there but deadened by the bulk of the EGR valve.

Odd, after having fitted the EGR bypass over a year ago the duck noise has just started on mine, though cant say it's an issue only there for a few seconds then goes after engine shut down

EGR cleaned and ready


Manifold ready with new seals


MAP sensor ready


I will also be adding brass unions to my fuel line instead of the flimsy plastic ones



Something I always do on a diesel I did this on my R75

Sorry,new to the forum and quoted by accident.
What I meant to say was that this is a great thread that is full of ideas and help that newbies really need. I have so many things to do to my newly acquired 2001 TD4 in the new year. Thanks to all who have posted.
I would recommend to all newbies to read through as much of any relevant thread before asking questions.

Not sure if it's been mentioned or not but does this mod put the engine management light on or go in to limp as a few other vehicles suffer this when blanking it thanks in advance

I have never known it to, on FL1 or R40 so safe to go ahead

I had that noise too, It was the EGR controller which as it's no longer needed I just removed. It only started for me after I replaced the ropey vac hoses that go to the controller, one of them was worn through so it must have been bleeding any vacuum away. I just blanked off the hoses that were going to it.

I've just fitted an EGR mod valve and the difference is quite staggering! It starts easier, runs smoother, is missing a lag when trying to accelerate from a STOP, feels smoother and is much more responsive to my foot on the accelerator pedal. All-in-all, if you do not fit this mod you are doing your car a great disatisfaction. Fuel consumption figures are yet to be ascertained, but my feeling is this will be better for me, the car & my wallet.

You sure you didn't fix something else while fitting it? I modded 2 cars and didn't really feel much difference. If your inlet manifold was very clogged then cleaning it might be what caused the improvement. Or maybe changing a dodgy vac hose.

Okay, I have studied chemistry, physics and most other sciences. I'm also a confirmed Petrol-Head - since my 14th birthday. By recycling exhaust gasses you are feeding a toxic & noxious mix of gasses and unburnt hydrocarbons into each of the cyclinders. This level of polutants and oxygen deficient gas will inhibit the burn capacity of your engine, thus reducing its power output as well as clogging up the working parts. As the fuel is injected into the cyclinder it requires oxygen to be present, to ensure a clean burn with the maximum amount of fuel disposed-of. The exhaust sould be cleaner and the amount of fuel used should be lesser. Use a less amount of oxygen and the output is, less power, greater fuel consumption, great toxic & noxious gasses from the exhaust and more harmful to the planet's atmosphere and its inhabitants. My car is running better, as I expected it to do. Let me put it another way... If you were to eat **** your body would feel like ****. lol Breath fresh air and live a healthy life. Here endeth my story. BSc.

Not sure it's quite as simple as that, do some research on the topic and you'll find many folk on both sides of the argument. I'd like to think your right but the two cars I modified didn't feel much different. I did it to stop the inlet manifold from clogging up.

Hmmm, then there is also a chance there are other factors at work here - where perhaps worn piston-rings would reduce the compression, which in-turn could mean less fuel being burned as well as output gasses full of oil & abrasive carbon.
If an engine is not upto a good running standard then anything done to help is drastically reduced in its action. My engine appears to be in prestine condition, where regular oil-changes & maintenance has proved to be positive. It came from Germany, put onto Spanish plates. It was serviced by the Gerrys and by all acounts they did a marvelous job.
Which is perhaps why my mod has been so successful? I can honestly say, my 2006 Td4's performance and feel has been given a boost by what I did to the EGR. I'm constantly monitoring my car as I drive it, always. I listen for noises, unusual sounds, vibrations, etc, and if anything occurs that is different I'm ripping into the system to find out why. I used to restore & enjoy old British motorcycles, to the point where I'm sure I've got oil in my blood. I love my car and enjoy looking after it. And I know how to keep it running.

I will add this. I have also bled my clutch today, aided by my wife who is quite adept at pressing the clutch pedal. That job was a real sod to do, as most of you are probably aware. There are lots of other jobs I'm about to do too. Replacing each & every filter, fitting a Crankcase Breather Mod, and lots more. As much as I enjoy driving my Freelander Mk1, 2006, Td4, 3-door, car, I am only ever happy when I know the car has been fully serviced... by myself. It's so easy for any garage to turn around and state the car has been serviced according to the schedule, as dictated by its year & milage, but it's also so easy to say one thing while not doing what is said - and charged for! As a retired aircraft engineer (multi-skilled), I can only be satisfied by knowing for certain any specific job has been done - to my professional satisfaction. And seeing is believing. Also, what oil is being poured into your car if you allow another to 'service' it?
Call me sceptical, or whatever, but when I drive my car I want it to be reliable, efficient, fully-functionable and beautiful. A bit like my wife, I suppose. lol
But what i am trying to say is this, look after your car. Service it as if it is a part of you. And enjoy the rewards of driving something that should not let you down.
When did you last check your oil level, tyre pressures, etc? Look after you car and hopefully it will not let you down.
My Glow-Plug system is about to revamped. The standard Land Rover Hi-Fi (which is very good but lacks certain features) is about to be replaced. I have forward & rear cameras installed. And more when I think of it.
I love my Freelander.

Anything more we're all doing wrong?

Wot you grumping about Grumpy. He's just talking about wot most of us are doing anyway.

And he loves his Freelander thus proving he's a nutter.


Just like the rest of us,

are u trying to say we service out landies to an inch of their lives,

surely not
