Here is the link to our intake leak test video
• Intake Leak Test - DIY... - ยานยนต์และพาหนะ
The fact that you're thinking of a trail repair possibility being in the middle of Germany gives you top props.
Great troubleshooting skills you two!
The plastic weld is a great temporary fix, with the staples giving structure to the joint. Melting a ziptie over the surface and into the crack before epoxy is added also helped get back from outback NSW. Thanks for the videos, they're terrific.
At last Vera - inlet manifold fix! Thank you both very much for the video 👍
Another great video. I received my patch and sticker this week, thankyou Vera
Thank you Vera and Christian. Your videos, like the Christmas Market, are just MAGIC. With love and best wishes.
Well done once again, keeping LandRovers alive, fixing things with glue and scrap metal.
Couldn’t think of a better description (Grumpy old man, who dislikes LR and EAS)
Thanks for the Australian references!!! I know you get a few mentions on the Aulro forum.
Also seeing a German with a sense of humour is a wonderful thing. Take care and thanks.
Australia is on our bucket list. Hope it will work out one day. Christian
Well I am no on the Simpson trail but we have this issue getting our trailer up Mt Hotham so thank you so much for this tip, you did what I was thinking and provided it can be done
I'm with you Christian - night markets are for the birds. Love that old barn; built in the days when things were done properly (like your fixes).
Cheers from the Simpson!!
The inlet manifold is made from Nylon 66 (glass strand filled for strength), waxy plastics like nylon do not glue, they are ultrasonically welded or with heated inserts in manufacturing (I used to produce these type manifolds for VW, Ford and Jag 👍). You could try welding the crack with some nylon filler rod and a soldering iron… the problem you will have is the crack will be contaminated with oil so won’t be a long lasting fix.
I guess Land Rover omitted the glass strands to save costs....... You can bond Nylon 6/6 and other nylons these days, there are products available to do this.
@@einfelder8262 yes, but bond is the operative word there, you need to fuse the materials. nylon doesn’t like to bond even with a clean and roughened surface, yes it will hold for general use but add vibration, heat, contaminants and pressure and the bond will fail as its only on the surface, where if you fuse by welding its into the material forming a stronger mechanical hold, glues just don’t do this for all the marketing waffle they show. Just for clarity I was a qualified plastic molding technician for years and work both in production and development sides of the business. I have discussed this with both engineers and chemists as well, they are qualified and know their stuff 👍
@@einfelder8262 I could go through how many things Land Rover Ommited but my beer would get warm. Land Rover is a prime example of the accountants beating the engineers.
I thought already that this type of "plastic" is probably not the common HDPE stuff or similar, which can be PE welded quite well.
I assume intakes are the same material? Is that correct?
@@derJackistweg most inlet manifolds are nylon with a glass strand filler to give it more thermal and dimensional stability 👍
Merry Christmas Christian & Vera & thanks for the entertainment 👍
As i mentioned before that i found your channel by accident, i'm not a Land Rover person even though i only live about 5 miles (8km?) from the factory, but your videos i find so interesting & i enjoy the fun & laughs you give me, it brightens up my day ☺, they have a German Christmas market in my city of Birmingham every year, so you've got an energy crisis, i thought it was only us!, @19.26, i've got a very friendly Robin i feed, it even takes food from my hand now
The intake manifold are actually Peugeot, Citroen made, and they are very prone to cracking around 90-100k miles!
Once again very educational and easy to follow.jb weld going into the work shop from today.great video once again👍👍👍i go to those who know, not those who think they know.no landrover dealers.in ireland use hb dennis airside.looking forward to the next video.thanks christian and vera👍👍👍
G'day Christian and Vera, I did a similar repair a couple of years ago using West System G Flex and fibreglass cloth on my 2011 Discovery 4.
Loved the video and love your channel. Merry Christmas Christian and Vera
Always enjoy the videos keep up the great work.
Always enjoy your videos keep up the great work
Again another highly informative video you have just helped me as I am going to be taking my Discovery 4 on the Canning Stock Route, I will now take some epoxy to fix a problem like that
I loved how you keep refering to Australia
Let us know how it went. 😀👍🙏🙋♀️Vera
Great video and always handy to see a bush repair for these faults. JB weld on order for the spares box 👍big surprise to see our names in the credits ❤️merry Christmas
Ingenious!
I hope that the people on those Trail Convoys are sensible enough to download all your content before they set off for the desert...
More great & informative Sunday entertainment - many thanks as always.
PS @Christian - huge sympathy re: being dragged around the Christmas Market - I was just thinking, if I was in that situation, I'd be straight on the gluhwein... and there you were drinking some!
Thanks 🙏 Christian
I am here early, I have a friend who kept getting reduced performance
and he found out what it was he was always running low on fuel and it was that what triggered it he always left it so he had 20 miles range .those smoke detectors are great, thanks for the video
I could so see my youngest daughter and Vera Christmas shopping, they seem to have the same energy on the subject.
Now I know why it's taking so long to get a Ineos Grenadier their engineers only get to watch one of your videos a week and can't figure out how to fix all their problems? Great Christmas Market and have a merry Christmas and stay warm!
Shortly after watching your cider we had ti's fault. I used lb weld on its own but only lasted a few days. Then used the hot staplr gun and jb weld. it's lasted 3 months and still 👍 Great work guys.
Hi
Love the channel
I never owed Land Rover products but have been tempted by theLR 4 Disco.
I now have to purchase a house with a garage complete with a pit !!!
I am going to retire and my wife says I need a hobby sounds like a perfect
Thanks both
Ignore the doubters they don’t have the courage

Another great episode of bush mechanics. Keep it up. My D4 goes in to RP about every 2 months. It's not the manifolds and I can make it go away.
I've been thinking about a bush fix for this problem for a long time. I decided to use glass fibre matt and the usual 2 part resin for glass fibre work. Otherwise, the same as you, but I've not yet done it. It should be much easier than shaping a bit of metal and cutting your bodywork up to get it ;)
Today I tested the temperature experienced by the outside of the inlet manifold, and with an sump oil temperature of 112C, the inlet manifold plastic was 61C.
Grumpy old man, Canning Stock Route 😂 Oh my gosh LOL😂😂😂 Awesome repair and thanks for the nice Christmas tour of your town. ✌🏻
Afternoon Christian & Vera 😊 Another good bush fix lol 😆 Love a German market 🎄 We usually visit Antwerp in December Take care both of you 😘🏴
I was planing on going to the Netherlands on the 17th of December, but now I have to go to Oldenburg instead. Have a great time there. 🙋♀️Vera
A lovely authentic Christmas market. Much better than the commercialised ones we have here in the UK. I agree that it is all Christmas Junk though 😀
I wouldn’t normally comment but just to say I enjoyed your piece about the German Christmas market, and the rest of it of course. I haven’t got a disco but I do enjoy your repartee with each other. Greetings from England, there always seem to be “trouble at mill” with your vehicle.
I reliably fails every week for a new video. Thanks for watching. Christian
Another great video cheers Paul
Ah lovely fix and lovely market. I attended our local Kyneton Village Twilight Christmas market on Saturday with my table olives. Had fun and made some money! I'd sent you my video of it but i don't know how on this forum.
Another great video, thank you both,
i really like your "bonuses" after the video like the Xmas footage in this one 8)
We have been able to now purchase alloy manifolds at a very reasonable price. Slight modification required but so far so good. No more splitting those plastic seams….
Well I wasn't expecting you to do it that way. I'd settled in for the full 12 hour LR Time tear-down! I don't feel cheated, I'm so glad you didn't spend 5 days replacing the inlet manifold like I did. Mine wasn't leaking from the same place as Rainer's so I had to do it the long way but with the body on. It is very hard getting at the bolts at the back of the engine under the body. Anyway, great video and hope Rainer doesn't get the bing bong for that fault again!
😅👍I think Rainer is happy with fixed it. Let's see how long it will last. We would not be able to do such an extensive job on any Discovery except our own, unfortunately. And I am not sure if Rainer, himself, is up for the job. 🙋♀️Vera
Another humorous enjoyable video, perfectined " desert repair "😎
Very beautiful christmas market. Thanks for the video 👏
Great fix this happened to a guy I know must be a common problem and yes cost him £2000 to fix it and thats at a normal garage, great Christmas market in your town and good to see the woodworking room team still put up those poster 😂😂
Wow! Another excellent and amazing video from you guys. You guys are so hilarious. I liked the joke... "for as long as you don't say it in the bedroom...". I was just in stitches. 😂😂😂🤣🤣🤣🤣 Thank you once again for the entertaining and educational video. I can't wait for the next one. 👏🙏🙏🙏
Great show both. In Birmingham uk, we also have the German Market in our town centre. I think a bush fix might be some superglue gel squeezed into the crack
Thanks for the Christmas look, in Germany, where my 3greatgrandparents were from. I like the repair part too and Vera I'm with you, shorts as often as possible!
😅👍🙋♀️Vera
Another great science project
So interesting to watch
Hands off Andrew!!! 😁
Nice fix. So glad I have the Ford 4.0 V6 gas engine. It may be underpowered, but it's nowhere near as complicated as the diesels. I replaced the spark plugs when I first got the LR3, just under 8 years ago now, and the only other thing was the pulley idler bearing and the accessory belt.
Yes, the petrol engines are more reliable. Christian
Excellent video very helpful.
Interesting video!! I saw another video recently where a LR owner repaired the inlet manifold with just Epoxy… yours seems to be a better way of doing it!!
Wish you were nearer… I would “drop by” like Rainer to have a coffee and you could repair my LRs while I just happen to be there!! 😊
Epoxy allone will not do it. There is a lot of stress on this. Christian
I love watching your vids very entertaining informative and inspiring thank you. Oh for a lift that would be amazing or even a garage
JB WaterWeld has a set time of 15-25 minutes and sets hard in one hour. WaterWeld cures to an off-white color, is rated at a tensile strength of 900 PSI and will withstand temperatures up to 300ºF.
Great for your spares box and works under water!
I am going to order it. 👍🙋♀️Vera
But a really interesting video from the V&C video company 🤩 Have a great Christmas time with friends and family!
👍💪You too Dave🙋♀️Vera
Hey! Great video guys, I love the trail fixes, something your regular Toyota driver misses out on, when you buy a LR you get all these extra little surprises for nothing.....Another reason apart from the intake manifolds leaking that gives the "Reduced Performance" is simply the diesel filter, I had it on mine 🙄. I liked your visit to your xmas market tho I'm with Christian on this one!! Take care
Yes, you absoltuley have to service and change the diesel filters. That is part of the maintenance one must to do. 👍🙋♀️Vera
I forgot to mention that another problem with the fuel filter is that the sensor inside it gets stuck, indicating the reduced performance. Also, the water expansion tank has a similar sticky sensor indicating low water level 🙄
@@kviasen7603 Hi Finn, sorry, it's the floater that I meant!
Love this especially the Simpson Desert refs, LOL and clever 🙌
Wonderful video
I enjoy your movie a lot . You guys really need to own a land cruiser. lol thanks
Brilliant - Love the Aussie simpson desert references.
Very good video clip for both of you again!
I do not have any message but I found diesel consumption costed more 2 litres for 100 km on highway and oil leak very much if I used more turbo and very soft whistle when accelerating. Dealer diagnosed and charge me for AUS $9500 to replace both.
Mine is very fine crack and it is on the right intake manifold. I approached with different ways: I use SIKAFLEX 252 (withstand heat up to >400 C), L steel 0.5 mm and stainless steel screws 4 and 5mm for metal sheet. After removing 4 pipes of diesel from rail and injectors, I was able to pull the heat shield away from manifold to do the next repair.
Clean manifold and metal with decrease. I screwed 4 holes 3 mm diameter. Apply flat steel sheet with 4 holes 5 mm along and above the crack: glue the flat metal with 4 holes on the manifold and 4 mm screws in. Leave for 24 hours then remove them out. Use heat to weld the crack with heat-up-to-red metal. Apply Sikaflex on the crack with thicker layer and drop a metal sheet 6 mm right on the crack. Leave for 24 hours for curing. Next I used the L metal cut to shape as Christian showed in the video but I applied Sikaflex on top of two pieces of metals and the screw 4 screws 5 mm in after drop some Sikaflex in each holes. I crewed 3 more holes on the dropped sides and put Sikaflex on before tighten 3 crews.
Driving test for under 80 km/h for 40 km distance, I found nothing happened but next day I tested with 110 km/h there was a message @RESTRICTED PERFORMANCE@. Put back the top shield on manifold and the top engine cover, the message disappeared.
HOWEVER, the crack started on different spot after a week of driving - the plastic getting old now - only 12 years. I had a new manifold part and I decide to apply my repair for the whole length of folding on manifold. This is the weakest link. LR should design with two pieces: top part and bottom part separately or they should have a thicker angle or a joint right there or made of alloy...
I will post my idea when next crack happen. I guess in next 12 years!
Good job. Hope it lasts. Christian
I used JB weld to re fit the magnets inside a Bosch drill which had broken away. It's been perfect ever since.... 👍
Unbelievable that stuff. Christian
OK Christian - why do have a ready supply of baby oil in your workshop? You do not have to answer this question. Another great video - thanks.
The baby oil is to re-moisturise Toyota driver's finger tips in the unlikely event that they should need to touch a real tool.
Clearly the fun doesn't just happen in the bedroom..........
Oh my god guys. This is what I was going to message you about. I have a cracked inlet, but I've been spending ages swapping my turbo because the diagnostic tool told me it went into limp mode due to the turbo valve sticking open. Please tell everyone that you can't trust the error codes completely. I spent weeks swapping my turbo when it wasn't the problem because of this. Yes the ECU thinks the turbo valve is stuck open because of the pressure imbalance. But it didn't know I had a crack in my inlet manifold... Thank you so much for sharing this video. I am now in the process of swapping my inlet manifold completely. (Yes I know its a big job, but I want it fixed for good.) As always your insight and advice is brilliant. ♥
swamp your turbocharger actuator arm with 2 stroke oil mixed with kero, and use a long wanded garden sprayer, it fixed my sticking arm after LR said TURBO was KAPUT
@@stuarth43 No I think you misunderstand me. My point is that the Error Codes I got from the ECU were wrong. I got an error code saying my actuator is sticking, but in fact it's not. The ECU "thinks" that's the problem because of the airflow imbalance. But that actually wasn't the problem in my case, it was a cracked inlet manifold. It caused me to swap my whole turbo (including the actuator) for no reason.
Having the same issue, I think. The error codes also pointing to turbo valve open. I'm so glad I came across this video as an option. Mine doesnt go in to limp mode, just the restricted performance error but no power loss. Usually happens around 4000RPM when I'm overtaking someone
Thank you.
Great its lr time👍👍👍
We have come from England to Baden Baden to the Christmas Market this weekend, but we didn’t see you!
Love it....
Merci beaucoup
This is a common problem on the same V6 engines in Jaguars with those plastic manifolds. Never buy the pattern parts ... and replace in pairs as the other will also fail soon and need a 2nd big strip down. They also blow the plastic end of the intercooler apart and as ever .. EGRs fail. If it won't rev above 2,800rpm - then the usual fault is the 2nd turbo actuator failed (few rev that high much, so it gets less use and seizes). Talking of old buildings .. my last home was a former Hall House used as a community gathering place to hold "Courts Leet" - which became our Magistrate Courts and had a Freehold title of 1214 AD - it had been rental from the church before that. There were 2 inglenook fireplaces ... I got visting American friends to put their hand on the big timber Bessemer mantle beam over it and told them that had been there with an open fire burning on the hearth 200 years before the Pilgrims set sail in the Mayflower 😆
Impressive story, thanks. Christian
Given this is such a common issue, maybe the patch would be a good idea as a prevention. I wonder how popular some nice laser cut and pressed covers as a kit would be.
Bonjour, il sera peut-être intéressant d'effectuer prevetivement ce renforcement sur toute la longueur avec une dépose du couvre-culasse
Merci pour vos vidéo
Good job
Only if you have to take of the valve cover anyways. For example during an engine rebuild. And then, we would rather put in new OEM valve covers. A trailrepair like that, or any other form of this repair, will not last longterm. This valve cover has been replaced ever since also. You may underestimate the work it takes to remove a valve cover. That is many hours, and the likely hood that damage something while doing so is high. Only experienced mechanics attempt that. 👍🙋♀️
You probably know, but the water in fuel sensor could trigger the reduced performance warning, not entirely uncommon. My sensor had a error code:-)
Thumbs up.
Thanks.🎄🎆🎇✨🎈🎁
We'd really like to see the LRT manifold swap though !
When I am reborn in my next life as a Toyota driver... Christian
Merry Christmas to you both, Gaffer tape will work to get out the desert
and WD40.
We’ll get some 💪 thanks. Christian
Greetings from Berlin,
I had the similar issue on highway without any error code or restricted performance warning. I just found out that, oil is spilled around throttle body, especially close to the radiator hose. Hope it will be fixed with similar approach :)
Hi guys, when you refer to another previous video do ye ever put the link in the description? Would make it way easier to find the related video. You guys have a lot of content 😀
It’s in the video at 2:00 Min and in the description 🤔Christian
This looks like a great fix even if only temporary! Word of warning if and when you go about replacing the cam covers on either of the Mall crawlers if your using genuine cam covers they are not covered by parts warranty unless all fuel lines, injector seals etc are also replaced…..!🤬 This ends up bringing the parts bill to replace one cover up over 1000€ plus tax (at least here in Ireland). It’s probably handier to just go with aftermarket covers !
@@Vera_and_Christian thanks Christian. Nobody has time to rewatch a video with a broken D3 with a HDC fault out of nowhere but I totally missed the link in the description. Didn’t see it in the iPad app
Thanks again. Hopefully I can get to the bottom of this weeks issue 😓
Thanks
🤗🙏🙋♀️
Thank you for teaching so many valuable lessons. Most valuable out of all - don't bui a land rover car :)))))))
Poster for your shop , 19:56 have to be quick to spot it ....on the left wall.
Not sure if it's Vera approved ☺️
Hello Christian, I love ur videos, I love your humorous coversations in the videos, and I admire ur DIY ability, unfortunately, my LR4 has same problems with Reiner's, same leaking location, I think this is a common problems for LR4 SDV3.0. I am plan following the instruction of this video, in the end of video u mention about yoh will use JB weld epoxy adhesive next time.is it the better solutions?❤
This was just a trailrepair, not a longterm solution. It will break again. We never did use JBWeld, but what you use for your trailfix, it has to harden completely rigid, not soft. Best fix the problem right away with OEM valve cover. It is a lot of work taking the valve cover off, you might as well fix it immediately before you have to take it off again. Especially if you do know that one is cracked. 👍🙋♀️
Christian would make coffee in a Grenadier video! 🤣
Oh no, never. Appearantly you don't know us very well. 😅👍🙋♀️Vera
I wait for you in Uis, Namibia to help you with this fix.
Interesting video. How you keep the engine bay so clean ?
Love your videos as usual
Just an Idea could you not do this repair with sand paper, rubbing alcohol and JB Weld?
Save the Fender
Yes and a beer can. It would work. Christian
I admire your passion for fixing land rovers. I eventually lost my passion and bought a Toyota.
Wow... How long is the list of know points of failure for the D3 and D4...?? 😅
Nice job!
I too share Christian's enthusiasm for all things Christmas . I think we could be good friends LOL
Is there ever a time when Vera is NOT smiling ???? I have yet to see it .
Seeing Vera's smile just makes me smile it's very infectious . If more people were like Vera the world would be a much nicer place .
P.S. With all the "bedroom" talk in the last few videos (One or two at least) this channel is going to end up with an "R" or "XXX" rating LOL
There are many many things you can say in the garage but not in the bedroom .
I can't get it back in the hole .
I think I put it in the wrong hole.
It's just not tight enough .
Make sure you lube it up well .
Etc etc .
Keep up the great video's . You guys make me laugh so much .
Some of the video's are even useful . LOL . Just joking .
Have a good Christmas . But an extra special VERY Merry Christmas to Christian . LOL

Many high quality plastics are infused with glassfiber thus needing more heat to melt.
Don't know how hot that wavy thing gets (I want one though, would be perfect for my Enduro bikes).
It would be cool to meet you in the alps someday. I'm usually there in August each year but I must warn you, I drive a Toyota 😁
A Toyota driver that almost bought a disco2 td5 10 years ago so I might be accepted.
EDIT; jb weld "original cold weld" stands for 315c, don't know if it's the same product you mentioned.
I think it gets around 110°. Yes, the plastic has fiber in it. Thanks for watching our videos and see you in the alps. Christian
It looks like my first post (with a link in it) went straight to your junk folder. I hope you still manage to see it, I've never seen so many land rovers in one place.
I am sorry, there is nothing in the spam folder. Maybe you can send it again. 👍🙋♀️Vera

There is no audio at the start, so skip forward 3 minutes.
Imagine all those vehicles that could be repaired and given new life!
@@RawTopShot Well, we know how tough it is to fix a Land Rover, or any vehicle. Right now, here in Germany, a replacement engine for a TDV6 costs more than a Land Rover Discovery 3 with 200000km. And few are able to refurbish an engine, like we did. So any Disco 3 with a failed engine will most likely end up as a donor vehicle, sold in parts, and not fixed. But I wish we would have access to a graveyard like this. Nothing like this exists in our close proximity. 👍🙋♀️
I don’t think that I’d be brave enough to try that fix on the Canning Stock Route! We live near a town in Gippsland Victoria Australia called Korumburra. Look it up some time, I think you’ll like it.
I think a LR4 convoy would need a few Toyotas on that route. Christian
I'm glad 6th love the Christmas crap like me Christian lol
Years ago I had a (real) Toyota Land Cruiser (vintage J40 1960) which started misfiring when it got hot. Tightened the intake manifold bolts which cured the problem.
Plastic intake manifold?
Do you have "disco lights" to go with your smoke generator?
Bonjour Christian pourrais-tu nous faire une vidéo sur les bougies de prechauffage avec une viseuse à choc ks tools et est ce que les lubrifiant cryogene moins 50 degrés marche
Super Glue.
Thanks for another entertaining video. I presume the fault code indicated P2279 “Intake Air Leak”?
It can show up with all kind of different faults. Bypass valve, MAF, MAP, Boos pressure and so on. I even had it in the sdisplay with no fault recorded before. Christian
genau mein Humor 🙂
Car manufactory BMW Audi seem to use a lot of plastic in places where it should be alloy covers and to replace some parts on new cars means removing lots of stuff to get to the part that needs to be replaced and plastic does get brittle with heat so easy to break parts on dismantling
Yes and there is no improvement in sight. Christian
Is there a thing as a step by step guide to changing the inlet manifolds ?
Just getting back to a vechile snorkel isnt the main ( only ) reaon for the invetion purely to water wade in extreme depth ??
Hey Christian, need an update how your glue held up. Last week both manifolds cracked on our 2012 RRS. Tried to do a quick fix with JB plastic weld 1 hr cure, ha ha. Waited 2 hrs blew one patch within 10 min with caravan hooked on the back. Anyway not quite Simpson Desert but we were in the Vic high country and cleaned up both sides again and tried with JB Steel weld and waited 24 hrs. Towed the van back 2 hrs and now been a week without leak. Bit the bullet and booked in for 2 replacement manifolds, Al billet water valve under the throttle body, high pressure fuel pump belt and hopefully delete EGR.
It lasted until the first really hot days here. About 3 months. It was just a trailrepair with the means we had at hand on the evening it happened. He had to replace it with a OEM valve cover. Right before a big overlanding trip it tore again. And that we recommend, fix it like we did, until you can get replaced by a OEM part. Don't go cheap on the replacement cover, I have only heard horror stories from aftermarket . 👍🙋♀️Vera
