It’s a shame that only a few people have the patience to properly work on a vehicle of this complexity. Good for those that do. Great video.🏴󠁧󠁢󠁳󠁣󠁴󠁿🏴󠁧󠁢󠁳󠁣󠁴󠁿

I don’t have a LR but it’s too wonderful to watch Vera and Christian in action !

This is why a Land Rover (or any manufacturer) service history needs to be doubled checked. Great work as always - well done Christian and Vera.

I think it was the Gromit attached to the Floppertatter valve behind the giggling pin !! Great content as always guys. ❤

Fantastic video as always. I own a LR4 2013 and I am getting very nervous about the potential for things to go wrong. It is a ridiculously complex machine but you both seem to tackle any repair job with such a calm and confident manner I wish you lived around the corner from me in Australia. Keep up the great work.

I can see the people at Land Rover seeing your videos and thinking we should pay these people to not make videos about our cars as he must be putting lots of customers off buying our cars he is showing up our dealers who are not so good at fixing our cars I love you guy so entertaining and informative.

My guess is the bottom bolt penetrated into the transfer box casing so you took the bolt out and put some sealant on a shorter bolt. All caused by the bolts being a different length.

This is the best yt channel, you guys produce the best and most useful content on all of youtube! I recently became the owner of an LR Disco 4 and this channel has helped me a lot to understand the complexities of the vehicle as well as the potential problems that an owner can face. Keep up the great work! Greetings from Serbia. :)

I admire your confidence Christian in tackling theses problems, great video, educational and entertaining.

My guess is the lack of Toyota parts are causing it to leak. Great videos are always ❤️

Great video - super realistic in that it shows that not ALL 'repairs' actually work (because sometimes the issue is not what you originally thought it was). Looking forward to the 'great reveal' in the next week or so.

A really Great episode today guys! That was some work, and must have been very frustrating to you both after all that. I've no idea whatsoever as to the source of the leak, so I look forward with baited breath until next Sunday!

Some days you get the bear and some days the bear gets you!🙂 I greatly admire your skills here and that you have the humility to admit when you get stuff wrong. As someone not very mechanically inclined when young (or now), and motivated then by a low income not to get stuff done by garages, I had little choice but to do the simpler stuff myself. So many of my repairs on the wrecks I owned were done with an oily Haynes manual in one hand and a collection of things that might vaguely be described as tools in the other... Lots of swearing, skinned knuckles, ruined clothing and second or third attempts to get stuff working.

Excellent video as usual. Of course LR4 is my favourite topic along with LR Time. I found it easier to remove the exhaust and DPF complete rather than to try and disassembly those 3 rusty bolts on the rear DPF flange. Of course had to grind them off! Once the DPF is ready off, great idea to check the actual soot covering to see that your regen is really happening. Looking forward to the sequel today.

I have no idea what caused this oil leak, as I own a Toyota and do not have oil leak problems. The medical specialist say, “ if you use your brain to its maximum capabilities, it’s unlikely you will suffer with dementia”. I can positively say your going to be ok due to the usage of your brain. However as a Toyota owner I have no need to push my brain capabilities on Toyota repairs, I’m more likely to suffer with that brain memory disease, what ever it was called. Love you guys ❤.

I'm guessing at either it's the porous box itself or the electrical plug O ring? Anyway, another great video from the both of you 👌. You really do have a lot of equipment now to make your repairs a lot easier! I really like Vera's OMG's still, what would a video be like without them 😁. Take care you two

My try on the oil fault....... The bolt had broken though the inner casing of the TC, leaving a small crack on the bolt seat. As the bolt is at the lowest part of the TC it "sweated" out slowly. I am most probably wrong, I just like you guys so much that I had to take a swing at it. Thank you again for wonderful videos! Best wishes from Pretoria, South Africa

Another great video, so in depth, hats off to you both for all your hard work

Christian and of course Vera I recently had a steel sump installed on my transmission (Australia) with the vehicle being 12 years old and having travelled 140 thousand kilometres. Apparently its the thing to do in Oz ! Great video keep up the good work. Auf wideseihn.

I also own a LR3. I live in French Lake, Canada. Your videos are great and I enjoy them very much, thanks.

What a tease. I have no idea but I think it was something silly. Good entertainment again. Great job by Robin too.

Oil from above, turbo feed line possibly, love the content you work so well together, I would have been more upset than you seem to have been after removing the transfer case and then finding the fault still exists!!

Nice to see new videos from you guys ✌️. Please do not blame "Land Rover" for bad repairs. The guys from the dealers are unexperienced, they just don't think and it is not just the JLR dealers... For an 8HP70 oil leak concern from the back of the automatic transmission, the root cause of the leak, can also be a porosity issue with the case. I am happy to support ;)

Your son, Robin, is VERY helpful!

Another Brilliant video really appreciate the dedication you both have!

A brilliant video of the repair (although the final solution is yet to come). I have no idea what caused the leak but I'm here to learn 🙂 Have a great weekend folks.

Christian and Vera always look forward to seeing your video blogs and great entertainment…: ❤🇬🇧

Amazing work… You are now an Official LR Guru Deutschland Magician! 👍🇬🇧🤣🤣

You 2 are fantastic great sence of humour and what skill & knowledge you have

You and the wifey make a great team together! In my opinion, that has to be the most valuable thing a couple can find in eachother! 😊

Great video for a Sunday. I believe your leak is coming from a pin hole in one of the case pockets to the right of the transmission output shaft. I believe ZF had a recall for this. Cheers have a great week!

As always, I absolutely love your blogs!

Good evening. Vera Christian & Robin. What an absolutely fantastic video even though I don’t have a clue on what causes that oil leak 🤪 I can’t wait until next Sunday already I’m so excited 🤩 And of course a kiss for Vera 😘 xx

Another fun episode, good thing you have a land rover addiction, never run out of leaks and drips!! My thought for the leak is the trans cooler o-ring(s) at the trans-case! looking forward to my awesome lr time t-shirt🤠🤠 Thanks again for the great lr times ~ Roger

Land Rover, is definitely a kind of car, that will make a owner/gearhead very happy. Plenty of things to do, and is really satisfying to fix it, and see everything woking properly.

Ooooh - A cliffhanger. Great stuff from Christian & Vera as always.

Hi, another glorious video. I’m always looking for Sunday afternoon to watch it. My tip is :issue on ventilation of the distribution box🤔 Martin

Blimey, filler cap or breather vent not connected - something really simple! I hate teasers like this, I want to know!! OMG. You two make great videos!

I owned a D2. I was delighted at how comfortable and versatile it was. I always wished for a D3. After seeing you need a full workshop including hoist, custom manufactured tools, and seemingly limitless time to maintain these later models, maybe I better avoid. When I worked for the Royal Flying Doctor Service out in Central Australia I replaced the D2 with a Defender with the BMW designed TD5 because of the harsh conditions (no roads, severe dust). Despite all the local Toyota pundits braying like donkeys about my Defender it performed flawlessly and only needed oil/filter changes. I did however have to spend much time underneath initially filling all the holes in the body with silicon sealant. The body construction is very crude but very practical. If you actually need a 4WD the Defender has many attention to detail which make it a workhorse eg. metal guards over exposed fuel filter which D2 does not etc. I enjoy the good humored camaraderie between you two. Amazed at your patience. Thank you & greetings from Brisbane Australia 👍🏻 🦘

Maybe the 10 bolt inspection plate?……..another excellent job assembled better than it was so well worth while…impressive!

Good video👍 My wild guess will be that the leak is coming from the mechatronic sleeve connector housing, it's got an o-ring. But i don't know if it's prone to leakage? Ps. in some of the underbody videos, you may need some better lighting. It's a bit difficult to see where you're at some times.

“Oh my god” I have to wait another week to find out the problem. At least you are one step closer to my vehicle with the 8 speed auto, your videos are great but you need to get a 2012 L322 so we sing from the same hymn sheet. Great content keep it up. Have a great xmas all the best Neil.

I'm guessing a simple turn to lock in the wiring sleeve for the mechatronic unit. I've done this repair on my LR3 and sympathize with you! Great video ✌🏻

Great video, problem is porosity in the automatic transmission shame main dealer didn’t check for bulletins

My guess is the leak is at the seal for the electrical connector, specifically the transmission connector

well done Christian and Vera. Another great video, so in depth, hats off to you both for all your hard work, how much for one of your T' shirts if you sell them.

There's a little landrover knome hiding around the transmission area, he has a mini oil can and occasionally squeeze out a little oil just to confuse the situation.

Oil weeps through the aluminium of the casing in the base of the pocket around where the steel D clutch tube is embedded. Great video. Makes me want to buy a 2 post lift for my disco 4

Red is black and positive is negative, words to live by. I await your next video with baited breath. Good work guys.👍

Was it the gearbox vent tube leaking? Another quality video too.

another great video,. The more I see work on the D4 the more I love my D3. Keep it up.

Regarding corroded bolts, I always give the heads on mine a light covering of a thick grease. As long as the bolts are not directly in the path of road water, it prevents the heads from corroding. Note that I only grease the bolts once they are in place, I don't apply any grease to the underside of the bolt heads.

I love the LR bashing you're vids promote because it enables you and me to get these cars cheap eg our D4 SC bought for 32kAu with 95k klm..now insured for 54k! Best car we've ever owned and makes Nissan and Toyota 4wds look like over priced dinosaurs....which they are!

Leak was on the transmission breather pipe where it inserts into the transmission. There is a post on AULRO detailing this problem including an image

That car is a steal buy. Almost new. Great job guys! The leak maybe because of the cleaning that was not fully dried. It seemed very minimal taking a look seemed its almost next to none. Everything is easier with you guys!

many thanks and Vera & Christian for another great video

👋 I think it's from the transfer cooler pipes. Fantastic video.

When you pulled the transmission pan without removing the exhaust and raising the engine I thought, “How lucky they are not to be working on the 6HP26 with the V8.” Then I saw your transmission fill procedure for the 8HP and I realized there is no winning. Good thing we love these cars and we are “mechanics”.

Love it, great Sunday evening watching 👍

I started looking into LR3 and knew they are a bit of real estate. But this scares me and I had history of similar complex cars such as Audi A8 which I wrenched myself. But thank you guys my wallet will be happy and wife even happier. Nevertheless I'll continue to watch as it's very educational and also love Toyota bashing.

Another great video. Normally they leak from Valve Sleeve Vacuum Control(the connector plug - LR023292) which has several o-rings.

I saw video my time 6am. I understand there are issues with the rear of that particular transmission ie: small crack or hole at the bottom right. It Can be fixed with metal putty to stop the leaking. Sorry about the time difference. Great video. 🤞🏻

Greatings from Melbourne.....Christian and Vera Great team work, love love your videos. I have owned 2 x Discovery 1 300 tdi one I rubbed back to aluminum and the other white, now i drive an MR triton ute keep making great content please Aussie Jack

It was the oil filter cap that wasn’t tight enough 😂😂😂

I think need to shield the on-the-fill cap on the transmission. Greetings from Iceland 🇮🇸

A blocked breather from me. Great video both, thank you.

Rocker cover seal. Great video again👍

Feel your frustration. Just sent my in for timing belt, oil and water pumps, a pair of EGRs replacement and plus a major service to drop all the diffs and transfer case oils and transmission. The guy i used here in down under is a LR specialist. I which i can do all the work myself.

Another great video, thankyou for supplying your newest Patreon with Sunday morning entertainment , Paul

I've always done my own work ever since we had an unfortunate experience with a mitsubishi dealer many years ago (35 actualy) doing it yourself means you know it has been done and if it hasn't worked you know what you did or didn't do. My investment in a hoist and a shed load of tools was worth it. There is no satisfaction quite like making or fixing something.

And no I do not know where the oil leak originated , love your channel guys

Maybe the transfer case vent ?? Great videos great team work 👍🇬🇧or gearbox vent

That post makes me wanna send my D3 to your house and stay there for 1 month for full check! :D Congrats on your work!

Hey Christian and Vera, I'm sorry to see that you have been hit by so many Land Rover dealer mistakes, but it is good for the channel. Haha. The worst of it on the old Mall Crawler was your oil level sensor, but that was a design flaw and not the dealer I guess. This Discovery 4 will give you plenty of videos!! Haha

this video was funny for various reasons and informative at the same time, something not every youtuber is able to achieve.

Keep up the good work!! My wild shot here, transmission cooler lines or cooler was leaking!!

I think that the gearbox breather may have been pinched / blocked when a previous repair from the dealer was done. They’ve obviously been under there to service it and try and fix the noise

The leak Is from the mechatronic connector sleeve… but u need to remove the transmission Oil Pan in order to move the lever to release the sleeve. Need to replace the gasket and new Oil again.

Yet another great video and more quotes from Vera. "I'm going to make lunch now, I'm depressed". Don't know what the cause of the leak was but really looking forward to the next video to find out. Thanks for posting.

Good one. I am.i stalling a hoist. Did concrete work last week. Ashade is to flow as it is very sunny here in Dar es salaam

Fab video guys. Thank you! Very informative and confidence building 🙂 I am about to tackle fitting new differential bearings front and rear shortly.

One of the transfer case housing bolts required thread sealant as it passes through to the transfer case internals where there is gear fluid? I hope it doesn't, though you do see that in engines where bolts pass through water and oil galleries.

I think the leak was as simple as the plug washer above where the plastic cup was placed. The one with the drip actually on it. I’ve seen hard or burred washers on drain and fill plugs many times.

Hope you used enough devcon putty and filled those 2 cavities that leak due to porosity issue of TC while it was out even if your leak was from somewhere else, looking forward to the great reveal on Sunday👍

My goodness that two-post lift is a complete godsend isn't it? I wish I had one (for my 2007 Citroen C5)!

Very interesting and entertaining, Christian you must be a very energetic man.

Great video as always, I've just purchased a discovery 4 I think Christian would love to have a look over, it's a 2011 sdv6 hse with a mere 360000km with full land rover service history 🙈🤦 I will report more once I give it a full inspection when I w9rk on changing all oils and filters 👍🏻

Because it was dripping from a bolt my guess is the bolt has been installed by Land Rover without a sealing washer. You have since removed bolt and fitted a washer and replaced.

Great Video, keep it up guys. When this happened to ours the shaft between the gearbox and the transfer case had very slighlty gone oval so needed replaced. So i am guessing the output shaft had gone out of round from the gearbox and couldnt reseal

My guess for the oil leak is from the multi-pin electrical connector at the RH side of the transmission.

That free oiler is keeping the rust at bay 😂

Amazing video's! I really enjoy watching your video's, the banter between you two also make me laugh!!

Great job you two work well together see you next week 😁🇬🇧👍

All the oils taste slightly different. Just a touch and you can recognise what is leaking. The cause of the leak is that you have a Land Rover. I had one and it used to leak so much and burn so much I never had to do oil changes. Just keep topping up and change filters as appropriate.

I wait with baited breath for the source and fix of the transmission leak.

Comment no. 3 The Toyota screws weren't, when tied/closed, applying sufficient pressure to hold the assembly together as needed. This allowed, in specific situations for ATF fluid to gather in a low point and leak.

I think it must be the seal from the gearbox output to the transfer box. If not then it is the gearbox breather hose blocked. Love, Paul.

Owning a Land Rover is always a debacle of love and hate.

Firstly say I really like your videos. Thanks for the time and the effort to make them for us... It is a lot of work. Second, I don't own any Land Rover from 1998 on... all my landies are basically Tdi's, is not the same as Discos 3 or 4, I know but I don't drive long distances cause here in Gran Canaria the longest highway is 70kms... lol I still enjoy the videos and you guys as a couple working together! About the failure... Maybe a casting fail during the casting of the gearbox facing the transfer and oil gets the drain hole, and there you go, you have a leak in there.

Have watched rhe video a few more times. The point where you bolt that you pointed to have oil is at a higher point than the oil pan. So the pan is out of question. Its coming from a place higher than that. I have tried to search for known problems /recals and my conclusion is "It is the transfer case housing it self, poorly manufactured, porosity within the housing material" The T shirt is mine. A toyota die hard, who currenly drives a nissan and soon it will have LR sticker
