MAKING YOUR TDV6 DISCOVERY 3/4 MORE RELIABLE 

Thanks for the tips Ryan, I purchased a D4 with the 3lt a year ago, motor was rebuilt by Automotive Skills and seized up three months later. They rebuilt it again and now pissing oil leaks from the top LHS and RMS, having nothing but dramas. I'm only an amateur mechanic, but love the vehicle enough to just put up with the garbage. These tips help.

Great Video mete. As a new Discovery 3 owner. I have checked a lot of things. I know my oil pump got changed but will now check that it is the reinforced one. Will also clean the sensors and double check my crossover pipe which was also changed by last owner. I have a very slight coolant leak. I did see a video about the coolant release valve which I am yet to check. Thank you so much for what you do. It helps so much to have people like yourself making videos to help the rest of us who are still learning. I am in love with my Discovery. God Bless

Many thanks, great advice . Much appreciated from the UK

Hi mate, new sub here. I have a 3.0lt D4 and just came across your channel, liked what I’ve seen. I was on a trip 2 weeks ago (800km) from home and that coolant crossover let go I just removed the coolant reservoir cap and topped up my coolant when the low coolant light came on for the trip home, I used 9lts of coolant. I’ve owned my D4 for 9months and it’s been an interesting learning curve. Thanks to channels like yours and the AULRO forum the answers are usually easy to find. 👍🇦🇺

Very handy information and sound advice!

Great suggestions and practical help.

Thanks brother such good advice man. Just brought a D3 with no servive records so I will definately be doing these items

Regarding changing engine oil and filter, it is so easy to get under a Discovery 3 or a Territory that there is no excuse to drain and change the oil yourself. The filter housing needs a 32 mm socket, and remove the filter housing and the filter carefully, but it is not a difficult job. The most important thing is to replace the O ring around the filter housing exactly the same as the old one. Check this over and over, otherwise you will get a leak. As for the oil itself, I do agree with you. I use a 5W-40 ACEA 3. As for the carbon inside the intake manifold, I squirted in degreaser through the same air pressure sensor hole you highlighted - with the engine running, squirting for a fraction of a second for many times, and without the engine running, about five times each time squirt for about three seconds and then restart each time. Watch the puffs of smoke out of the exhaust. I recommend doing this every month, and the engine runs better.

Thanks for your video. I have a Territory diesel, and I am learning as much as I can about the potential issues. I knew nothing about the coolant crossover, but I immediately bought a spare after watching your video, and I havent even got to issue 3 yet!

Great info.m8 also relevant for my Range rover Sport !

Great update Ryan, good to hear from you. More jobs on my list for my replacement engine change 🤣👍

Top👌 A hug from Portugal

Great advice buddy

many thanks for this video, I'm on the way for MOT and will have to do all the jobs. Is there a pdf list with part recommendations?

Great vid Ryan cheers mate

My Advice use Good Quality Diesel Fuel ideally with a Fuel Additive to raise the cetane number and improve lubrication to pump & injectors. Change fuel filters early don't go to what the workshop manual says .........ideally every 25 - 30 k. Check the throttle flap - its made from plastic which gums up or swells and sticks ........causing fault codes and drop in performance. Clean it out and file a bit off its outer edge to prevent sticking.

Great video Ryan. I’ve got a 2016 tezza diesel and wow the map sensor was so gummed up. Can you recommend anything else parts wise apart from the coolant cross over piece and latest spec oil pump?

My new oil pump fomoco from british4wd leaked after i replaced it, 1st was the crank seal, buy the rubber generic "toyota" type not the genuine type, look for pics you will see the difference, 2nd the pump leaked from the hex plug where you check pump pressure i belive. This caused me a head ache and shoulf have come from factory sealed. (Leaked past threads once warm and pissed oil out quite heavy) check that before fitting the new pump guys. Peace

There’s a nice V8 for sale in WA mate 😂. Congrats on the 3k.

Good day Ryan. Do you perhaps know what the part number etc is for the new style oil pump, I live in South Africa and I would like to see if I can buy the new oil pumps here? Many thanks.. Ray

Great advice Ryan. When I bought my Discovery 3 TDV6 4 years ago this December my coolant level light came on so topped up about 500ml. Sure enough about 3 weeks later it came on again and more coolant was missing. So I changed the coolant crossover and it solved the issue immediately. You could actually see where it was leaking from. They have a seem where 2 halves of the crossover are joined and that seem breaks down over time. Really poor design I reckon. It bugs me why people don't love and cherish their Discovery 3's and don't just replace parts when they're worn or like you stress, incorporate preventative maintenance? I have since gone on to practically rebuild the vehicle due to parts looking tired over the last 4 years and now have a very nice reliable Discovery 3, or at least as reliable as you can make it 😂 Hope you're all settled in the new home now. Love watching your new uploads and admire your strength and determination when dealing with your Discovery 3. All the best for Christmas mate, take it easy and enjoy yourselves 😊👍

The supercharged 3l v6 in the D4 also has plastic cooling cross-over pipes that fail. There's aluminium replacement pipes available from the USA eg via Amazon. The revised plastic LR/Ford pipes aren't much better. The rear plastic heater manifold can also fail as can the original water pump. If you buy an SC replace the two plastic cross over pipes with Al and the water pump/heater manifold immediately. Otherwise the SC V6 is a great engine. Plastic pipes...why do it???

👍👍👍

Hi could you please let me know who in Australia (I'm in Qld) supplies the reinforced oil pumps? Cheers appreciate your vids

I cleaned my sensors with break cleaner a couple of weeks ago, seems to be fine, what issue can the break cleaner cause, will it damage the sensors? Great video

Hey Ryan, any tips for the new Ford Ranger 3.0L V6 engine? I understand it's the same engine as the Land Rover. Is there any differences/upgrades that you know of? Cheers Gaz

Great video man thanks for that. I only just bought an ‘05 model that needed a bit of work done. I’m definitely going to take your advice on these issues. The engine on mine has done 240k, when I got it I did all fluids, noticed that the diffs hadn’t been done in a long time, and I’m assuming the engine oil was the same. I did notice a little bit of shiny stuff in the filter, and it has me worried the engine is on the way out. Just wondering what your thoughts are on this? I was planning to keep my oil changes to every 5000kms. Just seeing if you have advice on whether I should cut my losses or whether it’s capable of being maintained? Also, do you have a recommendation on the best place to purchase parts in Australia?

hello where did you get the metal coolant crossover flange from I can't find them anywhere?

Thanks for the heads up, IM also in S/W WA and have just developed an int leak on the injectors on my 2016 SZ MKII Territory. Do u know of anyone that has done a 3L swap into one of these?

p̲r̲o̲m̲o̲s̲m̲ 💥

None of that stops the crank breaking , dreadful engines 😅😂

I think I love you, but not in a broke back mountain kinda way

Simply DON'T by a bottomless money pit of a vehicle!

No need to watch the entire video. The obvious answer, is in the question itself. Just. Don't. Drive. It

Great Videos as always Rayan 🫡 Mate I clean both MAF & MAP sensors and nothing changes to my Disco 3 I don’t say you wrong or something NA mate just I’m trying explain my situation on what’s happening with my disco ! I checked both works great just it might be something else ? I have the HIKE IT X9 installed on my Disco3 since I bought it do you reckon it might be it the reason it’s eating to much Bro 🤦‍♂️😂😅! Have great week start with cheers Matt 👋🫡
