In this video, I'll show you how to assemble a yd25 Navara engine. Engine build yd25.com.au/index.php/services-2 workshop manual navlife.com.au/d40-series-ser...
Thank you for your time and video, I just replaced a fuel pump, that some one almost got out and left in pieces and parts and I rewatched your video 100 times just to make sure I got it 💯 right , also i needed a computer to plug in and let ecu know it was a.new fuel pump .
Just got my Nissan 2010 D40 Thai engine done by the boys and picked it up last week, we got all the mods too, I can't say enough about the great service & support they provide. I would recommend them to anyone with a Nissan D40, thanks Daniel & Paul
@@negueba235689 I removed and reinstalled it as well did the mods etc. (I am an auto sparky which helped) and Daniel & Paul did the engine side up to the video above. I have never done engine rebuild etc. but found this to be very easy and the guy's really support there service.
I have a xtrail t30 d22 which is dying with a cold engine. Ibsuspect the timing chain is worn after 250tkm. Is changing the timing chain similiar to your assembly in the video?
Hey there mate, awesome video. Thanks for the info. Im corius though about why you torque to head bolts to 44 N/m when all the manuals I have seen say 39 N/m.
We sell bare long engines that way all the important machining and measurements are done properly but can sell parts as well. yd25.com.au/index.php/services-2
Well presented and skill.👌 I ve 2007 D40 VSK engine I rebuilt the engine from scratch as per your guide and all seems well and good except that at times when I restart the engine it sometimes drives with super quite smooth idling and at times little bit rougher but not easily noticeable by someone who haven't driven it for long to understand the difference engine sounds. Secondly ,it also sound smoother than normal when diesel is almost finished when below quarter tank gauge level.What will be the cause of these? Lastly, when rebuilding the engine I rebored the block and replaced the cylinders with the max size "40 thousand size" I sometimes feel like the standard turbo is now smaller for the power it now has as the booster solenoid keeps failing to boost although the engine still remain powerful enough to climb hills even without turbo boosting. What other turbo type and size can I use to upgrade it?
I have just done a new head on my YD25 from a 2006 D40 and when I start it, it idles for a few seconds and stalls out. It runs pefectly fine if you just touch the throttle. There are no codes when I plug in the computer. Any Idea what it could be?
@@julianmillgate5990 if it runs and doesn't want to stall like usual means either chains are out or cam sprocket not lined up on dowl or tone wheel not lined up
Absolute legend, fantastic video mate. I just bought a 2009 2.5l Pathfinder and I have an annoying ticking sound on acceleration but only up to 2000 rpm, then I can’t hear it. Worse when the engine is cold. Any ideas mate.
@@yd2532 188k Supposedly the timing chain has been changed to a double row chain, but the injectors have never been done… well the last owner never did them and he had it for the previous 3 years.
This is fascinating as fk... I would only dream of rebuilding my engine.. might have to one day since I've remapped it 5 years ago go a rich fuel/air ratio..just waiting for it to blow Q: Why copper hammer? And what kind of silicone? Is RTV thread sealant fine?
@@yd2532OMG !!! You are the best!!! This is gold for me !!! Thank you very much ... I am currently working on a truck with this engine (YD25DDTi) that's why I searched for videos on the internet and found yours... thank you very much you are a great person for sharing
@@yd2532 than you very much !!! you are amazing, I am currently working with a Nissan truck with this engine (YD25DDTi) and this is a great help to me, I am very grateful to you for sharing
Maybe you can help me with a d40 that blows grey and blue smoke after it warms up. Strong diesel smell. Motor runs fine. Good power. Has new injectors and engine was rebuilt. It started happening about 2 weeks after the rebuild.
@@richardherring76 could be low rail pressure do an ecu reset or change the scv. Or could be low compression make sure you put the engine under load to help the rings bed in
Great stuff mate. I have a d40 with a very annoying ticking sound in the top of the cylinder head I have had the shims checked which are all within spec and new injectors which it needed I have no gasket leaks it is doing my bloody head in any ideas 🤯🤯🤯 i have been told it is just a noisy engine which doesn’t make sense to me 🤔👍👍
@@yd2532 sorry mate I forgot to mention it does have new timing chains as well ,hence that is why it is doing my heading . Thank you so much for your reply 👍👍👍
I had similar issue and I noticed the fuel pipes were sucking air into the system and that the water separator filter drain plug wasn't fastened tight enough and after tight fastening them and doing an on engine suction control valve and injector system cleaning, it become so quite and sounded like as if it was a petrol/gasoline engine

probably the clearest and best rebuild video i have seen, perfectly explained and very well done
Thinking of getting a Nissan Caravan with a yd25 and started doing homework with this video. Thanks.

Also, the car is going great had no issues at all,
Just got my 2007 ST-X D40, totally saving this video for future reference. Super informative
Díky za video moc pomohlo👍 zdravím z České republiky

Awesome video! How does the failsafe for the tensioner work? Does that come standard with the kits?
Takes up the air gap so it can't go back in all the way and have enough slack to jump teeth. We make them and include it in all our kits
شكرا لك على التوضيح
thank for your video
Greats job👍👍
Lovely video
good sharing sir. It's same Nissan navara d23/navara np300.
Hey there mate, awesome video. Thanks for the info. Im corius though about why you torque to head bolts to 44 N/m when all the manuals I have seen say 39 N/m.
Wow ..thank you.
Just out of curiosity, what grease are you using for the head bolts?
Can you please do a video on how to remove the engine?
Great info. Do you guys sell a complete diy rebuild kit
We sell bare long engines that way all the important machining and measurements are done properly but can sell parts as well. yd25.com.au/index.php/services-2
Great video dude. When u said, use silicone under the timing chain cover seal. What type of silicone should be used? I'm about to replace the seal.
3 bond super sealer grey
@YD25 Thanks mate...
Thanks You
This video is great just what i needed. Can you 1 for zd30 engine please🙏
Great video 🤟 at what mileage would you consider replacing the timing chain? What brand of timing chair would you recommend? Cheers love ya work👍🤟🤟
Average chain life is 150 000km. We make double and single row kits www.yd25.com.au/index.php/services/yd25-duplex-timing-chain-conversion-kit

Hope you will upgrade the timing chain to a stronger duplex timing chain set up.
If u watch the video that's exactly what it has on it

See if it runs if you disconnect the cam angle sensor
It’s running with the cam angle sensor out, does that mean the timing is out?

How many KMs

Supposedly the timing chain has been changed to a double row chain, but the injectors have never been done… well the last owner never did them and he had it for the previous 3 years.
@@adventurecampexplore5496 injectors usually go around 300k unless they have been over heated or had dirty fuel. You could measure the chains
@@yd2532 So you think it could be a stretched timing chain.
@@adventurecampexplore5496 potentially depends on the brand of chains that were fitted and if it was fitted correctly
Can you guys fit the double row timing chain?
Yes

Wow great video. Can i ask for workshop manual. Your help will be appreciated

This is fascinating as fk...
I would only dream of rebuilding my engine.. might have to one day since I've remapped it 5 years ago go a rich fuel/air ratio..just waiting for it to blow
Q:
Why copper hammer?
And what kind of silicone? Is RTV thread sealant fine?
copper hammer is soft so doesnt damage parts, we use three bond super sealer grey

Worn timing chains can make a ticking noise. Sometimes the cam chain guide can snap as well and rattle
