Turbo Lag - Navara D40 YD25 - BCV/Trubo Solenoid Replacement & Alibaba Silicone Cold Intake Pipe

[@HuntingandfishinginCyprus]

6 months ago i had turbo failure...i thought I should change or repair it but in the end i figured out that the plastic pipes ending on that part the exactly same you change in this video was damaged and lose air so the vacuum didn't worked properly so the turbo didn't worked either..thanks for the video and the informations you shared

[@PrimalNomad]

Thank you for watching and commenting! Glad to help anyone if I can!

[@bananaking2828]

i keep a cheap $5 obd2 scan connected and bluetooth linked to a disused mobile phone. i call up all variety of gauges on it. monitoring the boost pressure is very easy.

[@PrimalNomad]

I also have one of these now and it's linked to torque. Like you mention its a great monitoring tool! Thanks for sharing & watching

[@FlorentLor]

Not actually all that into mechanics, but I just watched the whole thing through and had a blast ;)

[@PrimalNomad]

Thanks so much, I was never really into mechanics either and it's just something that happened. Really appreciate the comment!

[@rx-7813]

hey! before you change the solenoid, does your turbo actuator goes up and down non stop when idling?

[@andrewhickson7776]

Mine does and still does . Replace the solenoid but must be something else as still doing it

[@jeffreystorer4966]

Good on you but did it make a noticeable improvement a test drive after would be nice thanks

[@PrimalNomad]

It definitely did! Thanks for the heads up, I'll make sure to next time 🙏

[@jeffreystorer4966]

Ok cool I been given my o8 D40 bit of a tidy up. Go n for hard pipes next clean throttle body yesterday n is run n sweat but pipes do suck in thanks for your help

[@PrimalNomad]

No problem at all! Ill hopefully be releasing a load of navara stuff soon, I've built up quite the collection of videos 🤣

[@Yorkshiremadmick]

The clip on the vacuum you replaced with a jubilee is designed to be circular pressure when tightening. A jubilee doesn’t tighten fully circular. You May have issues drawing in air. 👍🏻

[@PrimalNomad]

Thanks Micheal! I'll double check it and make sure that it had a good seal, if not I'll get one of the original clips. Appreciate you mentioning this!

[@Yorkshiremadmick]

👍🏻

[@بدر-ر6ظ]

thank you my friend. How do I know if a solenoid is good? im weak Or disabled??? 🌹🌹🌹🤝

[@PrimalNomad]

Low or inconsistent boost pressure is a common sign, also lag on the throttle :)

[@بدر-ر6ظ]

@@PrimalNomad Yes, the reinforcement is inconsistent. Another question. Is the Chinese turbo? Good or not. Is it a Taiwanese turbo? Good or not. Thank you

[@PrimalNomad]

@@بدر-ر6ظ hi! I'd suggest a garret replacement turbo, and the solenoid from denso/nissan if possible. Some people have said that the Chinese ones work okay but others not

[@بدر-ر6ظ]

@@PrimalNomad good thank you 🌹

[@rworsdell1986]

Nice video. I've just replaced my hoses for the BCV. Could you tell me does the BCV pulsate with the engine running? If so is it a steady pulse? Told its supposed to but mine does sometimes and not others. Thanks.

[@PrimalNomad]

Thank you! The bcv would pulsate under load as the solenoid would be working opening & close with the vaccum. I don't think this does happen fully unless the turbo is spooling though so might indicate why on idle there is less movement.

[@AmazeMJ]

I personally find my d40 lacking torque in the lower rpm range. Did you notice that with your own? Does the hot pipe replacement help?

[@PrimalNomad]

I did notice that also, the hot pips definitely helped with it in some ways. It's taken the ability for the pipe to swell out which caused some noticeable power loss. All around its been a great upgrade and one of the first that I did!

[@meltdownzero]

dude i have a nissan d40 ive watched some of your more recent videos your truck is gorgeous, i have 08 plate dounble cab mine needs a new radio it has the orignal stock sat nav inside which is useless but i plan to look for a radio with MPG/fuel monitoring, and more engine management specs, theres so much i want to do my D40 i dont know where to start

[@PrimalNomad]

Thanks so much mate! It's been an awesome project, I've got loads of editing to do on footage from last year to release soon too! An OBD reader could help with the mpg reading etc on an app called torque! Also can connect it to your phone or an android head unit 🙏

[@meltdownzero]

@@PrimalNomad have you got any videos replacing your turbo lines and any links for BCS, not getting any fault code just my nav feels sluggish.

[@yourrandomdude5860]

This video popped in my feed, I'm wondering does the d40 engine usually gets peak boost at around 2,200rpm? Or is that to higher than usual?

[@PrimalNomad]

That's about usual for me, it's sometimes a bit lower but usually is a bit late to kick in. Have you got a hard pipe or still running the rubber pipe from the intercooler to the turbo?

[@yourrandomdude5860]

@@PrimalNomad I’m still using the rubber pipe, does changing it to a aftermarket hardpipe will reduce the rpm needed for the boost to kick in?

[@muzzaball]

Thanks for the vid, I have the same vehicle and I replaced that turbo vacuum solenoid too. I wanted to replace my old plastic intake pipe like you did, however the link you supplied to Alibaba only sells them 50 at a time - how did you get just one? Cheers.

[@PrimalNomad]

Thanks for watching! I managed to ask and order a single sample from the seller. They seemed happy to help.

[@jeffreycreman2605]

did you cut the other vaccum hose from the air filter?

[@PrimalNomad]

Hey Jeffery! Sorry I hadn't seen this, I don't think I did, but I definitely replaced all of the hoses. I'll check!

[@josiahsiduna9165]

Need help with the vacuum pipes connections

[@PrimalNomad]

Hey! What help? Mesaage me on Instagram or Facebook if you like :)

[@arnisevardsons665]

Hi’ i! I have qeustion i see in your video activator moving all the time it,s okey? I am asking abouth that because i have same and i dont understand the rison off that

[@aris2153]

I see the same thing, and it´s not okey, that´s a failure symptom

[@PrimalNomad]

Generally this is a symptom of a bad solenoid (BCV) but I'm still to determine how much the actuator should move with idle. The engine utilises the turbo to move exhaust gasses via the actuator. How still if yours when the engine is off, it shouldn't have lots of play.

[@johnshiny6283]

Hi are all vacuum lines 4mm diameter? Thanks!!

[@PrimalNomad]

They sure are :)

[@matthewsadler8175]

Hi there where did you get the pre made silicon pipe and the metal on too that goes to the intercooler

[@PrimalNomad]

The hot pipe (metal) is from forefront industries in Australia & the silicone air intake was from alibaba/Ali express and I ordered it as a sample instead of the 1000 minimum order 👍

[@jnep9756]

mine is not moving at all , at idle , i don't think i have vacuum , i pull all the hoses out , and nothing , no vacuum ...

[@PrimalNomad]

There's a vacuum pump over near the oil filter on the right-hand side of the motor. You could lose vacuum through any crack in the line, but also inside the brake booster which is vacuum assisted. Check the pipes from the pump and let me know! Good luck!

[@jnep9756]

It had low vacuum, something was jamming the solenoid , cleaned everythin , started the car and the wastegate was mooving like in the video , but now the wastegate goes all the way up when i start the car, and i have vacuum, i tryed to messure the vacuum and the solenoid has half the vaccum compared to the main hose from the vaccum pump

[@lucianbeukes6510]

Awesome... Thanks mate.. Will be doing the same to mine.. Quick silly question, is the actuator supose to move while the motor is just running?

[@PrimalNomad]

It should bob up and down slightly and open when you accelerate. Thanks for watching!

[@lucianbeukes6510]

Thank you so much 👍

[@PrimalNomad]

That's aweome! I'm so glad that you have managed to fix it and get your truck back to its former glory!

[@v.n.7495]

What should be the max pressure on the turbo? Pathfinder 2.5

[@v.n.7495]

In my car there is Max 1.3 bar

[@PrimalNomad]

Its max is supposed to be about 24psi or 1.65 bar but have heard of 30 psi! Thanks for watching!

[@v.n.7495]

@@PrimalNomad The injectors and the engine are very loud when it's cold outside. I thought maybe it was the turbine. I have new injectors and the pump too. pressure is ok. new maf and map. when I accelerate strongly, the knock stops. then when I'm driving smoothly again comes back. maybe you know something about it? winter works quietly for you? what could still be done

[@pawesiwek7177]

@@v.n.7495 mine is doing the same thing. After it gets into good operating tempts (oil temp around 60 degrees Celsius it gets more quiet and runs smoother otherwise it runs like old loundry machine. I am after injectors rencondishioning too soo now I am thinking of changing timing chain and gears even that I do not hear any rattle noise from it but the engine has at least 130000km on it now.

[@cheshardlow2809]

Awesome bro... you just need to throw away that crappy paper air filter and get a K&N your navvy will be a heap smoother

[@PrimalNomad]

Thanks mate! Yeah a k&n would be a great addition. Also tempted with a custom airbox too 😁

[@andrewbaxter9986]

I'm having a boost problem on my pathy. The boost pipe doesn't expand when squeezed and reved at the same time. When you say the actuator is that the rod underneath the waste gate? There doesn't seem to be a great deal of vaccum. I've just my vaccum pipes to samco one's. Any tips on what I should look at?

[@PrimalNomad]

Yeah the actuator is that, moves up and down on vacuum. Sounds like the bcv may be playing up, try giving it a clean with some contact cleaner or wd40 and a good blow out. Does there seem to be vacuum if you take of the lines and block the ends with your fingers?

[@andrewbaxter9986]

@@PrimalNomad when you say bcv you mean the boost solenoid? I've ordered a new one to try and eliminate. While the engine is on tick over the turbo actuator doesn't move, but when I take that pipe off and on again it barely moves. Is this down to the boost solenoid or a vacuum problem or is it the boost solenoid that creates the vacuum?

[@PrimalNomad]

Yeah the bcv is the boost solenoid 👍, it's what controls the vacum and regulates the turbo boost pressure, not the same, but similar in what it does to a wastegate on a petrol engine.

[@andrewbaxter9986]

@@PrimalNomad OK thanks, illfitthis new solenoid when it arrives. Hopefully that will fix my problem. I don't know what to look at next if it doesn't solve it.

[@PrimalNomad]

I hope so too, if not drop me a message on Instagram and I'll have a dig into what could be playing up. Maybe worth cleaning your MAF sensor too!

[@Scartworks]

Love your video man! But one question. Have the replacement turbo intercooler hose & air intake hose improved performance? Im intrigued.

[@PrimalNomad]

Thanks for watching! I've definitely noticed a difference for the boost, the older rubber pipes used to both swell and also vacuum in under load, these have completely eliminated that issue & also renewed the pipes which were starting to degrade so it was a win win.

[@Dyfiwildlifephotography]

Where did you buy it?

[@fredscheerle7592]

Very good, What OBT meter/scanner you use?

[@PrimalNomad]

It's the torque app on a Bluetooth obd scanner that plugs in under the steering wheel :)

[@lordofspeed4]

I would like to know, How does it work? What a solenoid's air characteristic?

[@PrimalNomad]

It regulates the vacumn directed to the turbo and adjusts it according to revs for your boost, when it's playing up you may notice a significant change in turbo lag or acceleration.

[@JoshCarra]

Fuck me I'm trying to focus to how to do this job!!but with that background music I now have too much anxiety to do the job and suffering with pdsd now

Like & subscribe done. I have Navara d40 it’s rev not goes above 3000 any idea what is cause? Thanks in advance

Thanks! Possibly the fuel filter has an airlock or is faulty. Does it drive okay up to 2.5k and go into Limp Mode or just struggle past 3000?

[@shuabibajwa]

@@PrimalNomad appreciate your reply, we had change the engine in car. At 2500rpm it’s good, but rpm not goes above the 3000. When I connect the scan tool it’s shows Crankshaft position sensor A Circuit & code come with PO335. Please advise me. Thanks

@@shuabibajwa no problem, possibly it could be your crankshaft sensor. D40 models it is located on the rear of the sump on the passenger side on the vehicle.
