- My D40 was sluggish and smoking somewhat I run through a simple DIY at home and find some interesting problems along the way …..faulty vacuum pipes
- แนวปฏิบัติและการใช้ชีวิต
I've got a 2012 R51 Pathdinder
140kw 2.5 YD25 Manual 6 speed.
40mm lift, Bullbar, winch, rock sliders, 265/70/17 tyres etc etc
I have installed a Mann Provent catch can/oil separator and EGR blank.
Has snorkel with KN filter and Pre filter fitted
I Run Water Wetter in the radiator and 5W-40 oil with a splash of Lucas Stabilizer.
Just did 20,000km around outback Australia towing a 2 Tonne Caravan.
Diesel consumption average 14.9 litres/100km
No CELs.
No nailing on start up.
No black smoke.
No engine issues at all.
I'll be doing this on any future YD 2.5s I own
A belt or strap to remove the oil filter would probably work so much better than the awkward filter tools you can buy.
I have a similar issue with my 2010 D40 YD25 239000km. It was an auction buy so was expecting problems. I haven't checked the hoses but I think I'll go ahead and replace all hoses with their silicone equivalent for peace of mind.
Sure hope I can have a smile like yours after such works...
On the EGR blank I would advice you to get a stainless steel plate I used the same material plate that you have used and it got chowed away and eventually I went for stainless steel and It was sorted
I’m challenges with my D40. Gear 1 seem not to be pulling well. I also got it off an auction. Now on 300000km.
By fixing those vacuum lines you just got all your boost back. Didn't need to gut the cat. But now you have it doesn't matter lol. Enjoy
👍👍. But first thing I do with any of my vehicles is gut the cat and usually drop in a less restrictive muffler. Engine dynamics wants air to move with as little restriction as possible. Cat is unnecessary restriction
Vacuum lines hey?? Sorry but you shouldn’t comment on what you don’t know.
@@Seegsoutdoorbut it’s also destroying the planet hmm😅

Hi did u only blank egr on the one side coz I blocked mine only on the one side and now my turbo stopped working
Blanking the egr should not stop the turbo operating. You need to go check that all the vaccum pipes under the plastic engine cover are plugged in. Possibly one came loose after working on the egr blank off. Failing that check the solenoid the works the turbo actuator make sure it’s engaging the actuator
Heya. I've done a muffler delete tried to remove the cat off back of turbo but had no luck. Bolts were a mission. Thinking of trying it this way also..... any tips? And was it much louder at all. Cheerd
Hey Scott. I’ve been in the muffler industry for over 20years. And I know removing that cat from the back of the turbo can be a real b#*ch. that’s why I generally opt to do it from the bottom of the access allows. Unless I’m doing a downpipe conversion on this model no reason to remove the cat. Tips. Spray penetration oil the day before on the three flange studs. Other than that is pretty straight forward as in the video There is more turbo whistle but not exhaust sound. Next month we will be cutting the muffler out and fitting a smaller free flow unit. Will do a video on that and hopefully get a little more sound out of the lady
@@Seegsoutdoor ahh awesome. Yes I managed to crack one loose but patients wore thin for the other ones 🙃 . Thanks for the reply. Back into it this weekend.
Did u finish the cat delte
Have you ever been pulled over yet or any problems with getting rego since hollowing out the dpf
Hi there. We don’t have regs that that here in our country. Well not yet. And the regs that are there are not policed very well.
How much did your fuel economy improve since you’ve done it?
I have done a lift kit and larger diameter tyres so I haven’t noticed a saving but the current consumption is fair considering the other mods
How do you even get it all out of the cat, I got probably 3/4 of it out and couldn’t get to the rest because of the angle so I gave up 😔
I used a long wood drill bit with a sharp point to get to the weird angle
Hey may i ask? Anyone can andwer hopefully, if i remove the stuff inside the cat, does it make it excessively loud or just right?
Hi there Jex. It doesn’t really change the sound much. You might hear the turbo a little more. But the main muffler is huge. That’s were most the sound is muffled. If you wanting more sound have the main muffler cut out and install a smaller free flow muffler.
How's your car performance after the cat delte
Vehicle pulls well. But we also fixed the perished vacuum pipes at the same time for the turbo actuator so most of the increase in performance would have come from there
any faults on the dashboard after removing dpf?
This model has no sensors on the exhaust. So no issues
@@Seegsoutdoor what year / spec do you have ?
Spain spec. 2007 YD25
Guys please rply i have a d40 2007 model 2.5 i want to know if your EGR is block is it good or bad?more power lighter on feul or what?and the DPF /cat to remove that is that also bad thing or good thing give it more power the moment you excellerate?
We have blanked of the egr. Haven’t noticed a power difference but what it does do is stop all the carbon from exhaust mixing with blow by oil and that starts grimes up in the intake manifold. At the current milage when I have a chance would like to remove the intake manifold and give it a good clean. That usually does make a power difference. The cat I always remove from my vehicles does make it a bit more responsive fuel I can’t really answer because I’ve increased the tyre diameter and fitted a lift kit both those mods affect consumption currently i get around 9.3km/l probably would get more if I was a little light footed . But if you feel you lacking power start with all the vaccum pipes they are very often the culprits affecting the actuator for the turbo
Oky thanks wil do the same and check how it goes thank you
Please tell me on a d40 nissan navara 2.5 4x4 for clutch adjustment my clutch it takes a bit higher i want it to take bit lower what can i do please help?
@@denchillvanrooyen2707 hi there. Unfortunately I haven’t come across that issue as yet. You could try adjusting the nut/pushrod on the back end of the pedal short of that not working it could mean that you due for a clutch replacement soon
Good day please tell only in the morning that white blue smoke what could it be it's only in the morning...my egr is blanked and has not cat in but it use no oil no nothing got lots of power but that smoke pla my.
Did the engine run hotter after the Egr block plate
No not at all. In theory if you are blocking the hot gas being recirculated then it should in theory run cooler
@@Seegsoutdoor in theory it would indeed run hotter, because there will be more oxygen and compressing the oxygen will generate a lot of heat. But it should still be fine, since as you said EGR is because of emissions regulations and not actually to protect the engine from overheating.
thank you video !
I sir need some advice on these bakkies
Hi there Ashley. What sort of advice are you needing ?
@@Seegsoutdoor this EGR DELETE that you did is it A DIY job or should I take it to a mechanic
@@ashleyjosephus3898 depends how often you swing a spanner. It’s pretty straightforward most difficult part is making up the blank off plate and getting the internals of the CAT out. I would suggest and exhaust/muffler shop to remove the internals of the CAT for you it’s just easier than lying under the car and doing it. That took me quite some time with lots of muttering.
@Seegsoutdoor thank you so much for the advice really enjoy your your video .I will definitely blank it off and let a exhaust place remove it
Mate I Did the same with the dpf but my car is on limp mode now, any clue on what has happened?
You would most likely need to do a DPF delete on the software. My model doesn’t have sensors on the cat so no way for it to réalisé it’s been removed
You need to buy a new dpf the software in our d40’s won’t run without
Guys do not do that, the engin will blow up soon. Nissan engineers are not stupid
Nissan engineers didn’t make this because they clever. They made it to adhere to emission regulations forced on by government. You have no idea what you are speaking about. We have been doing this to our vehicles for years without blowing up engines. In fact more chance of long term damage with an egr than without
I cleaned out my cat converter now I can’t get it over 2000 rpm why
Which year model? And does you cat have a sensor on it ?
07 and yes a sensor
If it had a sensor behind the cat the computer is picking up an issue and putting the vehicle into limp mode. I’m not sure your side but here by us there are guys that can program the computer to overlook that sensor that should solve the issue
I have a scan tool and it is showing a R2002 code over accumulation in the dpf but that was already there before I cleaned out the cat converter, I was getting about 4500rpm before I cleaned out the cat converter but now it’s gone down to 2000rpm. The sensors are just before and after the dpf. There is hardly any pressure coming out of the tail pipe so maybe the problem is the dpf. Do they override the sensors with a scan tool or something else. What do you think.
@@eddieellul4350
Try the Nissan ECU reset shoe shuffle.
Sounds like you're in limp mode
10:23 lol
😂😂 was a stressful moment
If its a manual it wont have a dpf. It'll just be a cat. The autos had dpf
Which means no blocking egr for auto unless you have a solution?
@@13965082 I blocked off the egr and it went into limp mode and it rinsed the stepper motor for the valve
Blank the number plate
All that crap is worth big money
10:25 mdrr
