Ok, I have been lurking on this forum for a while and got some valuable info from here.  

But I joined because I need some advice   So, about 3+ months ago, I was driving along and just lost power called the AA apparently, the EGR was gone, so he blanked it off and told me that will be good but I need to take it to the garage   After reading on here that most blank there's off any way I decided to just leave it

About 2+ months ago, I pulled out off the road and tried to accelerate hard, so I didn’t slow down the traffic behind me, that failed because I lost power

I pulled over and turned the car off for a few minutes it restarted as if everything was fine.

But over the last few weeks, randomly once or twice, I’ve noticed whilst accelerating, not hard, just normal accelerating, the loss of power, then it kicks back in after a few seconds

  3 days ago, I went to pull out of the parking space where I live and drive off got maybe 4 meters, and it just died

No shudder like it was out of fuel - so after looking at the forums, I decided to:

replace the fuel filter
cleaned up the battery terminals
cleaned the MAF sensor
checked all the fuses, including the 4th hidden fuse box

It still won’t start - it cranks but won’t start.

So I thought maybe change the Suction Control Valve as I remember reading that there's a code on the side, so I turned the wheels to try and get a good view here is the image:

Another thing that concerns me is when I took off the engine plastic cover, I noticed on the large rubber pipe going in near where the EGR was blanks lots of black gunk, which has obviously been running down the pipe could this be the cause I'm not sure what this pipe is for.

So I'm going to change the SCV ordered this one:
http://www.ebay.co.uk/itm/FUEL-PUMP-PRESSURE-REGULATOR-SENSOR-SUCTION-CONTROL-VALVE-NISSAN-NAVARA-2-5-DCI-/261587577717

What about this black gunk something blown that needs changing

I also ordered an EGR blank plate that fits better, as the AA guy used what looked like a universal one

Any Help or advice will be appreciated.

that looks like your intercooler pipe, they all do that on turbos, just make sure its tight and its all good, the black gunk is what you try to avoid by blanking the EGR, try this http://www.nissan-navara.net/45-d40-technical-library/53177-how-perform-self-diagnostics.html and see if you get any results, the scv doesnt normally stop the starting but it does effect power and idle.

Run through the diags first and see if you get anything

Do the ECU reset or use a code reader to see if there are any faults logged on the ECU.

Have a read of this as well, just to confirm it's all covered:http://www.nissan-navara.net/27-tec...ow-investigate-fix-engine-running-issues.html

Just a thought, Once you've checked the EGR valve has been correctly blanked off it might be worth checking the lower timing chain for stretch: http://www.nissan-navara.net/45-d40-technical-library/29565-timing-chain-info-how-inspect.html

Thanks for the links will check them out

I did use a code reader before anything else forgot to say that all clean no error codes

I did a ECU reset via the pedals method after fitting the fuel filter seemed to work as planned got 10 fast, 10 fast, 10 fast, 10 slow which apparently means no errors too

Will try the ECU reset again tomorrow and add the new EGR blank if its here

SCV won't be here until Thursday probably but even if its not that might as well fit it
will also clean up all that gunk

Apart from that god knows what it could be

How did the AA chap blank the egr? If it was a roadside repair I doubt if he used a metal plate, just something to keep you going.

Open it up and check the blank.

From what i remember it looked like some kind of universal plate with random holes, once the new one comes i will post some pics of it

what fuel filter did you use and has it run since you replaced it, its not unknown for after market to leak and not create enough suction to allow fuel to be drawn, pump up the bulb and see if it stays firm especially overnight

Fitted the new one today, so after the problems and still won't start it was a Mann make, also pumped the bulb underneath the filter until firm but will check it tomorrow to see if its still firm

How about adding a catch can. If that oil is coming from the intercooler, a can could intercept it before it reaches the intercooler.

I'm Not aware of how effective they are. I would be interested in opinions.

Ok so yesterday it was raining, and I was sulking because I couldn't work out what the hell was wrong with the truck but thought I will wait until tomorrow I will have the EGR plate and the SCV

So woke up today and got the EGR Plate and SCV from the postman went out to the truck and checked the primer bulb it was soft pumped it till it was hard again tried to start the truck NOPE

Ok, so I read somewhere that loosening the fuel cap while pumping the primer bulb can't remember the reason tried that, confirmed the fuel was going through the filter be slowing removing the middle hose covering me with diesel, so there was pressure there :frown2: not my brightest moment seeing as I just was pumping the primer bulb till it was rock hard

Anyway I retightened the fuel cap and noticed the lock flap was very loose doubt it did anything but bent the lock back so the flap locks tight as it should

Then proceeded to add the new EGR plate here is the one the AA guy had fitted

Could see where the EGR failed looks snapped to me just flapping around

After all these random things attempted to start the truck, and it started so let it run for a while turned it off restarted it

All seems fine drove it around the carpark, and it didn't stall, so something has fixed it not sure what

But one question I do have is the primer bulb is it suppose to go soft again once all is working I checked it while the engine was running and it was not rock hard just soft

Oh didnt end up fitting the SCV but will keep it as im sure one day it be required

The primer bulb will only stay hard if used before starting, as you have introduced some fuel pressure between the bulb and the main pump. Once the engine starts and the pump draws the fuel through the system there will be no pressure in the fuel lines including the primer bulb.

Now you've found out why we recommend blanking the EGR valve. This wee mod may be of interest as well: http://www.nissan-navara.net/22-performance-upgrades/26718-another-d40-egr-mod.html

Yeah i am considering buying one, can anyone recommended a decent one to get?

Once thats added is there anything else I can get to try and give it a good clear out?

Did you remove the broken EGR flap, it's not doing anything anyway, you don't want that working it's way to the insides of the engine.

Hi,

Was your EGR stuck open? Did you clean it first before installing the new blank off plate or just went to installing?
