Nissan ELGRAND who has one?

[lorenzovalenton]

thanks dvldoc for the info. . cant wait for tomorrow to start on some of my planned fixes.

Just came back from Makati, no traffic, had to speed up, noticed that the van is shifting but the noise is unbearable (parang airplane sa loob) . Before kala ko not shifting because of the noise parang naka high rev lagi. Anyone had this same problem? Im guessing now na baka problem with the turbo already.

just got accepted sa elgrand.ning forum, dami helpful posts .

Have you checked the transmission fluid level yet to see if it's full?

Also if you suspect your turbo does it boost normally, how is the power?

Here is a Elgrand fact, They do not have exhaust manifold gaskets and can leak causing a loud noise and loss of boost pressure. You can have it replaced with one from the Nissan Navara which is a asbestos unit. This might be your problem if you bleeding off boost because of a exhaust manifold leak. It would cause similar problems to what your having.

The above post smell like spam

Anyways for you 3.0 Neo diesel owners this is important stuff for you to know, It can mean the difference in driving or having dead turbo or blown engine.

The Neodiesels are prone to turbo failure mainly caused by having a bad MAF sensor that causes it to overfuel and overboost then the high exhaust gas temperatures frag the turbo.

The turbo is a Garrett 705954-8 some of the big diesel shops might be able to help you our or someplace like Speedlab might know a place to send it for rebuild if this has already happened to you.

This is a common problem with the ZD30DDTi engine. I suggest before you need to get it repaired or already need to invest in a exhaust gas temperature gauge and boost gauge for your van. I would also have the MAF sensor cleaned or replaced.

The engine crankcase breather is connected to the air induction system on the intake side of the air flow meter. This means the meter gets fouled by fumes from the crankcase. The computer gets incorrect readings from the airflow meter and adjusts fuel and boost levels to the incorrect readings. Thus the boost goes astronomical. A simple manual boost controller can help keep this from ever happening.

Some of the symptoms are things such as intercooler pipes sliding off, engine running rough, and higher than standard boost pressures.

Installing a oil catch can with filter media in it a DIY oil catch can works better in this application.

Helpful pdf for you 3.0 guys.

This is the reason I went with the 3.2. But the if properly taken care of the Neodiesel should be fine. Get that MAF cleaned or replaced and a filtered oil catch can ASAP! You can make your own catch can from a air water separator for a air compressor. A green scrub pad works great for a filter on the inside.

Nissan part number for the 3.0 NEOdiesel turbo is (part# 705954) also shared with the Patrol with the same engine.

[dvldoc]

Owning a 3.0 Neo diesel Elgrand is not a bad thing it's a powerful engine, it's a common rail set up. But if your going to get one do the modifications to the motor that will keep it running and keep you from having to replace your turbo.

Things you must do!!! Must is the key word.

#1 manual boost controller why? It will save your motor from the over boost condition caused by a clogged EGR valve or dirty MAF sensor. These are what kill these engines. They are prone to this from 1999-2002.

#2 Oil catch can with filter media. A green scrub pad works great, You can buy one from a performance shop or make your own.

#3 EGR block off plate. Must have a manual boost controller before this modification because it will raise your boost on the Neo diesel 4 to 6 psi.


Now for the mods.

Manual boost controller is pretty simple. Should be the first thing you get. Only 1500P to 2500P most places.




OIL Catch can.
Be sure to use a filter element. Foam works well like the kind in some air filters or packing material.

When connecting the hoses Please remove the restrictor from the Nissan hose and installed it into the inlet hose, its there for a reason so use it.

When connecting the hose make sure that once the engine cover is back on it does not touch.
The plastic cover vibrates a fair bit and can eventually “saw” its way through the hose.






EGR Valve blanking plate.







What your motor looks like without these mods or water injection to keep things clean.

Complete blockage at 85000K

[dvldoc]

Air filter fouled by oil mist in just 10000K this will kill your MAF sensor and cause the over boost condition.

Hopefully all these technical post are helpful to you new Elgrand owners. I am not saying don't get a 3.0 just know what your getting and be prepared to do the proper mods to keep it running. The over boost issue applies to the 3.2 Diesel in regards to the MAF sensor as well but not the EGR valve causing over boost.

I have all 3 mods for my 3.2 elgrand plus water injection of course. Plan to keep her running good for years.

Also get a EGT gauge and boost gauge if you can.



Filthy intake on a Neodiesel.



Heads are not much better.

Sorry the single post count then reference to someones business then giving a number to call about vehicles.

i refer to you my friend hes almost five vyears in the business right now he got wide variety of japanese car most specially elgrand you can txt me at 09XXXXXXXXXXXX kung gusto nyo ma view elgrand baka magustuhan nyo

But if I am wrong them I am wrong. Feel free to contribute to the thread.

Anyways back to the Elgrand.

Here is the ZD30DDI motors turbo. You would put the boost controller were the hose from the turbo to the wastegate is. Just get a longer piece of tubing and insert it.




This really is a do it yourself job. But you really need a boost gauge to see were your boost is set at stock so you can set it close to that or a few psi above.

The 3.0 also has a non conventional oil filter.

well sir dvloc cnsya na rin po hindi ko kse alam kung anong post yung spam natuwa lang kse ako dun sa elgrand na nakuha dun sa friend ko kaya naisipan ko na i post number ko just in case na may magtanong, anyway some part of my post is only opinion, my only concern for now sir is my aircon babalik ko ngayong araw for checking, thnks anyway

Hi dvldoc, my ZD30DDTI turbo is a variable nozzle turbo it looks different to the one in the photo,apparently ZD30's can have 2 types of turbo's, on mine the vacuum pipe goes from the vacuum control solenoid to the turbo actuator, I have just got a MBC with a vent (like in the photo) but I think I will need to bypass the control solenoid because it will not work properly unless I block off the vent hole. will see what happens.

Hi dvldoc, l have just bought a neo elgrand 60,000kms but l dont think it's power is right, l have read this very useful thread inside out and have just fitted a boost gauge to see if everything is good but on road test it runs at -10 to -20 until you lift off the gas then it will go to around zero and then l can hear some turbo whistle, my boost pipe arrangement is different to photo's on this thread, the pipe comes off the turbo servo to an electrical gadget by the airbox then to a can type thing on the engine then to some more electrical gadgets on the cyl head then to the servo's on the throttle body, do you know why my turbo pressure is low, any thoughts would be much appreciated.

[dvldoc]

Congratulations on your purchase, I love my Elgrand it might be 11 years old but man what a vehicle.

So you went with a neo, here's a few things. ZD30s boost at around 4psi at 100klm cruise speed, when you get into the throttle should jump up to around 10 to 12psi if your half throttle and if you put the hammer down you should be at around 16psi stock.

Number one your overboosting your hitting 20psi on a stock Neodiesel, It's one of a few things.

One. Blocked EGR valve

Bad MAF sensor

or Both


First thing you need to do is inspect your MAF sensor located in your air box assembly make sure it is clean of soot and oil residue.

Second you need to get the EGR system checked to see if it's blocked, It's most likely in this case, they get blocked very easy if you do not install a oil catch can on these engines. I would have the whole intake cleaned.

The biggest thing you can do to protect a ZD30 engine is get a manual boost controller, this will keep you from blowing a head gasket and fragging your turbo. These engines are famous for this, like Micheal Jackson Famous for this problem.

Take it easy and keep the boost under 16psi until you get these problems fixed, The reason for the damage it can cause is the high exhaust gas temps which will blow your head gasket or fry the turbo.

Get the boost controller first to keep the motor safe as the older ZD30's are basically ticking time bombs, the first clue is being low on power, that's the high exhaust gas temp and almost certainly a fouled MAF sensor.

When you get the manual boost controller, Oil catch can and do the EGR delete the ZD30 is actually a very good engine, but without these mods they can coast you 10000's of Pesos in repairs.

Also add 2T oil to your fuel, the injector pumps on these are not serviceable at most shops there so repair or replacement is going to be in the 100,000P range. You want it well lubricated with a little 2T oil in every tank full. The injection pump on these is what keeped me from getting one and sticking with the QD32ETI which uses the common Zextel Covac style pump.

Let us know what you find. If your not mechanically inclined I would take it to Bermmia diesel they are pretty familiar with the issues on these Elgrands. Speedlab i know has the manual boost controllers but you should be able to find it at almost any high performance shop like them or Autoplus.

Make sure you look over this as well.

http://users.on.net/~aschulze/ZD30/Z...t%20-%20BW.pdf

But you[SIZE=4] absolutely[/SIZE] have to get the manual boost controller to keep the engine from overboosting and blowing itself, A bad MAF sensor can send you up past 25psi in some cases and in the heat there the motor is as good as dead.


Feel free to ask any other questions.

Are you talking about this valve? on page 11?

Very good guide to install a manual boost controller on the ZD30 engine.

Manual Boost Controller

You only need a basic boost controller and not the in car needle valve. But this gives you a ideal of how to install one as these are different due to the VGT turbos. Elgrands should not be any different.

I have a question about my Nissan El Grand E50, I'm experiencing problems with its shifting ..since last week i notice a delayed in it`s shifting(overdrive off), and i have to pump my gas full throttle before it shifts...i want to know what is the cause of this delayed shifting?..

Good day El Grand owners,
We are having trouble with our nissan elgrand. May problema ng konti sa steering, kasi everytime na kumakabig sa kaliwa or kanan ng todo may tumutunog, sabi ng father ko parang may problema yata sa bushing nung steering. May alam po ba kayo na makukuhanan ng pamalit dun sa bushing? like other nissan vehicles baka may kapareha sya..

Medyo may problema din yung ElGrand namin sa coil spring kasi sumasayad yung gulong sa may tapaludo ng sasakyan, lalo na kapag at speed sya pababa ng baguio, biglang sasayad yung goma..

by the way, we have the 3.0 neo di engine, ZD30.
thank you and more power
