Major Problem- some advice appreciated

[ova50]

Apologies for the length of this.

Recently I started a thread about the Extended Nissan Warranty. In the thread I mentioned that my Patrol was at the dealer and had a couple of problems. It had lost power and was blowing excessive black smoke when the vehicle had warmed up. The Dealer replaced the EGR pipe as it was split and cleaned the egr. I was told by them the take it for a good run because it needs to reset itself.
Two days later I booked the vehicle back in, as it seemed to be getting worse not better. Got a call from them to say to they replaced the MAF sensor as some codes showed it was faulty, and its much better. Was again told to take it for a long run up the F3 (syd-newcastle) as it had carbon build up due to the spilt egr etc.

Half hour later I was back at the dealership, an told them I did not feel comfortable driving this up the freeway because it is billowing black smoke and is heaps worse and did not want to risk it. Eventually they said to come back in the morning. Picked it up today and was assured it was carbon built up and to take it for a run. I told them I will call them tomorrow when I get back from the run. My wife followed me home and the smoke is worse, my wifes words were "the smoke looks greasy if the sun hits it, and once you could faintly see the colours of the light spectrum.

So Im meant to take this for a long run (maybe a 150k round trip) (oh, the dealer has put this "take for long run" on the invoice)

Gets better, we have dinner tonight with guests, one of which works at the dealership & happened to work on my vehicle (dead set, guys). He says its carbon, and the CDRs do smoke, yer, but not like mine does, I say. Then tells me that Nissan wont do any more as they deemed it all ok, and that if they done, for example a compression test and found something major, it would depend on the vehicles service history whether it would be warranted. Whether this statement was from Nissan or the dealer, I dont know. ( I bought this second hand in October last year).

My vehicle is a 2010 3.0litre DX, has 95000ks and close to warranty expire. My wife and I have been sitting here discussing all the what ifs about this whole thing.

I anit no diesel guru but I dam sure this is over fuelling, dealer says no, and claims its carbon blowing out, and now its mentioned Nissan or the dealership wont do any more.
I should ad that I had this at another dealer ship in another state recently, had a bad fuel smell, the fuel rail or pipes were replaced, whether it is pure coincidence but the vehicle appeared to feel gutless on the odd occassion. A couple of times on the way home we did notice some smoke but was up hill and the van in tow.
AHhhhhhhhhhhhhhhhhh!
If anyone has some advice with our dilemma (apart from going balistic) We both would appreciate it.

[MudRunnerTD]

Don't rest. Don't let the warranty run out without an absolute outcome, good or bad you want Nissan to put it in writing that it is not their problem or fix your bloody car before the warrant expires.

Offer to swap cars with their service manager for a week and he can tell you there is nothing wrong with it.....

[jack]

Geez mate that's not good. Maybe worth taking it to a diesel mechanic for a second opinion, might give you an idea of what the issue actually is.

[macca86]

Normally the black smoke it over fueling normally caused by intercooler hoses split intercooler leaking or turbo vaccum hose split or off or blown turbo or maff fail. You should try a scan guage or get your boost checked

[ova50]

I have to say that I do not feel comfortable taking this for a long run tomorrow, in case something major happens, (eg, burn a hole through the piston) ,but the dealer said to and I will quote whats on the invioce I got from them today:
"Checked all air intake hoses & air filter, all ok. Will require to have long drive to further clear any residue of carbon build up"

My wife and I are currently on an around the country trip, and in Sydney for the xmas break and were planning to hit the road in a few weeks.
I would hate to see how much smoke it would blow towing our van, (van colour would probably be black before we got to Liverpool)

"

Maf was replaced yesterday (have invoice stating so). It says: " Ran diagnosis- found codes related to MAF sensor. Replaced sensor"
Only last week did I mention to my wife, I wonder if the turbo is crook.
I do have a scan gauge but is not yet installed, have been waiting for my youngest son to visit to give me and give me run down on it and set the dam thing up (I got lost on the first few pages on the instructions,lol and he lives 200ks from us)

[macca86]

Get it to another mechanic get the turbo checked it'll take them 2mins they check the imprella nut I think its called. Your egts will be going through the roof very bad for engine life

[the evil twin]

Photocopy everything,
Diarise every conversation, telephone call etc
Write a covering letter and attach photocopies and send to whichever is the choicest Consumer Advocate mob in your state so there is a file open.
In the covering letter make sure you put down your concerns and what you expect as a resolution.
CC to the dealership prncipal and Nissan Australia
This means that a pre-existing issue is documented and remained unresolved prior to warranty expiration

None of the above helps with the inconvenience if your engine drops its guts in the middle nowhere but will be worth it's weight in gold when your letter of demand for compensation and damages hits their desk

[threedogs]

Sounds like Mr Nissan up to their old tricks,
never give up ,never give up, never give up.

Would be a good oppurtunity to fit boost and EGT guage
to monitor the engine, this mod is pricless IMO.

[mudski]

If I were you I would be fitting that Scangauge ASAP. They are not that hard to work out. Fitting takes 2 minutes.

[ova50]

If I were you I would be fitting that Scangauge ASAP. They are not that hard to work out. Fitting takes 2 minutes.

Put the scan guage in this morning, I did not bother setting the fuel info for mileage/distance etc.
Is it ok to do this at a later stage, or should it be done now.??
Scrolling through the guage I have found the usual things like rpm, voltage etc. Found one that reads, no codes found (i assume this is an important one) plus heaps of others.

Any advice as to what I should be looking for as far as the readings etc on the guage??
Any info is appreciated (except if is stuffed, wont appreciate that,lol) Should mention my Patrol is an auto.

I was also having a look around the engine this morning (not that I have a clue what I am looking for).

However I happened to wiggle this hose (attachment) and it quite loose, could have removed it without undoing the clamp. I figured this should be tight so done it up, now secure. ( clearly Nissan saying they have checked all hoses etc is pure crap and will will be nailing them when I see them)

I went for a short run and the smoke is still there but I dont think it is quite as bad. (unless its my brain playing tricks on my eyes).

I have spent most of the day documenting the conversations, dates etc, that I have had with the dealer.
Still all up in the air at the moment. (damm, Im starting to miss my old 4b)

[Maxhead]

Don;t give up now mate, you've done the hard yards ...just wait and reap the benefits. Nissan will be responsible for any work needed and they WILL fix it ...they have to.
It might even pay to see the pollution people and get them to measure the output from exhaust......

Make sure they cover all your expenses associated with this issue..... You've been mucked around enough.

GOOD LUCK!!!

Don't worry about fuel stuff yet. You can set that up any time.

Just a couple of quick things to set up are the units it displays, ie miles v klm etc, the size of the engine and type of fuel (DIESELa). Follow the instructions in the booklet and set it up for klm and ltr, temp I set to Celsius, for Manifold Pressure set it to BST not MAP, pressure units to PSI.

Select what readouts you want showing. For now I'd go with Boost and Temp and any other 2 you like.

Ooops clicked the wrong button!

Factory boost readings on my car were a steady 16-16.5 when I planted my foot with a momentary spike to around 18, the Scangauge might not pick up the spike as it drops in less than a second, around town boost rarely gets to more than 15 and with a light touch on the throttle to maintain 60-70kph it sits around the 10-12 mark or less. So if your readings are similar to those boost, is good. Temp is high 80s to a max of 91c so far for normal driving, even on 35+ days.

I don't know if you have EGT gauge but my temps are around 250-300c normal driving around, 400 or so pushing it up hills, I haven't seen it get to 500 yet.

Good luck mate, hope this helps.

[Cuppa]

Sounds like Mr Nissan up to their old tricks,


I wish you well in getting the problem sorted asap Ova50, & the following comment will be of absolutely no help to you, but nevertheless I can't help myself from making it.
The stories that abound about Nissan doing what they can to avoid their warranty responsibilities seem nothing less than shonky to me, I would never buy a new Nissan, despite being the owner of two Nissan vehicles. Their spares backup for my '89 model bus is also pathetic. (Pay first, see if it's available ex Japan, wait a couple of months if it is & pay the price based on the parts equivalent weight in gold! I really wonder how they stay in business with such a crap reputation, even though the vehicles they build are on the whole as good as any other & can only come to the conclusion that it is their lower purchase price (than Toyota) that keeps them in the market. It's the lack of 'How can we help' attitude that really pisses me off. Ova50's story is nothing new unfortunately.

[threedogs]

Just wondering if you have a chip in your 4x4.??????????
Change those child clamps for constant pressure clamps
a bit more pricey but well worth it around $8-$11 depending on size

I agree with the others who have stated about documenting everything.

You say that you were told that it had carbon build up. What has been done about that?

[mudski]

Ova. You say you found a lose clamp. Take the cover off the engine and check them ALL yourself. Check for any splits in the hoses too.
Without re-reading the thread. Has the intercooler been checked for leaks?

[ova50]

To Lonicus: Thanks for info on the scan guage. Is your vehicle an auto??. I assume that some readings would vary depending on whether it is an auto or manual.

EGT gauge, dont have one.

Threedogs: Apparently no chip has been fitted, and agree with you about those stupid clips. I am planing to replace as many as I can.

Ben-e-boy: With the alledged carbon build up. The dealer says it needs to be taken for a long run and by doing this it should blow out & clear the built up carbon, claims the carbon build up would have happened because of the split egr pipe. I will ad, that statement does not sit well with me. The egr was supposedly removed and clean. Surely there is only so many places where you may get carbon build up. (maybe when Im at the dealer again, maybe I will be told its in the boot or glove box )

Mudski Im am begining to think that they havent checked as much as they claim to. Hell, I know stuff all about diesels & turbos, yet I found a loose hose and clamp and in plain view. This alone puts a big question mark over the dealers quality of workmanship, service and honesty.

They may or may not have checked the intercooler for leaks, they have not mentioned the intercooler.
I will take off the top cowling on the weekend and check as many hoses & clamps as I can.

Can I check the intercooler for leaks myself and what is involved, is there any particular area that is a common place where a leak might be or happen.??

I have to use the vehicle tomorrow morning and will be travelling about 60ks, hopefully I will be able to check the numbers on the scan guage and compare with what Lonicus has supplied. Then check as many hoses I can.

If I think the smoke has reduced, (and since tightening the clamp) I am planning on taking it for a run up the coast on Sunday.

(apologies for any spelling errors guys, been a long day.) Damm that took a long time to type.

[Lonicus]

Yes mate, mine is an auto so readings should be pretty much the same.

[ova50]

Yes mate, mine is an auto so readings should be pretty much the same.

Thanks, that will give me a good starting point. I forgot to mention that when I plugged the guage in and was scrolling through some of the things may have been detected by the guage or could these have been pre set. ones I noticed was fuel already showed diesel, Engine already showed 3.0litre. and remember seeing a bst displayed and not map.

[Lonicus]

The gauge does pick up a few things when plugged in, such as engine size, and other presets may be different to what is in the book. I'd say software/firmware is updated more regularly than the paperwork.

Good luck with the drive mate.

Interestingly, I was searching the net this morning for diesel guys around my area and came across a link to exploreoz. A guy had posted, asking for a diesel mech in or near his area. Wrote, that he is fed up with his local Nissan dealer damaging his Pathfinder. (his area is the same as where I am and there is only one Nissan dealer in our area). Thats a concern!!!
Looks like Im not the only one that has had trouble with this dealer, and bet there are plenty of others.
(apologies for any spelling errors guys, been a long day.) Damm that took a long time to type.


There isnt many places that carbon can build up with an EGR I agree, just the intake port and valve. Have you ever tried breathing through a straw?
If there is carbon buildup around the intake valve your motor will be trying to breath through a straw. The lack of air explains the lack of power and black smoke.

A long drive might help a little bit, You should remove the intake manifold and inspect the port and valve, if it is built up around there you need to remove the head get it cleaned

[mudski]

When you remove the engine cover, leaks can sometimes be easy to spot. Given signs are black oil deposits on the core, usually where the tanks are joined to the core. If you see any oil, even a small amount it will be leaking. Plus, look under the intercooler on top of the engine too. As if the cooler is leaking on the underside, the oil will drip onto the top of the engine. Might be easier to take the cooler right off to inspect properly. Its not hard to do. A couple of hose clamps to undo, a sensor clip or two, and then the mounting bolts. Its a ten minute job to take off.
You can get them pressure tested too. I saw a chap, block one end of his IC, cap the other with an air fitting on it, and then filled the IC with smoke and then blew compressed air into it and saw the smoke leaking out of a tiny pin hole. Or cap both ends, one end have a fitting on it so compressed air can be pumped into it, drop the IC into water and fully submerge it and then pump air into it. See bubbles? Its leaking. You can even use a bike pump as it doesn't need a lot of pressure to test it.

[happygu]

I occasionally get a little black smoke out of the CRD, but it is definitely not bellowing smoke all the time.

I would say that if you have checked all the obvious stuff, and can't find anything wrong, then your only option is to do the 'long drive' as the dealer suggested and see what happens.

It will be the only way you can get it back to them to look at it, and I don't think that you will do much damage in 200 klms.

[ova50]

Today:
Went for a short run and, that then became a long run. Clocked up over 350ks.
I had 4 things displayed on the Scan gauge: LPH, Boost, Temp and RPM. Also took some readings using the MAP instead of the Boost.
We wrote down all the readings we got, depending on how we drove. I will post them once I get them together in an order to read.
Thanks guys

[ova50]

First up, Its been raining in Syd, so didnt have a chance to remove the top cover off the engine to check other hoses. However I did find this one.
Had a spilt in it about an inch from the end, has gone brittle, probably through heat. I cut the piece out, and re-attached, till its replaced. Then we decided to head of up the coast with the scan guage set. First I noticed that the smoke didnt appear to be as noticeable, particualry under acceleration.

Having now found two hoses that were loose or damaged, it put a huge question mark over the quality of workmanship from the dealer. How the hell can they say that they have checked all the hoses.
This doesnt sit well with me at all, and Im far from happy about it. Im not sure at this stage what my next move should be.
Should I go back to the shonky dealer or contact Nissan direct??.
I have lost all confidence with this dealer and do not trust them, period.

About to post the Scan Guage figures.

We gave the Patrol heaps, put it through its paces big time.

[ova50]

Temp: readings maintained between 88c to 90c

1. Boost: Drove to speeds listed and held throttle, then slight pedal to maintain the speed. PSI
60kph = 5.5 maintain speed = 6.0
70kph = 5.5 maintain speed = 8.5
80kph = 3.1 maintain speed = 8.1
100kph = 5.0 maintain speed =10.0

Next is acceleration from 0 to 60kph using different throttle pedal positions.
1/4 throttle to 60kph = 12.4
1/2 throttle to 60kph = 14.4
Full throttle to 60kph = 14.6.
Driving on a flat road.

2. LPH readings.
Coasting down hill and no throttle = 0
Next was cruising at following speeds
60kph = 10.7
80kph = 13.5
100kph= 14.9
LPH: The following is acceleration from 0 to 60kph using different throttle pedal positions.
1/4 throttle = 23.2
1/2 throttle = 34.1
Full throttle =39.4

Also thought I would check acceleration times, with full throttle.
0 to 60kph = 8.52 seconds
0 to 80kph = 12.36 seconds
0 to 100kph = 20.57 seconds

Map readings
Idle = 14.4
60kph = 6.5 to 7.1
60kph firm acceleration = 16.9
80kph = 8.2 to 9.5
80kph firm acceleration = 18.2

So guys, how do they compare or is there something odd???.

Clocked up 355.2 used 48.65 litres = 13.69 L/100
I thought this was good considering the way we drove it.

Vehicle smoke was a lot less and we noticed as soon as we left home. Do notice that if sitting at a set of lights , and then take off its get that puff of black. Under firm acceleration up a slight hill, I can notice a little doing about 40 to 50kph and vehicle has changed into second gear. Sitting on around 100 -110 up a steep hill, (Mooney Bridge) and kicking back while still accelerating, is more noticeable.

Both of us say it is nothing like it was.
Not certain how it will be with our caravan hooked up to it.

I had similar problem with my 2007 model 3 litre,heavy over smoking (black soot all over the camper i towed) it took several visits to nissan dealership before they agreed to fix under the extended warrenty,turned out they replaced all injectors and associated plumbing,result no more black smoke,dont give up it is a genuine warrenty claim....My vehicle had about 100000klm and nissan advised that the injectors had been replaced by the original owner...

[Lonicus]

Hey Ova,

Boost readings look pretty good, even a smidge lower than mine so shouldn't be an overboost problem.

Your LPH readings again are pretty much guesswork by the Scangauge at the moment. You will be able to refine the rates and get more accurate readings once you have run through a couple of tank refills and made the adjustments in the gauge. They are pretty close to my figures though before adjusting the gauge.

The 13.9LPH usage looks pretty good, plenty of people on here have stated they get a lot worse.

0-100 times I'm no help with sorry mate. After my last car I feel like Fred Flintstone in the 'Trol and I'm just glad it gets to 100+ :)

The smoke situation sounds a lot better. I get a puff when I give the peddle a quick kick and my wife was following me one day and said it blows a bit on gear changes. It's an auto so I assume she saw puffs as kicked up or when I gave it a bit of right foot.

Hopefully someone on here might know of a decent mechanic in your present location. I'd be getting someone trustworthy to go over it, especially the hoses, fixing what needs it, then present the list and invoice to the dealership with a copy to Mr Nissan, highlighting the two hoses you've found yourself that had problems.

Things definitely sound a lot better though mate. A good check of the hoses, replace the ones that need it and maybe throw it on a dyno to get it purring!

Good luck!!

That's prob not a bad idea get a 2nd opinion if you can get some one (real mechanic) to look at it quickly i case there is something obvious that the apprentices at Nissan can't see then get nissan to fix it and flip them the bill.but sounds like Nissan has just had your car in the car park the whole time you had it there, these hoses you have found yourself should have been picked up I would be blasting them over it!

[ova50]

Thanks to all, and to Lonicus for providing your vehicle details. It has been a huge help.
Also Evil Twin for sending me some gauge readings. Thanks.
Now for the next step, I have to make a decision whether to take it to a independent diesel mech and have them go over it, or go back to the dealer again.
Will have to have a good think about this, so as not to make the wrong decision.

[Lonicus]

Glad to be what help I could mate. I hope you get it sorted!

[mudski]

I see no reason to go back to the dealer other than to jam the piece of broken hose up the mechanics proverbial. Theres definitely an over fueling issue here but to exactly where? You need to ge that cover off and really check everything yourself. I just replaced all my rubber vac hoses with silicone...Looks a lot better too...

[ova50]

Hoping to get some good weather, cannot get the vehicle under any cover where I am, so weather is the problem.
Fingers crossed that it clears up.
Thanks again.

Lol I know how you feel mate, apparently I'm a Patrol Guru ROFL! Guru at asking questions is about it :)

[PMC]

Geez mate that's not good. Maybe worth taking it to a diesel mechanic for a second opinion, might give you an idea of what the issue actually is.

G'day ova50,

I agree whole heartily with Apollofish, get a second opinion. Everything in life is about quality research to help achieve a positive outcome! On getting a second opinion, I would conduct research on who is the best diesel tuner in your area and go to them. You want someone who lives and breaths 3lt Patrol's. I know Berrima Diesel are fantastic at tuning Nissan Patrols. They are a about 100ks South of Sydney. The following are there contact details;

Phone: +61 2 4877 1256
Fax: +61 2 4877 1239
Email: info@berrimadiesel.com
Address: 3483 Old Hume HWY Berrima NSW Australia 2577
Opening Hour: Monday-Friday 8:00AM-5:00PM(AEST

PS, Personally, i think you have an over-fueling issue, black smoke = un-burnt diesel fuel! "nissnannewby", if you are on line, could you help shed some of your valuable diesel knowledge here mate!

Regards,

RLI

[bobryaner]

just reading the post so whats the outcome now is the car sorted out and have nissan honoured the warranty

[ova50]

just reading the post so whats the outcome now is the car sorted out and have nissan honoured the warranty

Not yet resolved, have a video of the smoke and will post updates as they become available.
Thanks

[threedogs]

0-100k sounds good somewhere here someone did time trials and 19 secs to 20 is good.
pretty sure the CR love being driven like they're stolen. Ask to speak to who ever worked on your patrol
and find out how he/she checked your hoses. Vacuum hose is 20c a metre just replace the lot yourself.
find yourself a good diesel mechanic ,one who'll keep your history, someone here may know someone for you

[BigRAWesty]

Has the smoke issue just appeared, or has it been gradually increasing?
I'm with the other boys but injectors usually just stuff up, there a gradual thing.
Did you or anyone do anything to the fuel pump or fuel system previous to this?
Has the fuel return line got a blockage??

Has the fuel return line got a blockage??

It had a fuel pipe replaced in Queensland, & fan belt tensioner (warranty) had fuel leaking from the pipe on number 3 injector. After this was done the vehicle sometimes appeared to be down on power (coincidence ???)
Didnt use the vehicle much after it was at the dealer (had access to another car) It wasnt until we were on our way to Sydney that we started noticing the smoke. Thus the visit to the Sydney dealer, who then says they found the egr pipe was split almost through its entire width, then the story goes on from there.

Today, I had to go somewhere, still smoking and both the wife & I are sure its getting worse. Also a couple of times when accelerating from a stop and using about 1/3rd throttle the vehicle would not want to pick up speed, even depressing the throttle to half way the vehicle would only be doing about 50kph, then would start to pickup. When this happens its not until the revs get to about 2500 plus would it accelerate.

I have been trying to find a local diesel mech, I think I have found one and are going to see him on Monday. I was lent a Gopro camera to video the smoke, the camera has difficulty picking up the smoke, on video where the smoke is the video seems to pixelate, it can be seen but not clearly. I had the Gopro attached to the rear of the Patrol and also placed in on the bonnet of another vehicle to film from the rear. Also used a cheap car cam, mounted in another vehicle that followed the patrol, the cheap camera filmed the smoke much better than the gopro and can be clearly seen.(although the quality of video poor) I sent this video to another member to view.

Carbon build up, no way.

Has the turbo been checked to see if that's gone. Has the cooler and hoses been checked by you or another mechanic or is the throttle position sensor been checked or any other codes thrown into the scan guage.

Thanks Lonicus, for uploading them.

Guys, please disregard the date stamp on the videos, as it was not set correctly.
As I stated previously, the Gopro camera does not seem to film the smoke (even though it is quite visible), yet the cheap car cam with its poor quality does film the smoke ( I cant explain this)
First video shows smoke from around the 17 second mark. & smoke pixelates on the video.
Speed of vehicle is between 40 to 50kph, up hill and not heavy throttle.

Ever thought of blocking the EGR and fitting NADS to your 4x4 ??????????????
