smoking patrol

its not ready to blow up. black smoke means there is more fuel than the amount of air,just finding the cause is the slow process

Yep different symptoms if it's about to "grenade"

I would be testing the injectors. Get it looked at sooner than later because a bad injector may be causing ring wear by allowing the oil to wash off the cylinder walls because the fuel is not being vapourised correctly.

black smoke from a diesel
Before doing any of the above check
-airfilter and intake
-turbo is actually boosting

after that it gets a little more complex
Dont assume that the halfwit apprentice Nissan put on it will have checked anything.

thanks for the stroppy reply, I would have said the same as you as an apprentice.
I'll concede it should have read "Nissan may have put on it"
But Im sure you are aware that it was a semi "tongue-in-cheek" generalisation of the the worst case scenario for this guy who appears to have been abandoned by Nissan. A vehicle just out of warranty and Nissan say they cant fix it? My point was dont assume that they have checked what they should have before spending money elsewhere to start from scratch again.

Yes I am a qualified tradesman.
Your customers shouldnt be talking straight to an apprentice, in theory. They are supposed to be under the direct supervision of a tradesman.
You talk to the tradesman and he tells the apprentice what to do then checks its done.
Have you ever had a bill from a dealer with a charge rate for an apprentice? Id wager not. So what do these apprentice do?
We know what they do, starting with the simpler jobs generally, except you get charged for a tradesman still.
Thats exactly what appentices are meant to do but due to a shortage of tradesmen the supervision often doesnt take place as it should.

Best watch the swearing also or you'll get "moderated"

Fisho, I agree with the sentiment but its the half wit supervisor that is at fault not the apprentice. Supervision is the key not the skills of the individual.

I have had my Patrol to Nissan for a 60000km service and back two days later to get it done properly as had found stuff not done. Funnily it never ran as well as when I picked it up the second time.

I suppose the difference is that some companies don't provide quality training. The places I've worked have given good training. Part of good training is also developing the apprentice's ability to be able to interact directly with customers. Depends on what industry you're in. I'm not in the car repair industry. I do know that some employers take on apprentices because they are cheap labour. Training apprentices is my 'raw nerve'.

I didn't realise I'd written anything disimilar to what I've seen on here ountless times before. My bad!

fisho thankyou for your reply,have checked all those things

hi rockape
thats exactly what i was eluding to - over fueling- this washes the oil of the cylinder walls and the rings and pistons will melt really quick
cheers

hi
followed a nissan smokep/trol in perth on tuesday couldn't see where i was going for black smoke bouching out it's tailpipe it was overfuelling as well and will blow up too

thankyou for your reply,its been to sevreal mechanics ,including nissan and a specialist near berrima none have improved it. Its air to fuel ratio is 17 to 1 which i am told is correct,turbo boost is normal,which sensor do you think it might be?

Can't believe the mechanics can't sort this for you. Diesel Engines aren't complicated.

Mate,
I don't know which sensor but if it had 17:1 air fuel ratio it would not smoke.

I still suspect a sensor as something is telling the ECU it needs more fuel.

If you haven't tried it already ask the question on the patrol forum, it maybe an intermittent problem.

again hope you can sort it out,
RA.

air to fuel ratio has been measured and confirmed at 17 to 1, injectors have been checked and are ok the vehicle has approx 90000ks only.

Bet mine smoked better than yours at Silverton Scrubby!

Scrubby what was the cause of your patrol smoking at silverton?
and i checked with nissan and am advised nissans have a similar valve for cold starts in fuel pump they have agreed to have another look at it this week.

thankyou for your reply tried that no difference

it blows smoke all the time the higher the load the more smoke,easily seen in rear view mirror,i towed a light capmer last weekend it has black soot across the front and down left hand side.when towing it is atrocious...Does anyone know what was the result of the patrol smoking at silverton????????

Fuel consumption is high approx 5 to 6 klm /litre around town NOT towing.

Seems like overfuelling as apparently everything checks out,the reply above about the toyota having a valve in the fuel pump is worth a thought,dont know if nissan has the same.

Thankyou for your replies.
