• so the details: Yesterday i did a mild tune up on my 06 Xtrail. Things i have done often with no issues after the fact.
• I removed two spark plugs to check their condition. Reinstalled and seated/snugged up the threads.
• I sprayed my mass airflow sensor with the correct cleaner, let it dry for 30 minutes, reinstall.
• I sprayed and wiped inside the throttle body with the proper throttle cleaner spray.
• I removed my air cleaner filter box , blew/vacuumed inside it, reinstalled the ar filter.
• I removed my PVC valve. Checked to make sure not clogged. ( i replaced it with a new one only 3 years ago) . Reinstalled it.
• I made sure every hose i touched, every bolt i removed, etc, was reinstalled. I only just checked my engine oil level ( clean/good ), checked my tranny fluid condition ( clean/plenty). I had put in a 500 ml bottle of

Gumout Regane High Mileage Fuel System Cleaner
...was almost $14 cnd at the Walmart. I admit, i put the entire bottle of fluid in a 1/4 tank. But i have done this with 1/4, 1/2 tanks and never ever any issues. Anyways, after my simple tuneup, i went to start the car and it started up great, no problem. I shut it off, restarted it, revved it 30 seconds, let it idle. Shut it off, turned it on...let idle...shut it off. The engine purred.

• This morning i decide to go start my truck and drive to get a lotto ticket plus $15 of mid grade gasoline. ....White/blue smoke from the tailpipe.
• I figure maybe it's the fuel injector cleaner, i drive it for 5 minutes. No change, warmer the engine, the more smoke. People in traffic behind me where trying to avoid my big clouds of smoke. I went to the gas station ( a ten minute drive) and go to put in $15 of mid grade. Start the truck, sae smoke. Drove for 20 minutes to see if smoke dissipates. Same crappy smoke. Especially when i step on the throttle.
• I parked by a high school near my house and let the truck idle. During idling, i really do not notice any smoke. ( BY the way..i picked the school side street as there were no kids around, raining/windy out....the smoke got blown out into the empty school field so nobody got bothered by it.) With my engine running, i pop open my hood. Engine sounds normal, no smoke or funny smells from my motor. I pull out the dipsticks to the oil and transmission and everything looked normal. Close the hood, get into my truck, rev it a little...white/blueish smoke. I can even smell a slight metal ''aftertaste'' odor in that smoke. And it was just billowing out. Oh...should mention...first 10 minutes of driving, i can feel a lack of acceleration from 50 klm per hour and up. After 20-25 minutes of driving, the pickup felt a bit better, but i would not trust it on the freeway to merge/accelerate.
• Finally, there are no dash lights lit up. -

-- Is it possible...a coincidence as i was commenting about maybe needing a new cat converter ''one day''....that it might just be my cat converter?? -
Or did i do something stupid , something i overlooked?? Too rainy wet outside to go tinker under my hood....i go start it up and take for a drive about 8pm ...long after rush hour is over so i don't piss off other drivers in traffic with the smoke or attract the attention of the police. >>>$$$$ ticket.

Gotta be something simple since you just worked on it. Does the smoke smell oily or chemical? If it smells oily then chances are it's your PCV or plumbing, if it smells chemical then your injector cleaner may have compromised an injector and now it's leaking.

ummm...i would say it smells chemical. Like...a metallic smell in the smoke. Trying to think of something similar. If you left a frying pan on your hot stove element ( no oil in the pan, empty pan) and you smell the pan itself burning.

• Odd tho if it is related to the fuel injector cleaner. Over the past 10 years, i have used a variety of fuel cleaners. Poured straight into my gas tank. Never a problem, old or well used vehicles.
• even seen a few youtube vids where a mechanic suggest to pour a liter or two of Thinner into the gas tank ( with 3/4 full tank ) as that will clean the injectors. I did that over 1.5 years ago in my Xtrail, no issues, ran fine.

i just googled and found this :
What color smoke is a blown head gasket?
The most common sign of a blown head gasket is exhaust smoke. White smoke indicates that your car is burning coolant that is leaking into the cylinders. A similar problem is indicated by blue exhaust smoke, though this is a sign of oil leaking from the gasket.Apr. 7, 2018
--- i'm pretty sure i did not disturb anything to cause oil or coolant to leak into the wrong places. The things i mentioned previously regarding the tune up, done often on my xtrail, the matrix, and other cars i've owned. Never had any issues. I mean, if i screwed up, i be glad to admit and rectify it. Otherwise i need to drive it to a local mechanic and hope i don't get gouged on whatever repair is needed.

Yep, that's an injector, probably stuck wide open. There can be too much of a good thing with fuel system chemicals. It isn't a head gasket, that's white but you'd smell anti-freeze. You need to identify and fix the bad injector quickly or it will overheat and melt your catalyst. The simplest way is to pull plugs about 5 minutes after you kill the engine. The leaker will flood the cylinder and you'll be able to see it down the spark plug hole.

IF it is an injector....i will need to have it replaced at the local garage. Is that an expensive part/labour repair on an 06 Xtrail? mind you, i live in Canada....we tend to pay more for everything all the time compared to you in the USA. .....but what is your usa guesstimate?

Dunno, I don't think we have your particular setup here in the 'States, but as I recall the QR20 is set up similar to the QR25 in the Rogue. That would be 3.5~4.0 hours labor, and since the fuel rail has to come loose, there's very little point in replacing one injector, just get a set of reputable remans and do all of them.

 

[tonyvancity]

is it possible for a mechanical shop to ''unstick'' the injector? or will it need replacement? I again googled a generic fuel injector cost and it said $300-500 for one injector . Some say to replace all 4 if high mileage, others say to just replace the bad injector. This could potentially be a big, big expense, one injector or all four.

the 2.5L Xtrail engine is the same as the 2006 Altima 2.5L engine

 

[VStar650CL]

Way easier then, 2.0~2.5 hours.

 

[VStar650CL]

If you can't get them cheap then just one is okay. It's one of two things, either the injector is stuck wide open or a seal is blown. You can't do anything about the latter, but you can try very carefully tap-tapping the injector body with a tack hammer if it's stuck, sometimes they'll free up. If you can get me a part number for the injectors I can try to source remans here in the 'States and see if anyone will ship to Vancouver.

Okay, from what I can tell (not infallible), your original injectors should be 16600-2Y905. Those cross-ref to a 16600-2Y90A and 16600-2Y915. If so, these will fit, and they do ship to Canada:

thanks for all the help/info guys. I will wait till tomorrow morning and with better daylight, flashlight etc, i can retrace my steps and see if i made a silly mistake and maybe an easy fix. If not, i may have no choice but to drive the 5 minutes to a nearby mechanical shop who fixed my Xtrail electrical issue last Spring.
- I know the shop manager/owner. We worked together at an automotive shop for about a year going back 7-8 years ago. He cut me a deal on my first visit. Maybe he be sympathetic and give me a bit of a price break. ( so I was hired as the in house autoglass technician/shop helper...he was the 3rd year apprentice mechanic. )

If he does a lot of Nissan he might well have some good used injectors laying around. Those p/n's are pretty popular.

assuming they are in fact injectors that i need. Maybe he put on the scanner or do his mechanic magic and discover something else altogether. -
- pretty sure it's not a banana in the tailpipe. ( yup, i actually looked incase some dick was playing a prank on me)

Too funny! From what you said about the smell and the people behind you, I'd be pretty sure that's your issue. Nothing else smells quite like an injector cloud on a catalyst vehicle, it's uniquely chemical and very acrid. Oil and anti-freeze are "just" stinky, half-burned fuel is choking.

I wrote a thread on replacing the injectors, and the confusion surrounding the proper type including my communication with GB Remanufacturing. The Hitachi new ones from RockAuto are your best bet. Replacing them was a pain in the ass job, and in my case did not make much difference. I thought they must be clogged and worn after 220,000 KM, but they were actually still good and none of the O rings were leaking. I replaced my intake manifold gasket so did the injectors at the same time. You can probably get away with just removing half of it to be able to get the fuel rail and remove the injectors. Good luck. I hope it's nothing more major.

True, injectors are probably the rarest issue on Nissans in general. For the most part they're all very reliable and we rarely need to replace any, even on very old rides. Tony is just unlucky, or maybe the cleaner he used swelled and popped a seal. I've never used that particular brand so I can't speak for it.
