Q50/Q60 VR30DDTT Injector Failure
Вставка
- Опубліковано 26 лис 2019
- A quick sped up video of me taking the intake manifold and other components to get to the injector rail. This injector failed while using E85. Is it safe to say E85 is the culprit? Not exactly. We've seen these failed on stock cars and tuned cars but, the issue becomes more frequent when running ethanol. Even running an extra in-line fuel filter we're still seeing these issues across the platofrm. Shoutout to Austin INFINITI for overnight shipping the injector. Enjoy...

This has been fixed and the car is running back to normal. More info. to follow!
Enthusiast POV hello I have a q50 red sport when 4/5 hours go by without starting the engine the low fuel pressure is hard to turn on but if I turn on and off the switch 2 or 3 times before starting the engine, then it turns on perfect and change fuel regulator and pump and nothing
Fuel pressure sensor
Enthusiast POV how it looks or where it is located
Damn dude All the for 1 I would’ve replaced all of them with those aftermarket ones you mentioned to reduce the chances of having to do this again
Aftermarket ones aren’t even out yet.
Bro I can’t thank you enough for all the amazing informational content you have posted and shared with VQ\VR community!! Legit its been amazing watching you on your journey during this build, I know this issue sucks but this is only a small obstacle in the road to building your dream car. Dreams are driven fam, Because of all your hard work it inspired me to purchase an 2019 Q50 i-line REDSPORT after my G37 was in a car accident an written off this year and I plan on following your footsteps in building my dream car. Keep your head up fam, the obstacle is always the way, I look forward to seeing your new HP spec once those Nostrum Injectors are installed.
Haha if i even install them 😂
But thank you for the support man it means a lot 🙌🏽
My kind of video!!! Great stuff!
Man you saved a grip doing this your self. Perfect time to upgrade!
Thanks man. I think for the price they will be, on stock turbos it’s not a good investment to upgrade injectors. But I did save quite a bit doing this lol
Know all to much about these stock injectors 😂. Another great vid man.
Thanks man
thank you for venturing into this level of disassembly on your own , i need to buy a cheap honda or something and tear it apart so i can start doing some level of work like this myself lol.. i plan on getting a q60 redsport in about 14 months but it willl be under warranty so dealership fixes although i will do bolt ons :) but your braveness is appreciated for this platform.
Thank you sir
My 2016 Q50 I just bought I think has the same problem. It's in the shop now. After seeing what it takes to get to the injectors, I'm understanding why its taking so long to get it back. Thanks for showing us what's involved.
So got the Q back. They replaced all of bank 2's injectors and the fuel rail. I'm back on the road🙂
I had the same injector on the same cylinder fail and never put in e-85. Feel your pain, at least mine was covered under warranty
Also that was a great video
i was going to run E85 in my Q50 my tuner didn't recommend it right now as he has seen this problem over and over again with the injectors failing on E85.. I'm going to run 100 octane for now until new injectors are on the Market to hopefully take care of this issue
The next step for my q50 is e85 but the ams injectors are very expensive and I saw a video with someone using deatschwerks Ford F-150 injectors that flow 1700cc do you think that would be reliable or safe?
Curious on what cc injectors are the stock ones? When running E85 on my Evo, I had to upgrade the injectors to 1000cc to be safe. In the Evo/subie community it's a must to upgrade that and also run one step colder sparks as well as fuel pump upgrade.
DI injectors are a little different than PI
Hey bud! Been watching your videos for years and finally pulled the trigger on Q60. I know this an old thread but asking if you recommend fuel injector cleaner in the gas tank or not? Can’t find anything certain on the website. I put the addW1 catch can in at 17k. Just got the full stage 3 from AMS. Not E85 yet. Your response would be much appreciated.
Hey man thanks for the video! So I have everything loose and I'm at the part where your camera died when taking out the fuel bar. How did you get it out mine seems to be hitting the opposite fuel bar and I can't get it out. Am I suppose to take the other one off too?
No specialty tools required for removing injectors? Or refitting the teflon ring?
Hey enthusiast when your run an E 85 try putting the Lucas upper Cylinder cleaner and lubricant that should help stop the injectors from getting stuck
It should ! I’ll try it
I have the exact same codes as you but it’s my cylinder 1 misfiring. Car also sounds cammed but no rod knock. Could this be injectors
hello I have a q50 red sport when 4/5 hours go by without starting the engine the low fuel pressure is hard to turn on but if I turn on and off the switch 2 or 3 times before starting the engine, then it turns on perfect and change fuel regulator and pump and nothing
What were the symptoms mines giving me a misfire on cylinder 2 and shaking n smelling like gas inside the car
My fuel rails have been leaking gas did they have a rubber seal ?
By any chance, did you look at the valves to see if they’re all carbon up because I know you’re running a catch can just curious to see if it works great video
😂😂bro same thing happen to me last night bro and you could smell the gas from your exhaust
I have a P0300 any ideas on what that might be
just happened to me but car doesn’t even start have to take it too dealership to reboot the system, my injector went bad then the spark plug and the ignition coil aswell
Do you or anybody in the chat recommend using fuel injector cleaner if so which one
I’m trying to fix my P0183 code & I don’t we don’t have a fuel filter
I hope that I don't run into any problems as I'm getting tuned in17 days. Just sticking with the 100hp plus tune, heat exchanger and calling it a day. Car is already fast with 300hp at the wheels.
Cleansed by the Blood should get Downpipes at least too
@@aa_fredo We'll see what the numbers look like with just the tune. Interested to see what the car makes with just the tune. That way can get an idea of what catted downpipes will actually provide. Think I've heard some discussions that higher flowing down pipes can lead to turbo issues on this car. Also I don't want to change and or/increase the exhaust sound level. Love and enjoy the car just like it is but with some more juice to the rear wheels.
Cleansed by the Blood you’ll probably spend more money if you do eventually go Downpipes the way you’re doing it. Yeah there is discussions that FULL Downpipes will lead to issues down the line but with just lower Downpipes you should be fine. it really is a choke point for the 3.0t
Cleansed by the Blood you could also just buy JB4 , a lot cheaper and if you’re not adding supporting mods to the tune, probably almost the same numbers. If you’re under warranty and want to keep it, even better to do that
@@aa_fredo is JB4 likely to add 110 plus hp? If i fail to gain that or higher at the wheel i'll be highly disappointed. I'll be making a video and showing stock dyno hp and then tuned hp plus other important parameters to document heat exchanger performance from back to back pulls. I've worked up a deal they want some more Infiniti exposure. Ecutek tune lic 450.00 and dyno tune session 400.00. JB4 with bluetooth like $600.
I'm counting on no problems from keeping the car close to a stock Red Sport. It's when you start doing the ohter things that lead to issues. At least that's what I'm telling myself.
Ive tuned other turbo cars and kept things mild and had no issues. One good aspect is the shop happens to be 5 miles from my house. Issues arise and need to swap back to stock tune they have me covered. I blow the motor up or tear up the turbos and claim warranty then possible issue as they could check ecu history. For casual fun and super random racing on the street ultra low likely hood of major failure.
Off topic from the injector issue but I heard if you run full downpipes they can cause your turbos to over spin due to no back pressure. What do you think about this?
Never ran full downpipes to confirm this being a thing.
Have the same car with pretty much the same mods, thought I was one of the lucky ones but I finally lost an injector yesterday. So I was looking for new ones and found out ams is finally selling the upgraded ones so I ordered those along with new rails for a pretty penny. But reading their disclaimer, they state it’s metal partials from possibly the fuel rail causing the problem on the stock ones and could potentially screw the new ones up too.
It just seems everyone is having problems when going e85. I guess it’s the added pressure. I hope this will be the end of my fuel problems. I have spent a lot of money on this fuel system.
5k almost when it’s all said and done if you install yourself to run E85 safely on the VR30. Idk bro, this ain’t a GTR.
Did you inspect the inside of your engine?
With e85 I bet your pistons were super clean.
Yes I did. Valves were clean and everything was in really good condition!
@@EnthusiastPOV do you credit the catch can or sn plus oil... cause you didn't always have a catch can... so I'd assume you would see some gunk on the back of the valves by now.
@@KayDroTechnologies His engine is relatively new (was replaced under warranty), so I don't expect he has many carbon deposits.
@@aeroman5239 forgot about that... I'm always trying to gather data points...
My new engine has 12k miles on it that could be also but i always take very good measure to make sure it’s all clean and running right. I’d say the catch can has done a wonderful job thus far
So it’s unsafe to run a e blend with 91 to make E-30 ? Even with a flex fuel kit , in-line filter , and lpfp ?
You can mix e85 with any kind of octane to raise the content specially 91 since it’s always much less potent than 93.
Yea I’m in Cali bro ! Can I run an E85 mix with just a lpfp ? And just manually test the E content and follow the app mixture ? Or you recommend getting the whole flex fuel kit to be safe ?
Does powertrain warranty cover this ?
When it failed did ur car go into limbo mood?
Video made me a bit dizzy lol, but it’s very straight forward. How many hours to do?
JFYI, I slowed it down a tad as was hurting my head. slowing it down helped, turned volume way down. For future reference Go to the little wheel looking icon right side bottom corner > settings > playback speed 0.75.
Hahaha sorry guys this was 300x speed for about 45 minutes of work. Next time I’ll do 200.
Enthusiast POV lol no worries bro thnx
Cleansed by the Blood good to know thnx bro lol
Is it true that once you put down pipe and tune q60/q50 the transmissions go out? That’s the only think holding me back from getting a q60.
Not true lol
Enthusiast POV didn’t you replace your transmission a couple times? Might be getting you confused with other Q60 owner
Andres Garcia you definitely got me confused...
Ok cool! I wanna do downpipe, cut outs, intake and tune and just daily it. Any suggestions I’m going to get the normal Q60 AWD non S.
Completely off subject, but what blend of oil do you use?
5w30
Yea my cylinder 2 is misfiring and the tailpipe smells like raw gas. Running rough about to see what it is.
You ever figure it out
I'm dizzy now. LOL! Great job man your brave. I was mainly watching this to see if it is possible to peel back both intercoolers without disconnecting any lines. Planning on cleaning my throttle bodies in place. Looks like you did peel them back but the vid was so fast I'm not sure if you disconnected any line which would call for bleeding the system. Do you have video on throttle body cleaning maybe?
Hey man, I’m a little late but you can peel back the “squid” without bleeding anything !
As far as the throttle bodies, I stay away from those. I see the horror stories every day about cleaning those lol.
Whats the firing order
Can u put GTR injectors on the q60?
No. The Q60 is direct injected. They’re different style injectors
how many miles when this injector failed?
23k
@@EnthusiastPOV like and sub'd
Also what kind of injectors are you going to put in it and upgrade or what
Lol stock injector went back in. Upgraded injectors aren’t on that market yet
Enthusiast POV. Bummer man I figured they would have something out by now I don’t have a Q 60 yet I’m going to get one in late 2020 I hope hey I appreciate your time keep up the good videos and by the way my name is Brian nice to meet you
Nice to meet you Brian haha. Yeah man it comes with the times i guess. We should see more options soon
@@EnthusiastPOV Glad you got it fixed can’t wait for those Nostrum injectors and when your install/review video comes out. Flex fuel is where I want to go as well but not until the full support is out. I give you so much credit for being the brave trailblazer. As I’ve said before so happy Japan is finally using this motor it only means more and more platform support.
What code did it throw you I have a p256 3 code
Same code changed the turbo and nothing it worked for a bit and now only turns on on cold start and turns off after one block..
Did you find out what it was???
I was toying with the idea of getting the new 400z but after seeing the mess of an engine that Nissan made I'll pass.
You’re onto something 😂
No warranty?
Why bother it’s a modified car lol. $160 part rather do it myself and learn a thing or two. Pay to play.
@@EnthusiastPOV I had mine fail and I was lucky they covered me. I just made the engine bay look stock except for the intakes. They did ask if I knew anything about my ecu being flashed 16 times including the day before I took it in and I just said eeeeeeehhhhhhh 😂 can't lie though, it's a good learning experience for you to be able to take your car apart like that. I've done all the work myself on my car so far, but watching this in fast motion made me realize the nostrum injector upgrade might be the first job I take to a mechanic
@@EnthusiastPOV just wondering lol
ye hell na wtf im takin my q to the shop to get sum bigger injectors this not it
Why would u have to pay the labor if u bought it to dealer
Maintenance isn’t free unfortunately. Dealership isn’t responsible for something like this.
@@EnthusiastPOV car under warranty with stock injectors thought that would be covered
The Injector failed using E85 I wouldn’t waste my time attempting to get something under warranty that I know would void it lol
Yea so you gotta get some Texans and Astros gear dude lol
Hard pass lol
@@EnthusiastPOV LMBO.....
I fucking hate direct injection
