Engine noise issue with my 2008 G37S

[Jacko3]

I will never be in the market for a VQ35HR engine---just kidding . Seriously, what could be better than the VQ35DE? The way I feel so strongly about the VQ35DE engine, I may be putting another engine in my ride once it ages, rather than buying a new G in the future. Nissan had no idea they had built a nearly indestructible and bullet proof engine. I still don't understand why Nissan quit with the development of the VQ35DE and rather went for the VQ35HR. After all, the GTR has some of the parts and spirit of the VQ35DE and RB26DETT. Man, just sitting here thinking about the VQ35DE engine sends really ecstatic shivers through my spines. This is the only engine I know that can wear me out and bring me to my senses everyday, and with a big grin on my face from ear to ear . A day in the G is a day of therapy for me. Thats right!

I Its just very annoying to hear this day in day out at work and people expecting a new state of the art motor that is a v6 and puts down amazing power n/a and is effiecent as hell. you HAVE to pay to play. Who here remebers the old saying...fast, cheap, reliable...CHOOSE 2 thats all you get.

Seriously it is not a problem it's just new technology. It's the way it is going to be from here on. With the new fuel economy requirements all engines will need to be more efficient and will most likely require new better oil. Now the factory stuff is no RP or M1 but it works and well at that. If you want maximum performance out of your 37 use the right stuff.

One thing i do find funny is how everyone speaks about this like thier an expert one person i saw imperticular would have to be everyones good friend sentiantbydesign or however you spell it. You claim someone is not qualified to say something about the matter of this, yet you yourself are king of it? thats how i read it at least. Heres one question i have for you what makes you an electrical engineer? do you know what your grounding kit does? really it makes the engine bay more crowded gaudy and skews signals on 5 volt systems of the car. Don't believe me take out a fluke 87 or equivelant and do a voltage drop test from the negative battery cable to the dash tube on a stock car and then test one of your grounding kits. I can already tell you your going to have a skewed number....why you ask? too much resistance through the line. your just adding wieght and unneccsary wireing tto the car that has zero benifet at all. I'm not claiming to be a electrical engineer but i do know what i'm talking about.

You're calling SBD out for not being a super expert, and then you expect people to believe you even though you're not an expert? Wow dude....just wow. You get the

ANYONE that knows anything about car electronics knows that improving the quality of the grounding lines makes huge improvements in the way the electrical systems work. Why do all of the A/V guys use grounding upgrades? Because it helps the system out....You just opened a whole new can of worms buddy...

Also note that your entire "rant" goes against the entire idea of an enthusiast forum. You bash people for wanting to modify their car and use other products other than the "factory" ones. If I did this, my car would slide all over the map because of crappy OEM tires. Real enthusiasts find what works best for their vehicles, not what someone else tells them to use. If Infiniti told you that driving your car off a bridge would help with it's gas mileage, would you do it because the manual said so? People aren't cutting corners by using something other than the OEM part, they're simply looking for the best option for their car...

Seems like thread is about to blow up I am a mice among giants Great ones, I am unworthy.

[Tampa G35 Sedan 6MT]

Well here goes a huge rant.....

For the Nissan GTR it is a 0W-40 mobil 1 only, if any other oil is used in that car BYE BYE warranty. So the oil in the 3.7l is definitely different than the oil in the GTR. This is not a case of whats good for the goose is good for the gander.

The GTR was designed with that oil in mind kind of like the 3.7hr was designed with ester oil in mind.

So if this ester oil is so great... Why don't we put it in the GTR...

I don't really know much about this but I'm think on a science perspective.

That would be like buying the big Benz and taking it to walmart to change the oil.

You don't do that... Same as you don't buy a KIA and take it to BMW to get the oil changed.

Why would you put an oil in a G37 that cost 16 bux a qt, when the oil that is used in the GTR (Better more expensive and technology advanced car) Uses oil that is 6 bux a qt..

Something IS WRONG! AND THIS IS A "ISSUE" THAT NEEDS FIXED. that is a major design flaw on Nissan's Part.

Oh and don't piss us off and then apologize for it! It doesn't work that way around here! So you need to state everything in a polite manner! Not that someone with 8 post really serves as a creditable source.

And if you disagree with something that a Member like SBD is doing... state something and back it up... Make sure you put in their that it is your opinion and remember the rules posted above!

All I got to say is if this is a problem to you... You need to get a new job, and stay off the net! It is an easy fix IMHO!

+1 on that.

Post count doesn't have anything to do with knowledge, you guys should know better than that. Although brash he has a point on this topic. While the SBD sh*t is another thread and discussion, the main topic here is ester. It is not a design flaw or a problem, the price at this point is high but supply and demand would dicatate that it should drop once there are more cars with it and more oil to be used.

Resume topic and lets try to stick to one argument at a time

[Tampa G35 Sedan 6MT]

Sorry steve that you had to know this fbpem1

he might know what he is talking about... but when you are here you need to be polite!

No need to talk like you are sitting on a pedestal looking down on us who only are asking for information!

Don't talk down to us because you understand or know something that most of the public doesn't know.

be informative and bring good information or opinions... I don't care what it is you are telling us but be nice about it.

It really gets me that everyone can't discuss without some pompous a$$ who thinks he knows it all and being a jerk comes in and ruins a really good discussion!

What really sucks is this is my 2000th post! not how I wanted to cross that line

I will give you that, like I said the way it was done was brash and not called for. The reason I like Nico G forum is because for the most part we all have adult conversation without petty name calling and poo flinging. Well for the most part.

Congrats Tampa

This place is turning into driver...... lol

that hurts my feelings hahaha, i sure as hell know more about electrical system than someone making a ground kit to fund modifications for a car they can't afford, which is what the whole ester oil issue boils down too...cost. I have a log sheet and so does nissan/infiniti of why ester is declined or approved on every oil change that goes out the door.

All I got to say is if this is a problem to you... You need to get a new job, and stay off the net! It is an easy fix IMHO!

I never stated it is a problem for me what so ever i like ester oil if i was to own a G37 it would have ester oil in it although i don't i just work on them. The easier fix for the "problem" is to run ester oil and have your car putt on down the highway like it was designed.

ANYONE that knows anything about car electronics knows that improving the quality of the grounding lines makes huge improvements in the way the electrical systems work. Why do all of the A/V guys use grounding upgrades? Because it helps the system out....You just opened a whole new can of worms buddy...

People aren't cutting corners by using something other than the OEM part, they're simply looking for the best option for their car...

I stated nothing about being against preformance i have a modified car always have and always will, thing being i use whats best for the car.

Now heres something you fail to mention how many cars that can actually put a number down at the track are using ground kits or the likes of? i can't really think of any keep that in mind.

So if this ester oil is so great... Why don't we put it in the GTR...

Something IS WRONG! AND THIS IS A "ISSUE" THAT NEEDS FIXED. that is a major design flaw on Nissan's Part.

Ester oil is great for the 3.7hr, not for the 3.8 in the GTR as i stated two differant engines requiring differant fluid properties simple as that.

I kindly take back the "sorry" i posted in there, i am a very brash person and when i feel strongly about a subject it tends to show more times than not. Although anyone that really knows me does know i have the knowledge and experience to back up what i say, and i do volunteer anyone to go out and do the voltage drop test on a min/max record setting on a fluke 87 or equililant, and they can see for themselves. I have personally see too much resistance in the body skew 5 volt signals don't believe me i'll send you a bad negative battery cable to back it up lol.

Wow I left for 2 hours and there it goes the thread is upside down.

Anyways I think I missing a part. There is something wrong it is not how it designed. If that's how it was designed then why the owners manual doesn't state to use only that type of oil. Also why needed a reflash for the ECU? Am I missing something?

Can somebody tell me what is in the reflash? What data changes?

Ok here a quick reply so I can get some work done today. LOL The reflash allows the VVEL to change its base (idle) parameters. It has to do with the noise related complaints. The oil was not mentioned in the manual b/c there was something lost in translation, IDK not something I did that's just what I was told from higher ups.

zozo~ I really like that saying

[Tampa G35 Sedan 6MT]

Thanks Guys... I feel like I have been here for ever...

fbpem1:

You are going to have to control your Brash here!

Ok and we all own G35/37... What kind of car to you drive and race/tune... or what ever you claim you do to the cars?

If you say honda you are going to be for the comment of who can't afford what!

and we don't know you and you have gotten off on the wrong foot with me as well as many others here. Build your creditability and then you can be a pompous a$$ on occasion!

Thats the best I can offer you!

I mean we can start to talk about law and I am sure I could blow you away on anything you might think... I could also get on my pedestal and make you look like a moron... but that wouldn't be very nice

Grounding kits are not a performance mod. I'm glad your self-proclaimed electrical genius exists. You still have no credibility on your arguement about the grounding kits. Good for you - you have a log sheet. I'm glad you cleared that one up....

I never "failed" to mention anything about cars at the track running with grounding wires. It was never an issue. And now that we're here, any real car running at the track doesn't need grounding wires, as the car is usually built with better elecrical systems, and doesn't have all the crazy stereo's, climate controls, etc, as a normal car does.

And you have a modded car, do you? That's certianlly not recommended by the mfg. You've succesfully voided your warranty and didn't take into consideration what the mfg wants you to do. Bad boy. Take your own advice.

[Tampa G35 Sedan 6MT]

Welcome back zozo..

And I think you are right... we are still missing something!

Steve what are the actual parts that are being lubricated better by this ester Oil? Where is the noise coming from/being made by?

Changes the base specs for the B2 VVEL (variable valve event lift) actuator, which boils down to being a a window motor a (direct current motor) put current 1 way it moves one way then put current the other way and it moves the other way. hope that sheds some light on that.

Also i never said i was angry i'm not a very angry person persay but as i said i come off like a d!ck on the internet always have always will. Oh well

No its ok... he drives/races/builds honda's!

they don't need Grounding kits because they produce so little power or electrical current that you could jump start one with an Ipod

I am sure we will hear more later on and it will clear the sky. It is just weird see Infiniti doing this. It is usually Europian brand who gets this kind of threatments. You know the car starts woth the B and finishes with W and they throw an M in between.

That's why many of those guys are so happy just like the oilcooler issue and ran flat tires,etc

Glad we dont have issues like this regularly.

Thanks again Steve as usuall.

so your the one who's allowed to talk like an *** here? i guess the 2000+ mark comes with perks

I have nothing to prove in everyone's eyes here, i don't have to work with you and you don't have to listen to me although you should listen to facts, and i actually didn't start this whole thing i may have blown it up but your all powerful ground kit mod guy did that when he said someone was unquialified to speak on a matter, so i basically said he was unqualified to sell something that "works" lol

Take what i say for what you take it for do a little research and i can assure you, you will come up with the same answer. That being said ban me if you wish talk sh*t more it dosn't bother me what people say about me on the internet.

To answer your question yes i have built and tuned honda's for years always have and always will, i'm working now on mazda's DI motor in the speed since i think its a good platform. Heres the thing about your no power comment, there is an 8 second honda and more to come next season. power is power is power fast is fast is fast, you should understand that, but wait...no...not in a 10,000 pound G

i love drama slow day today at work

[zozoka1212]

We are here to have a good time change some information in an inteligent way if you don't like it please move on and thanks. It seems to be you don't care much but we do. To realize your anger is the first step. You have anger and you try to release it over the net for some reason you can not do it person. I still stand for the saying.

Holding on to anger is like graspng a hot coal with the intent of throwing it at somebody else, you are the one who gets burned.

I am only returning the favor!

Now see how pissy you get when I start to talk about "your" honda's

And yea what you said about power is true but your are still driving a ricer honda that sounds sh*t and looks like crap.

Honda's are like tampons...every pu$$y has one! But only you can tell us if the shoe fits!

most of the time the anger on the internet is due to other shortcomings in life/women/bed

But that is always just on assumption

DJ

[fbpem1]

you should really stop reading emotion into my posts since there is none there its like you want me to be angry or something lol. If i was angry there would be a totally differant. Also i totally own up to my shortcomings in life, bad in bed, small pen15 lol. I personally could care less what you say about honda's everyone has thier own opinions mine i like 4 cylinder turbo cars, sue me, you like large underpowered v6 cars i don't fault you for that what so ever.

As i said i'm not pissy/angry or whatever you you can talk about whatever you like about honda's. As i don't own one at the moment but i will agian in the future i know that.

I would however like to make it known i don't dislike infiniti i think they make a high line entry level luxury car.

[Tampa G35 Sedan 6MT]

Now you are learning... that last one wasn't so bad!

GO WOOOOSSSAAAAAAHHH!

I think what you might be missing is that VVEL is not a purely mechanical function. There are references posted in various forums to a "white paper" published by Nissan describing the VVEL operations.

The software update, if correctly applied, pretty much seems to cure the problem. The people who said it didn't work had it done again, and it worked the second time around.
