Ok guys... so I didnt hear the noise yesterday when i got home... althought I had to maek a stop on my way home, so it wasnt a continuous drive... so I'm still not a 100% sure... but it wasnt making the noise when I got home... car is at home today... next time I drive to work I'll update...

Noise Gone!! ... so the ECM reprogram, in combination with Ester oil worked !!

i gotta bring my car in to the dealer this weekend cause my engine sounds like complete sh*t when its parked.. bunch of clicking noises.

bill90879

I think those clicking noises are normal... I hear them too, I think someone said something about the coils cooling down or something??

^^ i dont think do, cuz i have the same problem, however my friend has the same car as me n his doesnt make any noise, mine is soo freaking loud, it just clicks a way..argghh ..i went to the dealer in montclair and they said they couldnt hear any noises, so i figured out its after driving a good 10-15 mins does it start to make noise..

Seems like Nissan is pushing this "ester oil" garbage these days... of course, that makes a simple oil change insanely overpriced. Meh!

I'm getting a feeling this is some sort of stop-gap measure... they may know what the problems are, but instead of dealing with them (cost), they push the ester oil onto customers, which I don't think in any way is a permanent fix. I mean, who in their right mind would pay that much $ for an oil change?

Don't take it to Montclair. Nothing but a bunch of d-bags work there. Take it to Riverside and ask for Ben Soster. He's a good dude.

So please keep us updated cuz I also had the ECM reprogram/Ester oil TSB done on my '08 G37. Noise completely gone afterwards, however, I have about 1500 miles on it since and the noise has returned. Much more lower in volume/loudness, but there nonetheless. I haven't taken it back to dealer yet, but will be taking in soon.

Anyone had the VVEL TSB completed and had the noise return? Any comments appreciated!

Me Im thinking about should I go for regular oil or ester on my next change.

Glad you've eliminated your problems. I too am using
the Nissan Ester, but plan to switch to Redline due to
$12.50/quart vs $8.50/quart for a much higher percentage
of ester base group.

There is plenty of convincing documentation as to why "ester" is
recommended in the VVEL. The VVEL has some incredibly tight
tolerences and generates heat very quickly. The nano-technology
in the Nissan Ester oil really does a great job of reducing friction
and the resulting heat in the VVEL system, but I have doubts
about the ester content and base oils used in it due to it's
proprietory formula being unknown except for what is available
in Nissan's "white papers". Ester bases are far superior to other
base groups...it's polarity causes it to flow towards heat instead
of away from it like other base groups. It's polority give it a
lingering and sticking property that provides superior pressure
build-up as compared to other base groups. Ester will
naturally flow into much tighter spaces than other base
groups. Since ester molecules "seek" contact with the metal,
it provides superior protection from varnish and sludge formation
that over time, other base groups will just flow over.

The VVEL throttle is driven by a motor-actuator mechanism
that regulates the intake valves......as compared to the previous
variable valve systems that responds to a "butterfly" valve
first. The speed of oil pressure building in the drive spool
has direct effect on "throttle response" in the VVEL....it's
an entirely new mechanical concept. Simply put, ester builds
pressure faster, allowing faster valve reaction in the VVEL

Some say that Nissan's recommended use of their oil
is simply marketing hype, but a little research into
why they developed their oil after these issues
started showing up and all the examples of "ester"
oil being part of the solution certainly ought to make
the "naysayers" do a little research and rethink
what kind of oil they've using. The VVEL
likes and responds to Ester oil in it and their
are very real mechanical reasons for it.

Me also!

The VVEL noise stopped after running the ester oil for 3750 miles but then I switched to Mobil 1 hoping for 7500 mile oil change intervals. Been running Mobil 1 for about 2700 miles now and the VVEL noise comes back every time I drive it hard--very noticeable increase in engine idle noise.

I will be switching back to nissan ester oil at 18750 miles (my next OCI) and staying with that going forward.

I just heard my car doing this (2nd time in a week). I used to put only nissan ester oil until about 11,000 and no noise or weird vibration. At 11,000 I switched to synthetic (done at the Infiniti dealer). The car was running fine for a good 2,500 miles but started to notice this loud engine noise when the car in idling.
Going to make an appointment for the car... but I'm not too happy that my oil changes will cost me $130 (that is with discount). What a ripoff!

Keep up updated on those who had these problems - and if any of them came back.

Thanks

I have this same problem but I have a Fujita Short Ram Intake. Would that effect it at all?

Nope. have your dealer perform the TSB. It's more than likely the VVEL actuator.

Took my 09 sedan in today and they tried to tell me it was y radar detector was rattling against the rear view mirror.... Changed the oil myself to redline 5w30 and after about 20 miles I still have the noise..
