Oic...thanks for the info.

 

Because the new VQ received a new piston and new rings to handle the "higher revs" the new REV-UP engines were made to do.

Previously, those dumb **** at Nissan decided to up the REV w/o upgrading the INTERNALS to handle it... What kinda dumb DeVRY Graduates are they hiring over there at Nissan?

Even fuking Honda knew that increasing the REV-LIMITS would do damage to the internals if they didn't upgrade it.. Which why is the internals of an LS is different then a GS-R..

 

Got a replacement engine this year.
If anyone is interested.. here is my post story:
first 1000-1500k oil test according to TSB -- verdict "LOW"
.. filled up oil ..
Now I am at 2200k (1000-1500k testing #2) -- I checked oil levels and nothing has changed.. still way too LOW

Anyone here got a lemon claim filed? Any results?

 

What year's ur ride?

Just an update... took mine back to inquire about my original OC issue.

So the service guy says I need to redo the test... blah, blah, blah. Though I wasn't happy, I agreed. Well, he calls me 4 hrs later saying that they'll go ahead and replace the engine. Apparently, they had an engine available to do the swap.

Things to note after I received the car back:

Since this is a new engine, it will require another break-in period. 1200 miles w/o going over 4000 RPM.

They don't reset the mileage. It stay on whatever it had when the repair was done.

The standard warranty doesn't restart. It just continues like before.

Now, regarding the 5th gear grinding.... Their "analysis" is that I needed a new clutch. They said that's causing the issue. Since I didn't really research this as much, I agreed to have them replace the clutch for $400. Now, if this was truly a clutch issue, won't it NOT shift on any gear? Bastards!

Anyway, with my $400 spent, I still have grinding issue shifting into 5th gear. Headed back there next week and give them a piece of my mind.

 

Can someone please tell me if this oil problem exists on the 08 G35XS?

thanks

Horrible... Just horrible. I don't drive the G as much and theres no way I can come up with 1-2 for the test.. I'll just let my bro drive it.

 

when i had grinding in 5th gear i took it to infiniti of montclair, they new exactly what it was and replaced my tranny.

 

You have the next generation VQ block that appartly doesn't have this plague.
^The most recent TSB this thread pertains to and what years/models are affected.

 

thanks...

I had my engine replaced around 30k im at 45k now..

the car did feel sluggish inthe beginning but after almost 10k.. it became what it used to be.

however my unlike u, my OC issue seems to be resolved.. sorry to hear bro.

 

Infiniti called me the other day, new engine is on order. I hope this resolves my issues. I wonder if they would let me buy back the old engine, or even just block. I would like to build it for FI. I'm really liking the Power Lab ST kit.

 

Wouldn't hurt to ask about buying old one, but have read from other members and Z members too, that they send it back for the engineers to assess why it failed.

G/L and hope your replacement is a winner.

 

hey all. first post.

i'm really happy this forum exists. i wouldnt have know about this issue w/o it. so thank you.

i just bought a '05 g35 couple w/ manual transmission. so my car may have an OC issue. i've started my own OC test to see whats what.

i have a few questions for you guys from things i've read in this thread...
1. what does VQ mean?
2. what does rev-up mean?
3. i've had cars that consumed oil before. granted the engine should not do that, it was otherwise mechanically sound. i just had to monitor it. is that the case for these motors? if my motor does have an OC issue, but it doesnt fall in the 'No Good' range... is it that big of deal?

thanks for any info.
