^ When oil gets in the combustion chamber, it kills oct rating = pinging.

Flip side: after ~2500mi on my replacement, I started pinging again with much less OC than original revup VQ. New issue I'm working on as to why...

Congrats on your replacement approval

 

should I take my mrev2 and spacer off... kinda a pain if it wont effect anything.. in my oppinion it shouldnt but then i guess its better to be safe

 

For everyone that did get their engines replaced, did the problem go away?

Did anyone have the problem even after the engine replacement?

Thanks!

 

^ See last line of my SIG...

 

Damn that sucks, are you the only one or the very few, or is it common to have the problem again after replacing the engine?

This is really making me steer away from the 05, but I also really want the 05 over the 04....

 

^ I'm not the only one. It's ~50/50 I guess. Some no more OC, some with mild (me), some enough to be considered a 'fail' and qualify for another replacement. It's about the same with the 350Z's too on their OC thread.

Keep in mine, it's the 6mt's that are plagued the most with this, not 5at's.

Despite my OC, I still love my 06 coupe (with lots of warranty left too lol).

G/L with your decision.

 

Hi... When last we traded info a few months back you said that on your next oil change on your new engine you were gonna check to see if your dipstick L-H represented one or two quarts of oil... Did you go ahead and do that and if so, what did you learn??? Just curious... thanks... bob..

 

After my replacement I started to chart my readings at least once a week to compare miles and OC each oil change interval. See below for the comparisons:

9/02/08 --- ~12mm *old 0-16,262 miles (Engine Replaced V2)
10/05/08 813mi ~5-6mm 17,075
10/11/08 970mi ~8mm 17,233
10/18/08 1100 ~9-10mm 17,360
10/26/08 1253 ~10-12mm 17,516*no oc*
11/02/08 1382 ~10-12mm 17,645*no oc*
11/08/08 1511 ~10-12mm 17,774*no oc*
11/08/08 ----- ----- 17,785 *first oil change*
11/09/08 10mi FULL 0mm 17,795
11/16/08 125mi FULL 0mm 17,920
11/23/08 251mi FULL 0mm 18,046
11/30/08 409mi FULL 0mm 18,194
12/07/08 631mi FULL 0mm 18,416
12/13/08 766mi FULL 0mm 18,551 *no O.C.*

It is definitely an improvement but I don't know if cooler weather is the culprit for *no O.C.*. I'll keep checking till summer and will post when she starts drinking again, but I'm hoping that there's no more issues concerning Oil Consumption.

Goodluck on your decisions, but hopefully this helps.

 

Thanks alot man for the reply. I'm still in the hunt for both the 04 and 05. I'm starting to lean more for the 05, but am still browsing both incase I find a hell of a deal on a 04.

Anyone else have or haven't had OC problems after the engine replacement?

Thanks.

P.S. Has anyone ever made a thread to see how many people on the forums that DIDN'T have any OC problems? If not, I think it's time we find out. Majority of what I keep hearing is from the people that have it...

 

Oh SNAP!! I completely forgot and just changed oil too. Sry about that

Maybe during this interval I'll know, but only if I have to add any make-up oil on this V2 replacement (for my sake hopefully not)
If no make-up oil added, I'll try to remember next service and see if first 4qts = L on my stick or half way L/H.

 

Funny how these questions come up again after they were discussed and put to rest over a year ago. Maybe not discussed on this thread, so here goes...

4 quarts = L on the hash mark of dipstick. Had this proved over a year a go when we were still trying to get a TSB issued. Myself present and the dealer technician, drained the oil, filled up 4 qrts, let it sit for 20 min, took a reading and BAM, it measure on the “L” hash mark, hence the amount of oil between the L & H hash marks is 1quart. It’s also an industry standard on other makes, that the “low mark” on a dipstick is 1 qrt LOW. Makes sense to keep the industry on the same page.

See post on this from 12/01/2007

^ Thanks for that confirmation. I completely forgot you did that 4qt test at the dealer waay back then.
So much info in all these long G35/350Z OC threads. Hopefully that will help/confirm with 'diitto'.

When I would be a quart low 'L' mark on my old VQ burner, it would always go back to 'H' when I added a quart.
Essentually the same test with same results/confirmation as yours.

 

On another note...
If anyone here is interested in how these TSB warranty replacements are doing internally with it's build and break-in, check out my most recent used oil analysis (UOA). I'm 06CPV35 over there.

Hi Guys,

I've been doing alot of reading on this website about the oil consumption for quite some time now as I've been monitoring my own oil usage.

Last time I did my oil change, I had lost 3 Qts in 5000km! (yes i'm from canada).

Now i've been monitoring it and I lost 1.3L in 700km so i'm obviously burning alot of oil. I took it to a dealership here and they topped it up and said come back in 1000km. The only problem is my 2004 G35 is at 103300km and my warranty is up on Jan 3rd . 2009!!!!!

now you know my scenario, my question to you is:

IF I put on 1000km asap and take it in, will they top it up again and ask me to come back in 1000 and then determine if it's manufacture's defect, or will the begin the testing immediately? And how long does it take to determine if it's a Manufacture's defect so it is covered by warranty? Finally, What are the other possibilities of an overheating engine, that would not be covered by warranty???

Thanks for the info

 

^ Don't know what 103,300km is in miles off the top of my head, but US powertrain warranty here is 5yrs/70,000mi which ever comes first. Sounds to me like they already started testing with you. Check your paperwork to make sure they did. Yea they most likely will do a couple more of those OC tests on you. Year 2004 doesn't follow 05-07 TSB OC test guidelines.

Bottom line: Here in US, if you started official testing for a powertrain warranty issue before warranty expiration, believe they must honor warranty when they finally determine replacement is needed. Key thing is official testing/documentation of issue started before warranty was up.

Don't know about Canada, but hope that helped. Might want to confirm with Infiniti Customer Care up there if it's the same as what I mentioned here in US.

-edit- Overheating could be a sticking thermostat. Not sure if that's warranty item or not.
