^^ so there it is for the G any word on this for the Z?

LMAO perfect way to ensure repeat repairs Nissan, GG.

Oh lordy...not again....06 Z33 RevUp MT replaced...I am having too much fun with this car (Z34) for another OC issue.

Interesting. The chart shows that if you burn >2mm of oil per ~500 miles (beyond 9mm) then there is an issue. Is the dipstick the same on the 370Z and the G37? Probably so.

Subscribed. I can only imagine the problems I'll endure if any Nissan dealer in my area tries to replace the engine. Even if I had consumption issues, I might rather refill the oil frequently rather than run the gauntlet of engine replacement by numbnuts.

There are a lot of dealer horror stories on the Z33 Revup engine replacement on my350Z oil consumption thread. Ya just don't know who is out there turning the wrench. The Bros 06 Z33 engine swap was perfect with our local dealrship in Roseville / Sacramento area. It was their third engine swap and it was flawless.

I have been tracking both Z34's oil readings every week and the bros is in the safe zone by a long shot. Mine was close to No Good at 1925 miles at 10mm oil consumption. Thereafter it stayed in the safe zone through out the 5k oil change interval. By the time it hit 5k miles there was 16mm of oil consumption which equates to about 3/4 of a quart. No cigar this time around. Then again the 06 Z33 did not really start consuming allot of oil until the odo hit between 22k miles and higher. I am currently at 21k miles on the odo. So if it holds true to 06 Z33 engines, this engine could start consuming more on the next oil change interval. Fingers crossed it does not.

And I traded my 2006 MT for a 370Z...

Its funny i read this today.. about 2 weeks ago i changed my oil at 5K interval, car now has 20K. To my surprised i only drained about 3 quarts and 1/2 which means the car comsumed the rest which is a lot. I need to take it to the dealer.

Hopefully you received a fair trade in value for 06. Sold the bros 06 for $15k with 15k on the new engine, total of 42k on the odo.

Ouch...yes indeed that is a lot of oil consumption. I would def get it into the dealer and at least have it reported on a service order that "customer states engine is consuming excessive amount of oil between oil changes". It's important to get documented on your file even if they do not have a TSB yet for the 370Z. It MAY help if you ever have to Lemon Law the car, although I believe Cali Law is 18k miles to have the issue reported to manufacture. Either way they would pro rate the mileage on the car if it ever comes down to a buy back.

I would also ask the dealer to start an oil consumption test on the car and if they look at you funny....then run fast to another dealer. You should be checking your oil weekly and when it’s cold (sat over night). The dipstick High / Low hash marks are 24mm between the high mark (hole) and the low mark (hole). And the mm between the high and low marks is 24mm which equals to 1 quart.

If this issue starts to raise its ugly head on the 370Z then a new thread should be opened, because it will get long. Just look at my350z thread, it's at 219 pages. RevUp Oil Consumption TSB and discussion - MY350Z.COM Forums

Wow... VHR has OC issue, too?

I guess only VQ engine that didn't have any OC issue was HR then.

Isn't the HR the RevUp?:shakes head:

subscribed

Nope. Revup is still DE.

You think they can try to void warranty because the car has bolt on mods?

They'd get taken to court unless the owner didn't want to fight over a $5k+ issue... There's no way they could prove minor bolt-ons were causing excessive oil consumption.

Especially if those boltons are intake/exhaust bolt-ons. I have been taking my car to the dealer for service, so hopefully that will help out if I have to make a claim.

Nope, RevUp was the 05 Anniv MT and 06 MT engines. HR came after the Revup on the 07 & 08 models.

They have to prove the mods caused OC. Like WarmAndSCSI said.

i have heard that the Stillen G3 Long tube intakes and running test pipes make your car run lean would that cause OC to your knowledge?

Subscribed

Yes, you and I spent way too much time in the OC thread at that other site a few years back :rolleyes:








:p

I saw an 05 VQDE in the dealer a few months back getting an engine swap due to OC, so they were not excluded from the ugly OC head. It was also under warranty for the engine swap.

I honestly do not know. I have Injen CAI and Nismo CBE and the dyno runs I have did not give A/F readings. Nismo CBE is far between test pipes. Interesting though, I am sure someone has dyno runs on theirs with A/F readings, it would be a matter of searching the forum

John, that seems like a lifetime ago. I am hoping to not have to go to that dark place again.

:iagree:

Yup... All year DE motors had OC issue. None so far has been reported for the HR motors (07-08 Z and G sedans).

And I haven't really heard any OC issue on the 08+ G37s either... maybe it's a 370Z isolated issue? Does anyone have the full TSB document including the solution? I'd like to see what's all involved in resolving this issue.

Thanks for clearing that up for me.

I guess I am going to have to start seriously eyeballing my oil levels. This is not looking like it will be any fun at all. Looks like I may have to hold on to my S13 after all. I was planning on selling it and going all in on the Z. Guess it is always good to have a backup plan.:ugh2:

dont worry about it too much dave.

just check your oil and u'll be good.

I check mine each week and its not movin.

the fill TSB is posted in post 1. plus it is only for the G's nothing out yet for thwe 370

^Yup, and the TSB is for 08+ G37's

I don't think you should have changed to synthetic that early...

Fuuu.... my bad Shumbs...

I just thought since it was from The370Z, it was for 370Z... This problem could also relate to the new M37 then? Man... no wonder Nissan wants to stop building the VQ and move on to Mercedez motors...

Half way down dipstick = 12 mm
200 miles = NO GOOD

Again this is for the G37 TSB, but it's still not good and I would...


Definitely get it into the dealer and have them record on your service record that "Customer states that engine is consuming excessive amounts of oil' and request the dealer to start an oil consumption test. It's important that you have them record this ASAP on your service record. Call it a cya (cover your arse) for any future decisions from NNA (Nissan North America) to replace your engine.

Subscribed. I haven't had my oil changed yet but right now mine's at about 13mm with 3300 miles on the clock. Of course, I have no idea whether my car was filled completely to "H" at the factory but worst-case (13mm) I'm still within the safe zone. I've also only checked the oil two other times and the level doesn't appear to have changed. I'll definitely keep an eye on it once I get my oil changed at 3750 miles.

Don't cars tend to burn more oil during the break-in period? In other words, wouldn't consumption be at its worst when the car is brand new?
