Not because of exhaust btw. It's because of an 'oil consumption problem'. My Z is a fattiboombah.

I had the same issue with my 2006 G35 6MT, I purchased the extended warranty which covered all the non-sense related to the oil consumption problem.

I appreciate your input but let's get this back on track. I've attached a picture of piston damage done by a lean engine. This is the engine failure I'm referring to, not blowing an engine.

I would drop the $$$$ on the Xtended warranty if u don't work on the Z urself.
For the following reasons:
1) oil consumption
2) oil overheating
3) plastik CSC failing
4) rear diff silicone bushing tearing
5) I could go on, but I refrain....
The Z is a cost-cutted POS, but w/the right mods and time dropped into it...it can become a fun reliable daily. :D

I guess I shouldn't speak in generalities. Not all of them were blown engines. there were other types of engine failure from ringlands to piston failure. Pretty much everyone of these experience i've seen where the person had a tune the warranty claim was denied.

can someone explain what osiris does? it's not a tune?

I'll make an uneducated attempt at it.

Edit:
I just did a little research and it appears that it is specifically for Nissans & Infinitys and consists of an interface cable and software. As I understand it, you can make adjustments to your factory ECU on the fly. Perhaps someone with more knowledge will come along and confirm this.

hopefully it will be worth the $300 then

Ive had the steering lock replaced on my 09. My Navi headunit controls for AC and Radio wont work when you turn the nobs, my clutch switch has gone bad so now I push in the clutch and the car wont start.

BUY THE EXTENDED WARRANTY! Sadly, I bought mine used so no chance on getting it extended. Costs me out of pocket for the last 2 issues.

Are we talking an extended "Nissan Factory Warranty" or are we talking one of those after-market warranties a Nissan dealer might try and sell you?

I'm glad I asked. And it looks like just a powertrain warranty probably isn't enough.
Originally I was thinking a route 66 warranty, but I see a 2012 Z for sale, so I would assume since it's still under all factory warranty for another 6 months that I could extend it through Nissan....
