Jeez, hopefully that's the end of your worries.

 

So that high pitched sound is not normal under full throttle near redline?

 

I know nothing definitive other than the fact that it has apparently gone away. Given the condition of my timing chain and guides, i have to wonder if it was the result of the secondary tensioner not recieving full oil pressure causing the chain to hit the guides at high RPM.

OTOH, it could just be a coinidence.

 

Would you mind posting your invoice (list of parts) for when they replaced the rear timing case?

 

My 2012 just threw the Dreaded P0021 and P0524 codes....
Initially I notice it wouldn't downshift into the higher rpms, it would literally cut power at around 4K. It first threw a P0021 and P0300 and started running really rough. Replaced my cam position sensor, and reset codes. Sensor helped the car run smoother and then shortly after driving 15 miles it threw the P0021 and P0524. Cars going to the dealership Tuesday next week. Yay!

Mileage 51k, bought with 31k on it a year ago lease return.

 

Yeah, your gasket is blown. Make sure they give you a nice loaner. I got a Q50 with the new 3.0T

 

Ya, if it is the gasket, which it seems to be. I'm wondering if keeping the car past 70k is worth the risk of having this happen again, out of warranty, yikes! Has anybody had the gasket replaced and it failed again?

 

Not that anyone on this forum has posted. After having mine repaired (out of pocket out of warranty) I sold it shortly thereafter before I could find out.

 

Have the dealership show you what those gaskets look like so we can see if 2012+ really has metal or paper gaskets.

 

What made you sell it after you paid for fixing it?

I just had mine fixed, and will keep it for a while.
The repair isn't that expensive if you don't get it done at a dealer.
I had mine fixed at a Nissan performance shop, and it cost me $2100CAD, which is $1550USD, that includes new crank sprocket and timing chain.

 

My wife was done with Nissan/Infiniti after the poor experience. No cinfidence that problems wouldn't recur. I didn't disagree with her.

 

For many it takes one bad experience to sour the whole brand. That's how I feel about kia/hyundai after my 2 month experience with an optima sx back in 2011. The car refused to drive straight, requiring constant adjustments yet would never find a sweet spot.

 

I wish lawyer who is a G37 owner would have this issue and decided one day to sue Nissan and at that time subpoena records to see exactly how many engine Nissan has already fixed.

I am at 66,000 miles right now and still running strong but would love to know exactly what the chances are. I still have my original G35 with 256,000 miles and technically zero major issues. For some reason I don't think my 2012 G37 will last that long.
And that was my intent when I bought it.

 

The G35 has the same gasket issues. It's hit or miss, but no reason the engine can't make it a quarter mil.

 

which year of the G35? I have the original first run of 2003.

I don't remember ever hearing from anyone that this happened on any 2003 or 2004 models.
