Looks like 2013's arent immune from rear timing gasket failure

man but he has a 2013 G. if they had pre assembled motors just waiting to get put into a car, i would think they would run through their stock in the 2012 run.

It seems like there's plenty of screws holding that plate down, but from the pics I've seen that gasket appears to be tearing and coming out at the same place IIRC, so maybe there is an issue there too???*****Another scenario here, possible that since Nissan/Infiniti replaces the whole assembled cover when doing this R&R they have all these covers assembled (w/ the crap gaskets) and ready to install on new VQs. Rather than getting all the covers retrofitted w/ the new gaskets they just installed whatever inventory they had???

From what I can find, there were three different revisions made of the timing cover assembly. Does anyone know if there is any way to determine which revision you are looking at? Is there something stamped on the piece itself?

I have been told directly form one owner that a service department did just replace the gasket only at his request rather than the entire rear cover. Saves a number of hours of labor. However I'm certain that the repair came with no warranty on workmanship because of the issue you cited about not having torque specs for the bolts.

From what I've been reading from various sources the two different metals (the aluminum timing cover and the steel oil gallery covers) are the main culprit since they are expanding different from each other. This causes the crappy paper gasket to get exposed on the edges when the gasket cover & timing case have the most gap, oil starts to soak into the gasket from the inside out weakening the gasket and the high oil pressure eventually pushes the gasket to the point where it tears and comes out from under the cover. Wonder if it's possible that even the metal gasket gets to a point where there is a gap between both metals and that gasket just starts leaking (rather than blowing out). Victory, hopefully they can let you inspect that cover they removed and see what that gasket is made of, they at least owe you that.

Mileage is all over the place and the percentage seems low.
In my opinion the overall design of the rear timing cover is flawed. It has been revised a total of 3 times, with a total of 4 different versions.
13500-EY00B: 08/2007-11/2009 (2008-2009 Models - some early 2010 models)
13500-EY01B: 11/2009-06/2011 (2010-2011 Models)
13500-EY02B: 06/2011-06/2014 (2012-2013 Models)
13500-EY03B: 06/2014- (2014-present)
The 3.5 HR has 1 revision and a total of 2 designs.
So looks like the real safe model is the Q40 version of the G37.
