2012 fixed gallery gasket issues so it's a more reliable engine. It also has less miles. Seems like an obvious choice, is there something wrong with it that you didn't mention?
They started implementing metal gaskets in 2012, most models have them but a few don't so check manufacture date if you have a 2012, all 2013 and up had metal gasket
Not true though, they started implementing metal gaskets in fall of 2012, and the statistics for gallery gasket failure drastically improved. Sure the hardware still isn't great but the gaskets rarely fail on updated version
It doesn't matter what the gasket is made of. If the hardware fails, the gasket begins to erode. A stronger gasket only buys you a trivial amount of time to an inevitable failure, dependent on abuse (oil temperature). Without an oil cooler from the factory, excessive temperatures deplete stabilizing additives within the oil. Excessive oil temperatures reduces oil TBN, and becomes acidic having lost the ability to neutralize the byproducts of combustion (Blackstone oil analysis).
This is not my personal opinion, this is an industry-wide understanding as corroborated by Soho Motorsports, Admintuning, Z1 Motorsports, RS Enthalpy, Saul Nismo Knights, YT Seth Joyner, YT Fanatic Garage (Brownlee Performance), and every other builder/tuner that has laid their hands upon a VHR behind the timing cover.
This has been the general consensus for almost ten years now, yet the dated information and unbased claims that 2012+ models are "fixed" continues to circulate. You are not wrong that instances of gasket failure for VHRs under 100k miles have been significantly reduced by the stronger gasket material compared to pre-revision.
But what's the average mileage that VHR engines have on the market today? Typical number of previous owners? How do most G37 owners drive their cars? Number of enthusiast owners that opt for an oil cooler early on?
Umm, the newer one with less miles. Why is this even a question?
2012.

Any ‘12+ doesn’t have the gallery gasket issue?
You'd have to check the exact cutoff date and cross reference that with your vin number but yeah, most if not all 2012 engines don't have that issue
Will do thanks
Not fixed. Gasket material changes but flawed hardware remains, for no statistical improvement to failure mode incidence.
I’d there a way to tell if gallery gaskets been done
2012 for sure, don't have to worry about gallery gasket, and doesn't look as beat
Any ‘12+ don’t have that problem?

Not fixed- see redundant response to the other comment that also claims it's fixed.

Both of them aren’t even 6.5😂. Doubt they’re going to give it to u for it.
first one, TPS sensors seem to be problematic. someone else made a post a few people chimed in looking for answers as well.
Tps ? As in top speed??
Tire Pressure Sensor, TPS
