final update: Over 200 miles driven, codes haven’t returned and no more low-speed stalling. Still can’t believe I have fixed the issue. Definitely won’t be buying an Infiniti again lol. Thanks for your help and good luck to anyone taking on this repair. It can be done!

Now your ready to replace the galley gasket. Hooray! Seriously saved yourself some coin and you know your VQ that much better. Carry on!

Did you end up buying a new cover from the dealership? Or a used one?

Hi there, yeah I bought used ones off eBay. Both cost me about $450 in total.

haha yeah definitely not scared to do any fix now (but I would rather not have to do any fix lol.. I didn’t really enjoy fixing the car.

And “galley gasket”? That’s something I have to do as well lol because I’ve read about it somewhere.

Interesting you mention that, I think these cars are pretty easy to work on compared to most modern stuff. The only component that's actually difficult to remove is the stock headers. Everything else mechanically speaking is very straightforward, sure it might have quite a few components to remove but at least they're all accessible.

Plus there's a huge amount of resources available for FREE to help you out, things like these forums, and the ENTIRE factory service manual available online for FREE! You won't find that on most other cars, end up using a Haynes/Chilton manual and trying to just figure it out yourself.

As for the galley gasket, I wouldn't bother with it unless you are actually throwing the P0011 or P0021 codes, or if you have the timing chain off for any reason.

Thank you for clarifying my statement. I would in no way encourage anyone to change the gally gasket unless your throwing the codes mentioned. I bought an oil pressure gauge and have been checking the oil pressure every 6 months or so and so far so good.

Went with the harbor freight kit. Works great!

Im having issues sourcing this part. I have 2 mechanics and myself looking to find this part for an 05 infiniti G35 rev addition Manual.
But im told its on back order and has no price and no estimation of when it would be available.
Ive checked infinitiusa.com and z1motorsports.com as listed above but neither have that part for an 05 G35 or they have not responded
-- any help is appreciated

Hello guys

pleeeeeeease help me with my couple of questions

finally I found straight thread talking about my exact issue 🙏🙏🙏🙏

I having same problem that rpm sputtering and hesitating after warm up around 1k rpm

Now I have confirmed that I have this hesitating because my vtc after these following tests


Please note that my oil pressure is after fully warm up is around 8-10 psi / 2000k rpm around 40psi / cold start 80 psi , so i need to replace gallery gasket later too once I get low oil pressure codes or oil light on , I am living in dubai with almost some days 43 degrees weather I did manual relearn and OBVIOUSLY car is almost 90% better never like before

here the results after I unplugged my vtc and drive it

1 - disconnected both sides = issue gone completely

2 - disconnected right side = issue gone completely

3 - disconnected left side = issue gone completely

4 - plugged both sides = got the issue back


Pleeeeeease my questions

do I need to replace both whole cover or the magnets since I can’t find which one is Bad ?

do I need to replace them then do ecu update at the dealership or just replace and relearn ?

is it timing issue related with ecu or worn part ?

or just I need ecu update?

please waiting for any help I spent really a lot of money and now fix

Well, I would start by understanding which bank is causing your issue. You need to read the DTC. From there you can replace the VTC for the bank causing the issue. Replacing the VTC usually clears up this stuttering low rpm issue.

Just a quick update. Replaced both magnets with earlier posted pat number and issue hasn't returned over almost a year and about 10,000 miles. Stalling from a stop has also not returned.

That’s good news. I just replaced Bank2 and that dam magnet was a bear to get out. It took an hour or so of cussing but it finally dropped right out. Now I have an A/C climate control issue. I wonder how old I will be when I finally get ahead of all my repairs. Lol

with roughly the same issue i was told to spend $2600 on new VTC covers which i did. Turns out my original VTC covers had 0 issues. Id be willing to sell you the VTC cover i have for less then what i paid for them/.
As it turns out my timing chain snapped on which the mechanics who installed the VTC covers...…. (didn't even look)
which caused the piston to possibly kiss the valves which means the engine needs a whole rebuild.
But when i was told to buy the VTC covers it was because Nissan makes the actuator on the inside of the cover and you cant just replace the solenoids on the outside of the VTC cover you also have to replace the cover itself.
Which now im finding out if your replacing the VTC cover; you should be removing the old sprockets and chain off with it.
