So they are definitely more than hand right with loctite, I should be good right?

12 ft. lbs isn't a lot of torque to begin with. So, if you think you got them more then hand tight with loc-tite. Think you will be ok. Did you use any rtv on the gaskets?

And these are the “upgraded bolts” from concept Z
And looking at the DIY pictures it looks like they stripped on them as well.

When you say stripped the bolts. Are you talking about the allen hex socket turning inside the bolt head, or the bolt will not tighten up in the bolt hole?

If he says he can see it in the photo, I'm assuming he is referring to the bolt head and not the threads. I prefer using torx on all allen/hex bolts - they seem to round off far less often that way.

Yea it was just the Allen head of the bolt. But I did have to order new bolts for oil pan(1) timing cover(1) and cam covers (17) because some of the threads spun. It’s weird I started inspecting the bolts and a lot of them were messed up even before I started putting everything back.

Timing cover and oil pan got rtv about a 4-5mm bead. Fsm said up to 4.4.

I can’t seem to turn the crank bolt the 90 degrees after the 33ftlbs I got it about 45 degrees.

And taking car of motor mounts with everything out of the way was by far the easiest part of all of this haha

I couldn't get the full 90deg on my crank bolt either.

Sweet good to know. Since new bolts had to be ordered it’ll push this back till probably Tuesday. But it’ll give me time to install the speedhut oil pressure gauge. Any recommendations since you have the same one? I’m going to follow the diy you sent earlier.

Did you get a longer cable from the sensor to the gauge? If you didn't. You may have to splice and make the wires longer. Depending location of the gauge.

It’s about 9’ long.

That should do it.

My Z decided to start making a ticking noise when leaving a store one day. It’s never made loud valvetrain noise ever. It wasn’t on a cold start and it’s not at idle like some other posts have said. I’ve tried to research as much as I could before posting this.

The noise: it isn’t a loud rumble, it’s not a “knock” it’s more of a rhythmic loud-ish tick between 2200-4000 rpms on on throttle and stops ticking when the throttle has been let off completely no matter the rpms. I can hold the rpms steady and the noise happens.

There was 5W-30 synthetic oil in the engine unfortunately I was not running ester oil. I switched immediately to redline, and it’s been about 500 miles since the switch. The noise hasn’t gotten worse or better. I’m going to post a video of the noise soon. Power is the same and no vibrations.

There is an engine flush that’s supposed to help with a ticking noise that can occur with some of the z cars. The one I’ve seen good things about is called Xtreme clean engine flush. I thought it was only on the 300z’s but read somewhere that someone had the same issue with their 370z. The one occurrence with a 370 and multiple of the 300z’s were fixed by using the engine flush!

I meant to post the actual product before but got super busy! I haven’t tried it personally but the reviews look decent in terms of getting rid of the ticking.

Is it in one head only, or both heads?

Sounds like both but the driver seems to be the loudest.
