I used a corded impact to no avail with a heat gun. I think my problem wasn’t enough heat but this guy from work let me borrow a SnapOn 1/2” breaker bar and we got it to break free finally. So gotta back it up for the night I can continue on it Wednesday. Wednesday I plan on getting to the gaskets and we will know from there

Since you put heat on the damper bolt. You may want to change the front seal.

Please don’t bash me this forum and workin on this car is how I learn and fulfill the empty void of not working on cars when I was young. What do you mean front seal? I don’t see a seal on the bolt or or damper. I see the plate looking thing on the bolt? The heat gun is a AutoZone special it says it can reach to almost 932 degrees.

And I have an update!!!! Obviously I’m not the fastest mechanic but I finally got the left cam cover off. and Found something, sorry I don’t know why the image came in sideways.

I'm not bashing you. Just giving you a heads up. :tup: The front seal is the round seal that the damper slides into. It's located in the front cover. When you apply heat to the damper. It may transfer into the seal. Making it hard and brittle and causing a leak. Don't ask me how I know. :rofl2:

In the picture. Do I spy a piece of gasket hanging down in the back?

Jordan12berg 09-13-2018 05:21 AM

Ok well I read that I had to replace the crank bolt too, so when I head to the only Nissan dealer here in Atlanta greater area that has one I’ll make sure that they have that to.
And I knew you were bashing haha.

I also noticed that now might be a good time to throw in some solid motor mounts....

Is part number 13510-31U10 what I need? I’m already swimming in cam gaskets, o rings, and gallery gaskets so what’s one more?!

And you are correct that brown piece hanging outside of it’s home is the gasket

Spooler 09-13-2018 02:47 PM

Yeap, Galley gasket has failed.

Jordan12berg 09-14-2018 06:51 PM

Any pro tips on this oil pan? I can’t even get a razor blade to the glue

Rusty 09-14-2018 07:39 PM

All the bolts out? If so, put one back on each side. Just a couple of threads screwed in. When the pan pops loose. This keeps the pan in place and not making a mess of things.

I've used a wood chisel at the split line and tapped it in with a hammer. After cleaning up the split line. If there is any marks or gouges. I use a fine file to file down the raised area. Just be careful.

Jordan12berg 09-14-2018 08:01 PM

I had all the screws removed originally, I can put a few screws in. The problem is I I have even but a razor blade on a handle and slightly tapped it in and It won’t even let the razor in. It’s so tight at the split line.

This is what I’m working with

Jordan12berg 09-14-2018 08:56 PM

Got it! :happydance:
And 125xxx miles, blown gasket, still no metal shavings at the bottom of the pan or the magnetic plug :tup:

Jordan12berg 09-17-2018 08:11 PM

Great these bolts for the galley gaskets, the 4mm hex bolts, are starting to strip before I get them to 12ftlbs. I put loctite on them.

Rusty 09-17-2018 08:24 PM

You putting it back together again? How bad was the gaskets?

Yeah, sometimes those small bolts don't have enough head on them for a good bite.

Jordan12berg 09-17-2018 08:30 PM

Yea finally, they were pretty much exploded on the sideways Y piece.

So my torque wrench can’t even torque down to 12 before they strip. It’s close but it won’t click before they give. I got loctite on them am I going to be ok?

Is the torque wrench in in.lbs or ft.lbs? A 4mm diameter would be in, in.lbs. If your torque wrench is in, ft lbs. And you are torquing to that. 12 ft.lbs is 144 in.lbs. :eek:

Jordan12berg 09-18-2018 02:23 PM

Haha torque wrench is in ft lbs. I have a hex tool set with a 3/8 connection set I was using.
But yea I followed this http://www.the370z.com/diy-section-d...ml#post3735619 #9 says 12 ft lbs and I dug up all bolt orders and tq specs in the fsm.

I read the thread. Yeah, it says 12 ft.lbs. I see where it's a 4mm allen. Not a 4mm diameter bolt. Big difference between the 2.

Spooler 09-18-2018 06:54 PM

Doesn't someone make upgraded bolts that can be torqued properly? I am not sure who makes them, that's what is going on my car.
Do a search, it is on here somewhere. The bolts and gaskets are upgraded.

It's a steel bolt threading into aluminum hole. Don't think the issue is with the bolt, it's with the hole. If this is happening. The fix would be to heli-coil the hole.

Pic from the DIY thread.

Jordan12berg 09-18-2018 09:44 PM

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

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

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?

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?

JARblue 09-19-2018 08:18 AM

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.

Jordan12berg 09-21-2018 02:49 PM

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.

Jordan12berg 09-21-2018 02:50 PM

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.

Jordan12berg 09-22-2018 08:03 AM

It’s about 9’ long.

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?

Jordan12berg 09-27-2018 05:03 AM

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

SG4247 09-27-2018 06:10 PM

And thats why it pays to do a proper inspection, generally it saves time and cash.

Ask me how I know...

I was scared of this after fixing the gaskets. Still making noise. With the gasket blown, and losing oil pressure. The lack of oil pressure caused some damage in the heads. I was hoping it would quiet down with oil pressure restored. Is it quieter now then before you fixed the gaskets?

About the same. It’s also in my garage so it’s all kinds of noises in there. After work today I don’t have my second job so I’ll be getting it out for it’s first test drive. I’ll let y’all know how it is after that. And I’ll get the gauge wired up today.

Speaking of which, what did you tap the white wire into? I know it’s the “light dimming” wire.

Ha well at least I had fun doing it overall. If it ends up being a lifter or something it is what it is.
And to be honest my skills aren’t good enough to properly check lifter clearance. At least they aren’t right now they may have to get to that point.

I got the dimmer switch with the gauges. I have a separate switch to dim. You would have to ask someone else to see where to tap.
