Hi,

Got the car jacked up at the moment and I've bought some new studs from Nissan....

but i didn't think to ask how to remove them! Oops

(my exhaust gasket is stuffed by the way, that's why I'm in there)

None of them are busted, just wanna replace 'em while I'm in there.

Do you just screw to bolts together and untwist or do you need a special tool?

Thanks guys.. :(

There is a special tool called a stud remover. They're not expensive.

But, two nuts also work. You screw two nuts on and tighten them against each other, then turn one to remove the stud. You can try the two nuts, but be very careful

I cannot stress enough. Be careful, be careful be careful.

Don't put too much force if it feels like it's not coming out. Do not break it.

If you break it, you'll feel like hitting your head on the wall, and you probably will.

Theres also a special tool called a welder......lol

Just weld your nuts to the studs, usually the residual heat will help with getting the stud out.

PS Use gallons of WD40/CRC, like Manwhore says you DON'T want to bust one.....GL

hahaha, you guys are a serious crack up.

I'll just reiterate again. DO NOT BREAK IT.

I just went through the biggest pain about a weak ago. I said to myself do not break it. Snap. I had my friend with me helping me at the time, and he was rushing me, becuase he had to go.

Now, I absolutely refuse to do a job when there is no time. just do it the next day. I thought shit, my friend has to go in 20 minutes. this is really seized. I'll just break it and get on with the job.

I didn't use any wd40/ironox/penetrene. I didn't try taping it with a hammer to loosen it. I didn't try heating it. I just cracked it with the breaker. that was the most stupid thing. snap. With a bit of care, it wouldn't have broken.

then, I rushed to use easyouts. I didn't drill the hole fully centred, since I was rushing. Then I snapped the easyout. I tried to drill, but the easyout snapped 2 drill bits. I got a bigger bit, but the easyout pushed it sideways, so I drilled a big hole next to the easyout. Snapped one massive easyout in there.

no fun. lol

I have had snapped studs before and a mechanic friend has helped remove them.

He gets one of the thick exh. manifold washers and welds it to the broken stud (he has even managed it when they are "submerged"), then welds a nut onto the washer. As said above, the residual heat from the welding helps loosen things up, along with some WD40.

He says it is a commonly used technique in exhaust shops.

when I did mine I soaked the studs in Penetr8 overnight before trying to undo them. It seemed to help, because most came out OK. A couple had already snapped off and they needed to be drilled and easy-outed.

Like Manwhore says - this is NOT a job to be rushed. Snapping a stud will annoy you but if you snap an easy-out you are in worlds of pain.

I do the same thin, but I drill one of the nuts out, remove the thread, when you do this make sure the hole is just big enough, cos then you can tap it onto the stud with a hammer. This way you don't have to hold it there when you weld it on.

    • Waaay ahead of ya....(evil laugh!!) Will show the fitment and spec details later when it isnt as rainy !
    • Thanks Dose.....    I appreciate it!!
    • I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.
    • I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.   
    • Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.
