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.

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.

      I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.

      @Dose Pipe Sutututu I read your replies RE: R35 GTR MAFs, any ideal spots to put on? Obviously will need the adapter plate. Will be having a cross over intercooler fitted shortly, would putting it a bit before the TB be okay?
