And a billion more cans of WD40 or similar...
Yep give them a good spray and leave them overnight . Before applying twisting torque give them a good tap end on with a hammer. I call the extractor things ezy-outs which may or may not be a brand name. Use a small drill to make a hole as central as possible and then enlarge the hole before tapping in the extractor tool. Not a nice job. Good luck.

I can think of much better stuff to have in cans.lol

A local guy came to see me last night. He is going to fix. He has a special kit that uses left hand drill bits so th stud remnants wont tighten as you drill. He said in a lot of cases the stud bit comes out while drilling.

left handed drill bits sound good.. i want some

im upgrading my turb to a high flow.. swapped 2 of my mountain bikes for it.. was thinking of doing it myself but it could turn into a nightmare so might leave it to the pros.. hope all ends up well for u.. sourced yourself a new turb yet?

Sorry to hear you're having such a hard time of it... my old studs all came out pretty easy with just a lock-nut and ratchet. They look near new. I was beginning to wonder if there was anything to this stud problem... but sounds like you have the proof. Taking any pics along the way?

Actually it transpired there was SFA wrong with the turbo but I have got a spare JIC. I"m takink pics all the way. When saga is over will post all.

Incidently, what are the best type of studs, I will be replacing all of them.

$2-3 at a guess

one of the traders here at SAU seems to be getting good prices on gaskets etc in the FS section

Damn, wish I knew that before I paid a couple hundred for gaskets ;)

Yeah I used genuine nissan ones; I have a picture of the packet around here somewhere... they cost me ~$40 for a dozen I think? Which is the absolute maximum it should cost you really. There's nothing special about them; just mild steel although they do have some fancy high-temp coating. But the ones I took out were at least 110,000 K's old and they looked near new (just a little duller) so yeah put them in with some nickel-based high-temperature anti-sieze anti-bind compound (a tiny tiny bit on the end threads of the stud) when you put them in the block and they should be fine for at least another 100,000K's.

Here we are... genuine Nissan nuts (conical type locking):

...and the genuine Nissan studs & hi-temp anti-sieze/bind compound I used on the studs:

post-32445-1226402206_thumb.jpg

Nuts cost me ~$21 for a dozen (:()

Studs cost me ~$50 for a dozen ( :domokun: ) so I was had a little there... but they were just down the road and it was convenience factor :) Now studs are done :P

btw, spoke to the turbo guy and the first thing he recommended was to change out all old studs if possible and re-fit exhaust manifold after checking for cracks; which apparently are usually small and white and often seen running through the pale blue/grey sections of the exhaust manifold (which are where it has become really hot).

You can see a few of these blueish-grey areas here:

...fairly obvious where they are eh :)

Good luck all :(

PS Gee u get some crud building up in the exhaust ports...

Not knowing which valves are open or closed means not knowing which cylinders the stuff will fall straight into; I had a bit of a go with the small brass-bristled brush which is why you can see some of it chipped away, but I didn't want to go too far in over the valves. I'm just hoping that using good fuel (ie. Ultimate or VPower) will keep it clean...

It doesn't matter if you get UCC in the cylinders, it's designed to burn off if it gets into the combustion chambers - you'll find that the car will blow a shitload of white smoke for about 10secs but it'll clear up after.

I wonder if you could spray some upper cylinder cleaner in there and use a toothbrush to clean them out?

Takers?

Tooth brush? Were talking cast iron here - get one of those wire brushes you put in a drill and give it heaps.

That's what I used to clean just inside the ports... but I was too worried about debris/bits of metal bristles getting in the cylinders to go any deeper

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
