Changing mani studs - Saxperience

Prickle^p · 6th September 2012, 09:21

Ive been told id need a extractor and ive been told pliers will get then out no bother

pigs fly dont they..

Is it worth changing these when putting a new mani on? i mean they arnt exactly pocket change @ £29.99 from spoox/gmc (to me).

I like the copper? coloured nuts off one site from Spoox.

Could someone please link me to those nuts separatly? or the size of them so i can search?

I got some 12.9 grade ones from somewhere :/
Silver ones anyway, took the first three studs out
Working left to right, top row
Got to the fourth and it snapped parallel to the manifold face :@ haven't got that out or done the bottom row yet! I used the two nut strategy on them

2 nuts allow the studs to be reused...

An extractor usually fucks them up...

So the studs are ok to use again.. no point in wasting money/pos failing to change them..

This is what i wanted to avoid. It obviously doesnt happen to everyone but knowing my luck *snap on one or 2 leaving me

on what to do.

I think i might be easier changing the nuts. I just need to find a link to some like those copper coloured ones.

I was the same and thought I was doing well too! The stud was nearly out, but snapped right at the face :@
Yeah I was fully removing studs and nuts, for Allen key headed bolts, slightly different to what you're doing, but a similar task nontheless

The Allen key nut ones could be a pain too, esp if they start rounding off.

Had that issue with £27 droplink. Never again if i can help it.

When I got the bolts, I found an exact allen key for them, gentle use means no rounding

the studs are a nightmare underneath!
Don't start on suspension!

Ah it will look alright buddy.

Lol some parts will be changed yeah. It isnt oem anyway, i have couple parts on the car that oem anyway. Exhaust etc. Exterior wise it stays as it is.

I think the mani will tie in nicely as the bay is personally.

The nuts are just normal "k nuts"

Most nut and bolt places do them :-)

Cheers mate.

edit; is it just 13mm? whats exact detail?

Prickle^p · 6th September 2012, 10:08

you say 'k nut' 13mm? whats the exact size? ive smashed googled and it brings up loads? do i just guess this?

im grateful for half of the info but would like the rest of it.

In my opinion you will be better with a 23mm m8 stainless bolt rather than a stud and nut. The copper nuts won't stay copper coloured for long and the studs will rust. They are also cheaper at the main dealers than spooks. The size you want is .... Manifold Stud - M8x1.25 - Inner thread 15mm, Blank 6mm, Outer thread 32mm - x10
Manifold Nut - M8x1.25 - x10 (No washer needed)

Also when removing the old studs spray them with wd40 and warm the engine a little will help you remove them. The 2 nut method seems to work well.

i removed mine a while back on a 2003vtr to swap for stainless bolts. nearly all nuts were rounded by the time i had last few studs to remove ended up with mole grips on them as spanners just werent gripping.
and once i fitted the bolts you will find its alot easier to fit a aftermarket mani and the studs and nuts dont leave alot of room so you end up tightening one bolt for what seems days
