Removing air inlet concertina captive bolts

[75driver]

Any recommendations for removing the 3 captive bolts, that secure the air inlet concertina?
Mine are just spinning.😪
Tried wedging a screwdriver in from behind, but with no luck.
Do I have to remove the black steel piece that the bolts go through?

Any quick fixes once removed?

The black metal thingy that they go through is the slam panel. And I have the same problem.
The bolts on either side screw into rubber wellnuts. I bought some off ebay and it looks like the metal female thread for the bolt doesn't start until about a quarter inch down.
The one in the middle doesn't have a wellnut under it. If you go to Rimmers and find the bit that shows the turbo air intake pipe, you'll get a better idea of what it looks like under the slam panel.
As for getting them off, I'm considering raising them as high as possible then cutting them off with a hacksaw.
The wellnuts are M6x15 iirc.

First you need to pry off the air duct, using a car trim removal tool metal, use one with the widest gap.

Press down and pop the air duct off each end of the rubber grommets then the middle one.

The best way to remove the air intake is to remove the slam panel as you will have more room to remove the rubber grommets off the brass collets after removing the air intake.

Once you can access the brass collets a mole grip is your best friends and an 8mm socket. ;)

When Artic changed mine at a nano last summer he made the above procedure look so simple.

Thanks again Steve.

Can I ask what is the solution, once removed?
Refit a new rubber grommet with new brass collet?
Or is there an alternative "bodge".?

Ooooh no bodging please :D
Checked my bag, they are M6x15 wellnuts, come as a pack of 5, and then you'll need some M6x15 bolts. When I eventually get round to doing mine I will put some copper grease on, or wipe with an oily rag, to help get them off in the future ;)
Edit - but if you must bodge, how about using the sticky pads that number plates are stuck on with? Just peel one side off to stick to the pipe, top and bottom, using this to cushion the pipe so it doesn't rattle.
No idea if that would work, but I would advise to replace the bolts.

Ha....thanks😀....I used the term “bodge” quite lightly in this instance.😬

From vague memory, I did something along the lines of fitting a single strip of metal instead of the 'nuts' below. Either drilled and tapped or drilled and self tappers.

i went for brute force and ignorance.armed with a cordless drill a pair of grips and a very sharp drill bit.i simply gripped the nuts so to spk.and then drilled the heads off.then took the duct off shook out the debris .fitted new rubbers with stainless steel flange bolts.still easy to remove several years later

Yup, just had the same issue. My fix was as per the Suffolk Boy's, just drill 'em out as if they're that corroded there's nowt worth saving anyway. I 'future proofed' it by buying a new set of Well nuts and ran a light smear of contact adhesive around the top surface of each 16mm hole and a similar treatment to the underside rim of the Well nut with a matchstick, wait 5mins and bring the two together. I ran a bolt/washer in them to clamp them in place for an hour while it all set. Finished it up with some spanky stainless button head hex screws.

Was a bit skeptical as to whether the adhesive would properly bond the two different plastics in a working situation but so far it's working well, all the adhesive has to do is hold them until you've got a couple of turns in and it starts compressing/deforming into the hole, from then on it self grips the more you tighten it. It's withstood 3 removal/re-installs so I'm calling that a "fix". :-)

For the side fittings, I fitted a metal 2 plates inside the air duct with a 6mm nut brazed on each plate. For the centre fixing I fitted a metal plate under the air duct with a 6mm nut brazed on.
I made sure the metal plates could not spin and also glued them in place and then used ordinary 6mm bolts

I wedged a thick metal bar under where the fixings were mounted and got mine off. I then just clipped three of the fixings that are used on the the engine under cover. Never had any problems with them over the last 6 years.

I always use spires & screw bolts, easy to remove when ever you wish.

On this car the air duct had the modified duct done :eek: therefore it was going to be replaced with the original air duct.

Easy to remove as it was not connected to the slam panel

As you can see the rubbish brass collect and metal bolts had been left in situ:mad: using some long nosed mole grips & 8mm socket soon remove them.

Add the spire to the end of the air duct.
