Going to be replacing the throttle body on my friends 1.3 MPi tomorrow, but i know for a fact the torx head bolts holding the thing on are FUBARED and nothing will grip em.

given the design of the throttle housing it precludes using a hacksaw to chop the tops of em off, and i dont like the idea of applying heat in an area that likely to have petrol vapour / pooling.

Is it hammer / chisel time? im not worried about mashing the throttle housing as it will be replaced, and i got four new bolts + a gasket coming.

any other ideas welcome

Can you get a multipoint socket bashed over it, we've done that in the past. Being multi point ones, like 12 point, they spread the load when trying to undo tight bolts.

do you literally mean hammer a "almost fits over the bolt head" cheapie socket on it? good idea! will give it a go!

any other suggestions welcome

That's it Tried and tested

It's surprising what can be achieved with mole grips and a suitable supply of frustrated rage, but a rounded-off Torx head is like an open invitation for a drill bit

Yeah, I'd be thinking drill, just take the head off and then you can pop the TB off, and once suitably soaked/heated mole the threads out of the manifold.

If you kill the manifold I have a bare one here for sale... £10. :p

i would try whacking it with a hammer and drift really hard before trying to undo them

i will let everyone know how it goes when i do the job, parts havent turned up yet :( hopefully tomorrow
