Just a small tip, WD40 is NOT a penetrating oil but a reasonably poor lubricant and whatever else it claims to be.
Make your own penetrating oil using 50/50 ATF / Acetone, even thinning down engine oil with diesel works but I prefer the first one.

Did try something similiar but with an allen key banged into a hole drilled into the head before it came off and some superglue . Left it overnight and turned it next day but it just broke off . I don`t have a welder but a neighbour does so may ended up trying that . Thanks

All good advice . Thank youDevonPaul wrote: ↑Fri Jan 20, 2023 11:58 am if you can part thread a nut to the remaining stud, then tack weld it. Lots of heating, spraying, and tapping the end with a small hammer when hot and cold.
I've done this in the past with bike exhaust studs.
If you end up drilling it out try and use a 90 degree bit holder and come in from underneath - that way the swarf goes away from the engine

I'm not sure welding is the answer as those bolts on the N52 engine are aluminium IIRC.

Ok well finally got it out today with the help of a neighbour and his tig welder . He welded a nut onto the bolt and we both reckon it was the heat that did it as none of the previous options worked . Anyway I can get everything back together again as I have a replacement bolt ready to go.
Thanks again for everyones input

And most importantly, you can use the bolt again.

You must admit, the middle bit of that thread looks sort of ok-ish.

You’re right, i was expecting it to be corroded but apart from a burred thread at the end it looks as though it should have unscrewed ok
