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

Hi Mr Tidy . They were aluminium on the magnesium cover I believe but steel for the plastic cover Definiteley steel on mine .

That's probably why it is putting up such a fight! :roll:

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

Good to know you got there in the end!

And most importantly, you can use the bolt again.

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

I do like re using certain items but as I have a replacement bolt maybe not this time

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 :?

Tell me about it .......my neighbour has worked on loads of vehicles and race bikes and he was just as surprised . I`m glad I had someone else with me as a sanity check . Tried the new bolt today just gently winding it in and out a bit further each time and all seems to be ok .
