Has anyone got some advice on the best way to undo the exhaust nuts to turbo on a td5 without the studs shearing/breaking?

Your help appreciated.

Many Thanks.

Lots of wd40 or gt85 everyday for a month

it looks a bit pricey but IMO worths every penny of it Welcome to: Loctite® Freeze & Release worked for me every time in places where others failed with the good old heating method

To me WD40 is useful as a water dispersant ,and not for rusty components.Some might disagree.
My main concern is the exhaust to turbo stud that you cannot see whilst looking into the engine compartment from above.

However I shall try all suggestions given and hope that none break.
They are after all M10 studs,so should be robust.

In the meantime I have acquired a can of plus gas so all in all so will just have to be patient and pray.

Many Thanks.
