Chipped td5 snapping studs on manifold

(1/2) > >>

disco2 td5:
I know the way to fix is machine out the webs on the manifold and replace the studs with better ones but I'm wondering if there's enough metal to drill out to m10 studs and fit them instead of 8mm thanks

G30RGE:
Not sure on drilling out but there is a stud conversion available (can't remember where)

Is your's remapped or a plug in box?
The autologic remap runs quite hot which does not help the warping.
I replaced mine with a ceramic coated one :-)

disco2 td5:
It's a plug on box
Also running about 25 psi boost
D44 centre box removal pipe
D44 side exit exhaust
Erg removal kit

I only notised it had broke a stud because it were ontop of the engine cover

What I were thinkin of doin were drilling out to 10 mm then using 10 mm bolts with spring washers also grinding away the webs and skimming the manifold

big tim:
I belive its J.E engineering that does the studs and bobbins for A TD5 exhaust manifold

disco2 td5:
I've seen them about and I've wondered what putting bobbings and longer studs does
The only thing I thought was it gave it more stud to take up the stretching forces
