I'm being lazy but hoping someone might know the nut size for the exhaust manifold studs on a TD42?

I am not sure if It's an M10 x 1.25 or M10 x 1.5???

Cheers for any help!

just be careful as a lot of the older cars have had the front and rear studs on cylinders 1 and 6 drilled out and replaced with large stud bolts as they have been stripped form over tightening warped manifolds I learn't the hard way after putting copper gasket paste on the turbo manifold and then realizing I had to drill it out and the gasket.

I just replaced four of mine that sheared off. I can't remember the block thread pitch but I'm sure it was M10x1.5 . I couldn't find studs to match both inner/outer so the outside thread pitch was definitely M10x1.25. I just ended up using different nuts on the new ones.

Jesse, there is a metric nut, bolt and pin distributor in Surrey.

Affirmative on the outside thread Andy..M10x1.25. Just snapped one on mine yesterday on an attemp to mount the pyro probe to the manifold..very niceeeeeee
