Removing Broken Turbo Manifold Stud

[tridentt150v]

keep at it with the welding trick, works well. A stick welder will get into the nut recess better if you can borrow one.

I'd be bl00dy careful using a breaker bar around cast manifolds, your liable to fracture the manifold. Cast iron can be a brittle item.

I keep snapping off the weld. I think I am going to call the stud remver bloke. I guess I could just drill the whole stud, since I think it is sealed - Ccouldnt feel the stud come through the other side).. I.e. the metal fillings won't go anywhere

So when you guys put in new studs do you use the double nut trick then nip them up just a little..or do you torque them up close to the torque of the nut to go one them?

Actually I think you dont really want to tighten them up too much since you sill start cutting the thread oin the shank.

The nut will tighten it anyway I guess.

Highly recomend Threadman. He is in Mona Vale.

He drilled it out and put a helicoil in since it was seized that bad.

So is the proper way to only tighten the stud finger tight?

Hey guys fun thread. Whenever I do anything with any type of thread thats going to take a decent amount of torque I always use some sort of lube- moly grease on stuff that doesn't cop too much heat and copper grease on exhaust nuts and bolts and this is a perfect example why, so frustrating.

Instead of paying the thread repair bloke $100+ try and take the whole manifold off and get at it with a drill then tap an allen key into the hole and wind it out using the end of a ring spanner to get a bit of leverage on the little bugger. if the allen key slips mig it in!!

Good luck man.

p.s as long as the stud has enough threads in to the manifold it doesn't really matter how tight you put it in. the tension on the nuts act to lock it in just as long as the nut doesn't bottom out on the part of the stud without threads.

I paid the thread bloke under $100 which saved me taking the manifold off (just put new gasket on 3 months ago)...

I should have put new turbo manifold studs in then!! One of the threads wasnt pefect on the turbo thread and it seemed to seize even more ...what a c--t

All good now. Threadman is a top bloke. He reckons he gets heaps of skylne guys..one of the most common cars with broken studs hahah
