Broken bolt on exhaust outlet on head
silversur4 - November 6th, 2003 at 06:26 PM

Help
While changing my exhaust last weekend. I was removing the old exhaust and undoing the bolts of the head on the right hand side.
one of the bolts sheered off.
I have been able to fit the exhaust but missing one of the bolts on the right hand cylinder closest to the back. I always forget the numbers.
Any suggestions how to replace the broken bolt or should I just go to an exhaust place and get them to fix it
Can any body give me some suggestions.
Cheers
Scotty

"but missing one of the bolts on the right hand cylinder closest to the back."

i take it mean #2?

To fix properly you need to ezy out the stud. To do this with motor in the car is a pain.
Then you either put a new stud in but if the thread is stuffed then a 10mm? / 8mm stud needs to go in.
Once again in car is a pain.

What sort or car/motor is it??
If a stocker i will say i once had a pulled stud on a 1600. Was the bottom stud on #3. The worst to get to. Definitely a motor out job.
Never did. You could see the stud just loose and trapped there but it was fine. The flange didnt leak and was ok :o

What i am saying is if you CANT/WONT pull the motor now, IF you can wait till at least the clutch needs doing.......

It is a kombi Ute with a 1776. I cant pullot the motor but might take off the exhaust and see if I can fix it. It seems to back fire a when I come of the gas and I have had a look and it does leak a bit.

How do you Ezy out a stud

Thanks Barry

Hi Scott,
"Ezy out" is a brand name for a coarsely threaded, tapered, left-hand-thread pin. You drill an appropriately sized hole in the centre of your broken stud, and wind the "Ezy out" counterclockwise into this hole till it binds and hopefully allows you to wind the stud out of its thread.

Its not that easy, especially drilling the broken stud in the centre.

Another option, provided there is some of the broken stud above flush of the head, is to place a nut over the stud stub and MIG weld it to the stud and then back it out with a spanner.

This is not easy either.

Only you can judge whether it's a job for you. Me, I'm kinda clumsy so I'd take it to an exhaust place, where they tackle that kind of problem often.

I think that I will take it to an exhaust place on Saturday.
