Rounded exhaust bolts ( dump pipe )

[Limmy]

Ended getting the rounded nut off . Thanks for advice guys .

I ended up trying .
- CRC spray
- Heat from blow torch
- use a 6 sided socket , instead of the star one which rounded it
- Also used my leg for strength

BUT...#*$!.... i ended up snapping the "bolt" that goes through the dump pipe bracket to the block . I'm having the worst time drilling it out . I snapped plenty of drill bits. I think it will take a lot of time and patience.
IM HAVING THE BEST LUCK !!!
So far i've tried
Drilling fast
Drilling slow
using COBALT drill bit now . I still haven't drilled in far enough for EASY-OUT to go in yet . I've ordered left handed drill bit on ebay . any experinced my problem ? Does anyone know how LONG this bolt is ? i'm drilled in about 5 mm

Limmy ,

Bolt is only about 12mm thread length

Check the depth of the hole beside it for reference

It looks similar to the bolt on the heat shield. Which is bout 12mm.

Limmy,

I only just took it off to install the Beaudesert Exhaust system, which came with its own bolt for the dump pipe mounting bracket, as it is a lot thicker.

I have the original bolt, but it is in a box with all the other bolts, but I seem to recall around 12 mm sticking out of the bracket ( It came from Beaudesert, with the bolt taped in the hole so it can't be too long, otherwise it would easily get damaged in transit.

cool awesome thanks . I still haven't drilled through the bolt . I will definately give it a good go tommorrow when i knock off work. I ended up cable tieing the trigger of my drill so it holds the slow rpm drill. i still managed to break my cobalt drill bits.

Careful that slow rpm don't kill/cook the drill.

What about welding a plate onto the dump pipe bracket and bolt up to the unused threaded hole to the right of the broken bolt?

[Limmy]

That is a good idea Mudski . if all fails , that will be an option

i used some high speed drill bits today and high speed. very good progress . i can see shavings . i'll buy some more of those bits as i snapped them. drilling slow didn't really work for me

Dip the drill bits in some oil so you don't blunt them so quickly and it will keep the heat down a little too. Would be quicker to weld a new plate I reckon. If you have a welder that is.
