Rounded exhaust bolts ( dump pipe )

[Limmy]

Hi Guys

Got a question. I had epic fail time trying to remove exhaust bolts underneath the car. I managed to round off one nut .

How can i get his nut off ? I have 3 to remove altogether . I tried spraying with CRC . no luck. none of these nuts are budging

You could crc , blow torch to heat them don't use a shifter on them if that's how you rounded it use a spanner or socket set. Are you planning on puting the exhaust back on??

yeah i was using socket . but it slipped. blow torch i see. i was at the Sunday market today , Guy was demonstrating a blow torch with those gas cans . Should've got one ! . also would a heat gun work ??
i'm trying to remove the dump pipe so i can get the egt gauge bung welded on.

I'm not sure if heat gun will work it might let me know if it does heat does work well on stuck nuts and bolts etc best advice is just keep going at it you'll get it eventually

Try using a 6 hex socket, did you use a 12 hex? Also apply some butane heat as you discovered already.

Spray them again then again before you quit for the night
let the crc wd40 soak in over night

gas axe... works a treat with those stubborn bolts

You could try a Metrinch socket, can work with rounded bolts.

Failing all that - go to a good tool shop and buy a nut cracker. They simply attatch to the nut and split it in half.

you are talking about the bolts at the bottom of the dump pipe if so just cut them grinder or gas axe will do if at the top behind the turbo belt a socket on if that fails it is a removable stud so it can be cut
