exaust manifold bolt sheered

[kyepan]

hi there,

I have noticed a bolt has sheered on the exaust manifold (far right hand side), how do i go about gaining access in front. and how do i remove it..

have herd people mentioning drilling and tapping in the past. is that correct.

many thanks

JB

Depends on how much of the thread is visible above the block ? If there is a bit, you could try mole grips, or file some flats on it and use a spanner.

If it is flush with the block, you will need a screw extractor kit. Basically you just drill a hole in the middle of the bolt, and the extracter screws into the middle ( it has a left hand thread ). Then when it is tight, you should be able to spanner the extractor and the bolt will come out ( in theory )

The other alternative like you said above is to completely drill the bolt out and re-tap it. Have to be careful though, as it usually leaves a 'sloppy' hole ( oo-er missus )

thanks ross, i think we will have to drill the bolt and use the extractor kit, cause its sheered below the surface. thanks for your help

Good luck with the extractor they always shear on me.

Is there something up with that stud ? On both my engines that particular one is broken. :?

another way is the put a few blobs of weld on the end of the stud then weld a nut to that and wind out the stud normally (after letting stud cool down a while)
