dont get you... has the stud snapped clean at the face of the head, or is there enought to get a couple of bolts on and locked?

Ok... think i know what you are saying now... re read!

Yes, just put one nut on, then a 2nd and tighten them against each other and then use the inner one to unsrew thes stud.

Drill Bit - a decent quality drill bit, smaller than the bolt... a few mm smaller to start. Best with a pillar drill to get it straight (if you can).

Tap and die - use the same size/thread as the bolt was

Measure distance on a hoel without a snapped bolt. Use a depth gauge on the drill


thansk that cleared a lot up bud :thumbs:

Well some of you may know it isnt my week and last night i snapped a exhaust manifold stud flush with the head (well little bit in the head tbh)

Well rather then take it to a garage have decided to tackle it myself (learning exp and all that and try and save some cash)

am looking at buying a tap and die kit from wilco my questions are these.

What kind of drill bit do i need to drill out the old one and what size?
then what bit do i use in the tap and die kit (comes in various sizes will get a link up in a min if needs be)

i know ill have to get a stud n nut from vauxhall main dealer..

but how far do i have to drill in the head?

thanks for any advice :thumbs:

cheers
