:bang: i'm pissed off at my self now because i just managed to snap a bolt off while changing camshafts, now i think i will have to buy anyother head :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang: :bang:

Doh!

what bolt was it?got pics?

this one but on the top camshaft

its snapped down the hole so i cant retreive it

does it mean i need another head? or can a machenist recover it?

can be extracted by an engineers shop easily i would say. why are yu changing cams? is it due to the timing issue?

Click to expand...

exactly

In the engineering trade there is a tool we call an easy out you drill a pilot hole in the stump of the bolt and screw the tool in its left hand threaded so that inturn removes the bolt but even if you can get your hands on one and unless your capeable take it to a general engineering shop it will take them minuites to remove

I have never managed to get an eze-out to work. All the bolts I've got stuck on had the thread siezed too badly in the nut, just end up making a mess.

Best take it to the machine shop, but make sure you put tape over the head face so it doesn't get marked.

could drill it and re-tap it, thats what we'd do at my work but i dunno whether you'd trust your self doing that...

best leave it to an engineering shop

At my fathers workshop I would probably just drill out the hole in stages and re-thread until the debris was clear of the threads. To get it out with an eaze-out, you need to go as close to possible without touching the existing threads (two sizes down to be safe) before you would get any kind of action out of it. I would send it to an enginees workshop and do as suggested by taping the faces to prevent scratching. Or if you have a pillar drill and a dutch clamp, clamp it in there, center with the hole as do as i would be drilling it out and tapping with a new thread to match, if you cock up, thread it to next size up with torque bolts.

This is just what I would do lol,
