Rocker Bolt snapped....WTF do I do now?

[RRossi]

Any advice appreciated,

was going to change my springs today, but thought, nah I will get a shop to do it as my air hose was a bit to thick to get into the spark plug holes, so I started to put back all my rockers, with my torque wrench set at 30nm as the manual states, and one just wouldnt click, so me being retarded, kept on going and SNAP, so what can I do now? ezy out?

any advice please, or do the heads have to come off?

cheers

yeah ezy out will do the job just fine just protect the rest of the open area with say glad wrap and punch a hole on on the bolt your working on so no drill shaving find there way else where and also for safty keep a vacuem close to the hole your drilling to suck up all the shavings if you know what i mean

[RRossi]

Okay so I got a kit from Auto one,

so basicly I drill into the snapped part then get the "out" bit and tap it in with a hammer and wind it out?

sounds right??

RR

[vpstroker]

yep thats it but dont drill the hole too big say try half the size if the snapped bolt first
the last thing you want to do is drill a hole the same size of the bolt then damage the thread then you cant use the standard bolt back in

[Souljah]

Do your best to drill the first hole as close to the centre of the snapped bolt as possible. Even use a centre punch to lightly mark the centre so your drill doesn't wonder close to the edge. And don't put to much force on those ezy outs. They have a bad habbit of breaking inside what your trying to get out.

[RRossi]

Woot!! after an hour of trying the bolt has come out!!!

I will go tommorow and get a few bolts from AMCAP, and then book it in some where and get the springs done, if the other bolts are a bit over tight, can I expect to break any when I start the motor?

thanks guys for your advice.

I'd suggest you check your torque wrench to see if it is still accurate.

How do you check a torque wrench, I have had my Warren & Brown wrench for many years, never broken anything but at times doing something up to the specified torque I have thought this feels too tight, ie if I had not had a torque wrench I would probably not have tightened as far.

well done, i had a snapped bolt not long ago but an easy out couldnt save me so i had to drill a hole and tap it.

A simple, cheap and pretty accurate way is to insert the square of the torque wrench (where the sockets attach) in a vice with the handle horizontal.

Now measure from the centre line out along the (horizontal) handle and set yourself a reference point.

Now hang weights from the shaft (reference point).
Torque = force x distance.
Eg. 1 Foot Pound of torque is 1 pound hung at 1 foot, Convert to suit your wrenches calibration (ie metriz, etc).

You set the wrench, then load weights until it clicks, I use a wire loop with a hook and add sinkers and washers, then weigh them on kitchen scales.

I actually built my own in the second year of my apprenticeship, still have it and its still very accurate, certainly learnt how to use a mill and a lathe!.
