snapped head bolt

[Vausey_Nova_Knotla]

Right i did my head gasket, but wile tightening it back up the 3rd bolt from the back of the head snapped.

(Borin bit)
now ive tried my best to get it out but it seems the bolt has flaired wile it snaped and its getting cought on somthing...


Now am i write in thinking i cant run it like this as it will just go again? and will i have to purchase a new head gasket? or could i use the new one i put on?

its a head off job.

the gasket might survive, but you must never, ever reuse stretch bolts...

if you bought a head gasket set, just re order a head gasket on its own, when you get the new bolts.

cheers mowgli, had a feeling it was going to be that:/ also on this note you dont put any gasket sealer on it do you? i thought they sealed them selfs? thanks rob

How tight did you do them up originally then?

Just with wratchet and when i checked with torx it was 145nm i was told 210nm and 90 degree turn?

[WBC]

145nm is fook off tight mate,...

Wouldnt be doing a HG that tight..

[mowgli]

isn't it more like 25nm +60+60+30????

Have you got a Haynes manual ? If not get one

i worked at motosave for a brief period,so must mean im a monkey:roll:
by the sound of your nova building buddy it sounds like you need to buy one already built for you,im presuming this is the paintrollered nova you have converted?
buy a haynes manual

[Steve0011]

buy a haynes manual

or at the very least, asked the question here :(

little wonder the bolt snapped, torque was allmost 6 times what the haynes says :eek:

i would consider getting a new gasket as well, the last one will be crushed to death :( oh yes, new bolts ;)

edit to say your tightening method is flawed, tighten from the start with the torque wrench, NOT with a ratchet and finish off the the torque wrench

Yes thats correct and no its just i assumed with them Working in a garage they would no better... And maybe thats the case but you also could be a vgood mechanic, obviously the Motosave mechanics round my way are Monkeys. or just gave me wrong figures on perpous. and i preffer a challage tbh would rather not purchase one already done..

Any way im not getting into a debate/argument just would like some figures.. and help. thanks

1.2 to 1.6 engines 25nm then 60 60 60 degrees

1.8 and 2.0 25nm then 90 90 90

sequence is


10 - 6 - 2 - 3 - 7
