head gasket

[Cheeze]

was reading my hanyes manuel there it say to replace the cylinder head bolts when your doing the head gasket, is this true?

[Dicko]

yes they are stretch bolts and can only be used once!!!

make sure you use a genuine vuaxhall gasket+bolts!

[James B]

wot kinda damage could it do to use same ones again

[RICKY132]

wont do any damage,used head bolts more than once on several occasions.however it isnt advised i guess,as for genuine parts ,ive never bought any and had no probs wiv gaskets

[Aragorn]

to stop any requirements for retorquing the headbolts are essensially overtightened and they then stretch slightly so they are applying the correct torque

the problem u get is if u try to reuse them they wont stretch the same way so your torque settings will be out and you could crack the head or summat nasty like that

[Cheese]

Or you could snap part of the bolt off in the block! :?

[Dicko]

yup, they stretch quite a lot. you wont get the correct torque setting and a chance they will snap. iv used non vuax bolts before and a head snapped off 1 as i was putting it in. also iv used a non gen vuax gasket and it only lasted 500 miles before it started leaking
