MA10 Head Bolts

[Novasteve]

As some of you may know, the cambelt went on my 1984 K10, got everything ready to re-fit the head sunday but the bolts ive ordered are wrong!

Got a set of 10 M10 x 1.5 x 146mm bolts as thats what came up when I gave the motor factors the reg number butit turns out the bolts I removed are 5 x 146mm and 5 x 114mm

No other motor factors stock the different lengths I need, ive spoke to a good mate and he thinks that as the car didn't overheat or do any major damage, the bolts will be ok to use again. I'm a bit sceptical as i've always been told not to re-use them.

Any thoughts?

What about somewhere like Halfords of B&Q?

MA,s or CG,s dont use stretchbolts steve, re-use them as many times as you want (i certainly have )

 

[Novasteve]

Oh really? I though all head bolts were disposable, but then im no mechanic!

I'm more baffled that no one stocks my specific bolts, everyone just does 10 the same length!!

They're different lengths I'm sure mine are all the same?

never... the longer ones (6 of 10) are at the ones IN the head (at the camshaft) and the shorter ones (the other 4) are the ones between the spark plugs.

Ah right didn't pay attention that will help me put it back together lol

 

[Novasteve]

Thanks for the help guys (Y)

yeah i think the ones on the front of the block are shorter

 

[Novasteve]

Yep they were, all sorted now and she's up and running again, we were surprised that we didnt have to tighten them that much.

 

[RTLkyuubi]

If the tightening procedure includes degrees as well as a torque figure then theyre strech bolts. but if its just a tightening torque then non strech and reusable.

 

[Novasteve]

Nope, no degrees, just two stages

nice one glad to hear shes up and running again mate (Y)
