Are you sure they're a torq? I thought they were splined.

T 55 I think?
Phoned the local ramblers club today, but the bloke who answered just
went on and on.

If memory serves, the later ones were torx headed to identify them as allegedly stretch bolts, so check the lengths when out and clean. BUT I could be
wrong.

IIRC the early ones were splined and not stretch bolts, allegedly safe to reuse.
The later bolts were Torx and stretch so need replacing, T55 sounds the right size. Note the tightening sequence, which calls for something like
torquing down in stages then another 90 deg after that.
Haynes manual has all the info.

Agree T55. I would suggest that if you need to buy one you get a one piece Impact one. They need a lot of grunt and the std ones I think are really
not up to it. This is the one I have, and been no probs.

I bought mine from the local spares shop for the Pinto head bolts and they had replacement bolts at about £1 each as well. The kit was a couple of
sockets for head and tensioner bolts and it did the job.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

prices. Get mine for Matt Lewis.

My mistake. It's a long time since I worked on one.

That so called stretch bolts need replacing every time is a fallacy.
They do deform into the lower endof the plastic range but this doesn’t weaken the bolts in fact it actually increases the elastic limit of the
bolt and dosen't effect the UTS of the bolt. Provided the bolts have not been grossly over tightened they will survive several tightening
cycles without causing any concern.

What BT said. SAAB recommend a slackening and retightening cycle to stop/prevent oil leaking from the cylinder head.
