Flywheel bolts

[voucht]

Hi,
In the Ford Sierra repair manual, they say that if the flywheel bolts are removed, they should be changed to new ones. I just removed the once, and now, I've bolted them back in place with Loctite Thread Locker Blue at the right tightening torque. Do I really have to put new ones? what are the risks?
Thanks.

Thanks for the reply.

The Haynes book said the same for the Pinto engine. I haven't heard many bad stories about flywheel bolts suddenly failing but did not want to take the chance so bought a set of new ARP flywheel bolts.

As Chris said, for £14 you can buy ARP as let's be honest your going to rev the nuts off it when your on the road

Thank you fro the replies

Yes, you are right, for the price, why bothering ? But it is always a mess to find these kinds of "special" items here for me, so if I could have avoid such researches, I would.

And I guess if I go directly to Ford, it will be £14... for 1 bolt

But I will definitely find them and put new ones, saving on this is not worth the risk.

Thanks again.

Defo not Sylvain,if you think about it depending on rotation of the flywheel this may come through the bell housing and chop your legs off as its fairly close to them.

Cost you £23 + postage
The other idea is to set a rev limit to manufacturers engine spec
as they won't break at that
Another cheaper idea is to fit a dowl or 2 this will stop shear on the bolts
Some cranks already have one hole ready

Thank you for the last comments

Yes, I'll definitely change them.

I still don't really understand why they can stay forever on the flywheel without being changed if you don't touch them, but once they have been unscrewed, they are likely to brake (?) so need to be changed. I guess removing them stresses the metal some how, but...

So, isn't it the same with the rear axle bolts? It should be, because to me they get the same shear force as the flywheel bolts, no?
