Which bolts are stretch bolt on a Duratec?
Head bolts are but what else?

Flywheel?
cam bolts?
front pulley?

Thanks
Mike

or the location of a build manual would be good....

Generally the head bolts , most change the crank ones for ARP ones as they are stronger

I have a build manual from Ford/Mazda U2U me your email I can send it to you

Assume any bolt for which angular tightening procedure is specified a "stretch bolt", ie a bolt that is tighten into the plastic deformation region of the stress-strain graph.

A hold load of myths surround stretch bolts, but as a roll of thumb any bolt that is subject to fatigue should be replaced if the engine is going to be used for anything other than shopping. Although manufacturers generally recommend new bolts, head bolts are generally safe to re-use at least once.

Based on a quick think (all single use except the Girdle):

- Cylinder head
- Crank pulley
- Girdle - max. three use
- Big end (IIRC)
- Flywheel

As others have said have check through the assembly chart for angular tightening.

Now on my second Duratec build (for a second car) and on a budget I replace the following with ARP:

- Big end
- Crank pulley
- Flywheel
