Diesel - Injectors
These ideally require a special (deep and thin walled) 27mm socket to remove and refit
They are torqued to 70 Nm (51 ft-lb )
SimonBaxter: DO NOT SKIMP ON THE FLAME TRAPS or your injectors won't last 2 minutes
Tighten injector pipes to 25 Nm (18 ft-lb), ensure the union are hand tightened first so they are not cross-threaded or under undue stress from the pipes (bent)
Make sure that the (anti-vibration) pipe support clamps are replaced and fit well.
