⚠️ Common Signs of Failure

• Manifold nut backing off repeatedly at the same position
• Blow or hiss at the manifold joint where clamp load has been lost
• Exposed thread corroded so a nut will no longer run down it
• Stud sheared level with the manifold or head face
• Female thread found stripped or pulled on removal

🛠️ Service Notes

• Manifold studs corrode and seize with heat cycling - renew the stud and nut together rather than fighting an old thread
• Check the female thread in the casting before fitting, as a pulled stud usually means the parent thread needs repair
