What Does Reconditioning a Cylinder Head Mean?

Cylinder head reconditioning is a critical process for restoring a vehicle’s engine performance. But what exactly does it involve?

The Reconditioning Process

Reconditioning a cylinder head means restoring it to near-new condition through a series of specialized steps:

• Cleaning: Removing carbon deposits, oil, and grime using chemical baths or ultrasonic cleaners.  At AHS we use a combination of spin wash, pressure washing and sonic cleaning to remove all contaminants.
• Inspection: Checking for cracks, warpage, or valve seat damage using pressure testing and precision measurements. At All Head Services, we utilise the latest in hardness testing technology to ensure the cylinder head is sound.
• Machining: Resurfacing the head to ensure a flat mating surface, using our precision surfacing machines and mills.
• Valve Work: Replacing or regrinding valves, seats, and guides to restore proper sealing and airflow.
• Assembly: Installing new seals, springs, and components to meet OEM specs.

This process is common for vehicles like Ford Rangers or Toyota HiLuxes, where cylinder heads endure high stress from heavy use.

Why It Matters

A reconditioned cylinder head improves engine compression, fuel efficiency, and power, saving mechanics and their clients from costly full engine replacements. It’s especially vital for performance builds or vintage restorations where OEM parts are scarce.

When to Recondition

Mechanics should consider reconditioning when a cylinder head shows:

• Warping from overheating
• Leaking valves causing poor compression
• Cracks or corrosion from age or heavy use
