Cylinder Head Refurbishment
Cylinder head refurbishment for damaged, worn or overheated cylinder heads, with advice based on inspection rather than guesswork. Apexx Engines can support private customers, garages and trade customers across the UK with specialist head work.
What is cylinder head refurbishment?
Cylinder head refurbishment is the process of cleaning, inspecting and restoring a cylinder head so it can seal and operate correctly again. Depending on the condition, this may include pressure testing, skimming, valve work, guide or seal replacement and advice on whether repair or replacement is the better route.
Who this service is suitable for
Apexx Engines gives practical advice before work starts, because the right repair depends on the engine, the fault, the condition of the parts and the customer’s intended use.
Head gasket failure
Often required after overheating, coolant loss or head gasket failure where the head needs checking before refitting.
Valve or sealing issues
Useful when poor compression, misfires, valve damage or valve seat wear suggest the cylinder head needs specialist attention.
Engine rebuild support
Commonly carried out as part of a wider rebuild so the head can be inspected and prepared before the engine goes back together.
What the work may include
The exact refurbishment route depends on the cylinder head material, design, damage, previous machining history and the customer’s intended repair plan.
- Cleaning and visual inspection
- Pressure testing where suitable
- Cylinder head skimming where the surface needs correction
- Valve inspection, seat work and related advice
- Valve stem seal, guide or spring checks where required
- Clear communication if the head is too damaged or previously machined beyond a safe limit
How the process works
The aim is to keep the repair route clear, avoid unnecessary work and explain any additional findings before the job changes.

Frequently asked questions about cylinder head refurbishment
Can every cylinder head be refurbished?
No. Some cylinder heads are too cracked, warped, corroded or previously machined to be repaired safely. Inspection confirms whether refurbishment is suitable.
Is skimming included in cylinder head refurbishment?
Skimming may be included where the head face needs correction, but it depends on the inspection result and whether the head is within safe machining limits.
Do you pressure test cylinder heads?
Where suitable, pressure testing may be recommended to check for cracks or leaks before a head is refitted.
Can garages send removed cylinder heads to you?
Yes. Garages and trade customers across the UK can send removed cylinder heads for inspection, machining or refurbishment.
What causes cylinder head damage?
Common causes include overheating, head gasket failure, timing failure, coolant contamination, poor maintenance and long-term wear.
