Understanding Head Gasket Repairs
A head gasket plays a critical role in your engine’s operation — sealing the combustion chamber and maintaining pressure while keeping oil and coolant separate. When it fails, it can lead to serious engine damage, poor performance, and costly repairs if not caught early.
At Approved Engines in Sudbury, Suffolk, we specialise in diagnosing and repairing head gasket issues — from minor leaks to full engine rebuilds.
What Causes Head Gasket Failure?
Head gasket failure is most commonly caused by engine overheating, but it can also occur due to:
- Poor engine maintenance
- A warped or cracked cylinder head
- Coolant leaks or blockages
- Prolonged driving with low coolant levels
Once compromised, the gasket can no longer seal effectively, leading to major issues like oil and coolant mixing or loss of compression.
Common Signs You May Need a Head Gasket Repair
Not sure if your vehicle has a blown head gasket repair ? Here are some tell-tale symptoms to watch out for:
- White smoke from the exhaust
- Milky residue under the oil cap (oil mixing with coolant)
- Overheating engine, even after topping up coolant
- Loss of engine power
- Bubbling in the radiator or coolant overflow tank
If you’re experiencing any of these signs, it’s essential to book an inspection promptly to avoid further engine damage.
The Head Gasket Repair Process

- Initial Inspection & Pressure Testing
- Disassembly of Cylinder Head

In severe cases, we may recommend an engine rebuild or a remanufactured engine — both services we specialise in.
