What the symptoms mean
  • Overheating: The head gasket has failed, allowing combustion gases to enter the cooling system.
  • White smoke: Coolant is being drawn into the combustion chamber and burned.
  • Mayonnaise: Coolant mixing with oil - a sure sign of head gasket failure.
  • Coolant loss: Coolant is being burned in the combustion chamber.
  • Misfire: Coolant in the cylinder disrupts combustion.
⚠️ The ticking clock

A blown head gasket is a ticking time bomb. Continuing to drive will: 1. Warp the cylinder head - requiring skimming or replacement. 2. Crack the cylinder head - requiring replacement. 3. Damage the engine block - requiring replacement. 4. Destroy the engine - complete engine replacement required.

Cylinder head skimming

What it is and why it's essential

What is head skimming- The cylinder head is machined on a surface grinder to remove any warping. This ensures a perfectly flat surface for the new head gasket to seal against.

Aspect Detail
Typical cost£80-£150
When it's neededAlmost always - overheating warps the head
How much is removed0.1-0.5mm (depending on warpage)
When it's not possibleIf warpage exceeds 0.5mm or if the head is cracked
Why skimming is essential
  • The new head gasket won't seal properly if the head is warped
  • The repair will fail - often within weeks or months
  • You'll pay for the job twice
Skimming limit

Most manufacturers specify a maximum skimming limit (typically 0.2-0.5mm). If the head is warped beyond this, it must be replaced.

Repair vs replace

When repair is viable vs when replacement is better

Scenario Action Typical Cost Viability
Blown gasket, head flatHead gasket replacement£550-£1,200Best case - repair is viable
Blown gasket, head warpedHead gasket + skimming£630-£1,350Viable - if not warped beyond limit
Blown gasket, head crackedHead replacement£1,500-£3,500+May be viable - depends on vehicle value
Block damagedEngine replacement£2,000-£5,000+Usually the best option - expensive
Engine overheated badlyEngine replacement£2,000-£5,000+Often more economical than repair
Repair vs replacement threshold
  • Under £2,000: Consider scrapping
  • £2,000-£4,000: Head gasket repair viable
  • £4,000-£8,000: Repair is logical
  • £8,000-£15,000: Definitely worthwhile
  • £15,000+: Repair or replace as needed
The rule of thumb

If the repair cost exceeds 50-60% of the vehicle's market value, consider scrapping or selling for parts. However, rare, collectable, or sentimental vehicles may justify spending above this threshold.

Consequences of delay

What happens if you keep driving

Stage Issue Cost

What's the most common cause-

What's the Most Common Cause of Head Gasket Failure-

The top causes
  • Overheating - the most common cause (60%+ of failures)
  • Poor maintenance - infrequent coolant changes, low coolant
  • Age and wear - gaskets degrade over time
  • Design issues - some engines are more prone to failure
  • Turbo issues - turbo failure can cause overheating
  • Head bolt failure - stretched or broken head bolts
Why overheating causes head gasket failure
  • The cylinder head expands more than the block
  • The head gasket is compressed and stressed
  • The gasket fails - allowing coolant, oil, and combustion gases to mix
  • The head warps - making the problem worse

Before you agree

10 questions to ask before repairing your head gasket

Asking the right questions can save you thousands and prevent disputes. Here's a checklist specific to head gasket repair.

1. "What's included in the repair price-"

Get a full written breakdown. Ask specifically about: head gasket set, skimming, labour, coolant, oil and filter, and testing.

2. "Will the cylinder head be skimmed-"

Skimming is essential if the head has warped. Ask if it's included and what the cost is. If the head isn't skimmed, the repair may fail.

3. "What's the condition of the cylinder head-"

Ask if the head is cracked or warped beyond the skimming limit. If it is, you may need a replacement head.

4. "What warranty do you offer on the repair-"

Typical warranty for head gasket work is 12-24 months on parts and labour. Get it in writing.

5. "What additional work is recommended while the head is off-"

Ask about: timing belt/chain, water pump, thermostat, valves, and valve guides. Doing these now saves labour later.

6. "Will you pressure test the head for cracks-"

A pressure test (dye penetrant or magnetic particle) checks for cracks. Ask if this is included.

7. "What's the total cost including all parts and labour-"

Get a full written breakdown. Ask about any potential additional costs.

8. "What's the timeline from booking to completion-"

Get a realistic estimate. 4-cylinder typically 2-4 days; V6/V8 3-5 days.

9. "Do you have experience with my engine type-"

Ask about the specialist's experience with your specific engine. Some engines have known head gasket issues.

10. "Can you provide a written quote-"

Get everything in writing before agreeing. The scope of work, cost, timeline, and warranty terms should all be documented.

Can I drive with a blown head gasket- +
No - you should stop driving immediately. Continuing to drive will warp the cylinder head, crack the block, and destroy the engine. The cost of repair will escalate from £550-£1,200 to £2,000-£5,000+ for engine replacement.
What's included in head gasket repair- +
Head gasket set, cylinder head skimming (if required), labour (8-15 hours), coolant refill, oil and filter change, and testing. Additional work (timing belt, water pump, etc.) is typically extra.
How long does head gasket repair take- +
Typical repair time is 2-5 days. 4-cylinder engines take 2-4 days. V6/V8 engines take 3-5 days. The timeline depends on vehicle complexity, parts availability, and the specialist's workload.
Is it worth repairing a head gasket on an old car- +
If the car is worth £2,000+ and otherwise in good condition, it's usually worth repairing. If the car is worth under £2,000, consider whether repair is economically viable. However, if the engine is destroyed, you'll need a new car or engine replacement (£2,000-£5,000+).
What's the most common cause of head gasket failure- +
Overheating is the most common cause (60%+ of failures). Other causes include poor maintenance (infrequent coolant changes), age and wear, design issues, turbo failure, and head bolt failure.
Should I replace the head gasket or the engine- +
If the head gasket has blown but the head and block are intact, repair is viable. If the head is cracked, warped beyond skimming, or the block is damaged, engine replacement may be more economical. A specialist will advise.
Can I repair a head gasket myself- +
Head gasket replacement is not a DIY job for most owners. It requires specialist tools, knowledge of engine timing, and careful handling. Incorrect installation will cause the repair to fail. Use a specialist.
What's the labour time for head gasket repair- +
