The cost of replacing a blown head gasket can vary widely depending on factors like the make and model of the vehicle, labor rates in your area, and whether any additional damage was caused to other engine components. On average:
- Labor costs: Replacing a head gasket is labor-intensive and can take between 8 to 20 hours, depending on the complexity of the engine. Labor rates can range from $75 to $150 per hour, leading to labor costs of around $600 to $3,000.
- Parts costs: The head gasket itself typically costs between $50 and $500, depending on the vehicle. Additional parts, such as bolts, seals, and possibly a new cylinder head or machine work (e.g., resurfacing), can add $100 to $1,000 or more.
- Total cost: For most vehicles, replacing a blown head gasket can cost between $1,000 to $3,500. For high-performance or luxury cars, the cost could be higher, potentially reaching $4,000 to $5,000 or more.
If the engine sustained significant damage (e.g., warped or cracked cylinder heads), the total cost could increase further. It’s always a good idea to get a detailed estimate from a repair shop before proceeding.
