Head Gasket Replacement Cost: Fix It or Junk It?
A blown head gasket is one of the most expensive common repairs because almost all of the cost is labor — typically $1,000 to $3,000 at a shop. On an older or high-mileage car, that often exceeds what the car is worth, which is why many owners sell it for cash instead.
Head gasket repair options (2026)
Cost ranges by approach. Labor dominates, so DIY saves the most.
| Option | Typical cost | Notes |
|---|---|---|
| Chemical sealer (temporary) | $30 – $100 | Short-term only; not a real fix |
| DIY repair (parts) | $100 – $400 | Major job; needs tools and time |
| Shop repair | $1,000 – $3,000 | Mostly labor; more if the head warped |
| Sell the car as-is | Instant cash | Common when repair exceeds value |
Estimates only — engine layout and how far the damage spread change the cost a lot.
Signs of a blown head gasket
Watch for white smoke from the exhaust, a milky "milkshake" residue on the oil cap or dipstick, overheating, coolant disappearing with no visible leak, and bubbles in the radiator. Driving on a blown head gasket can quickly warp the head and turn a $1,500 job into an engine replacement.
Repair or junk it?
If the repair is more than about half the car's value, selling it for cash usually beats fixing it — especially since head gasket jobs can uncover more damage once the engine is opened. Get a cash offer before authorizing the repair so you can compare.
