Sell a car with a failed engine
You can sell a car with a failed engine exactly as it is - no repair, no MOT, and no need to get it running again. Whether the failure is from a blown head gasket, a snapped timing belt, overheating, or a seized engine, Sell The Car will give you a free valuation and collect the car at no cost, anywhere in the UK.
What Causes Engine Failure?
Engine failure usually comes from one of a small number of root causes:
- Missed oil changes — oil breaks down over time and stops lubricating properly if it isn't replaced on schedule
- Unaddressed oil leaks — left long enough, a leak starves the engine's moving parts of lubrication
- Ignoring the engine warning light — by the time the light comes on, damage may already be underway
- Cooling system faults — a failing cooling system causes overheating, which can warp the cylinder head or damage internal components within minutes
- Water ingress (hydrolock) — water entering the engine, for example from deep flooding, doesn't compress like air and can bend or snap internal components almost instantly
Identifying the cause doesn't change whether you can sell the car — it's only relevant if you're deciding whether a repair is realistic.
Is It Worth Repairing a Failed Engine?
This is purely a value comparison. A full engine rebuild typically costs £3,000–£6,000+ depending on the extent of the damage, and a full engine replacement can exceed £5,000. If that figure is close to or above what the car is worth in good running condition, repair doesn't make financial sense, you'd be spending more than the car would be worth even with a perfect engine.
As a rough guide: if the repair quote is under roughly 30% of the car's value, fixing it usually pays off. Above 50%, most owners are better off selling as-is and putting that money toward a different car rather than a repair on a depreciating one.
Can I Sell a Car With a Completely Seized Engine?
Yes. A seized engine, one that won't turn over at all, doesn't prevent a sale. It does mean the car needs to be recovered rather than driven, which is exactly what a specialist non-runner buyer is set up to do. You don't need to attempt to start it, diagnose the exact failure, or get any repair quotes before selling.

FAQs
Do I need to know what caused the engine failure to sell the car?
No. A general description — for example, "won't start" or "overheated and now won't run" — is enough for an initial offer.
Is engine failure covered by car insurance?
No, in most cases. Mechanical wear and failure isn't an insured event under standard car insurance, unlike accident or fire damage. Some extended warranties may cover specific failures depending on the policy.
Can I sell a car with a seized engine without an MOT?
Yes. There's no legal requirement for a car to be driveable or have a valid MOT in order to sell it — only the V5C registration certificate is needed to transfer ownership.
Is it cheaper to scrap an engine-failed car instead of selling it?
Usually not. A specialist buyer values the whole car, including parts and components unaffected by the engine fault, which typically returns more than scrap value alone.
