What's wrong with it
Selling a car with a blown engine
If a written estimate for the engine is more than the car would be worth once it's fixed, selling it as it is usually makes more sense. We buy whole non-running and junk cars, a blown or seized engine included, and we pick them up free wherever they sit.

The short answer
- Rod bearings (AAA range)
- $500 to $1,500
- Pistons or a rebuild (AAA range)
- $2,000 to $5,000 or more
- Blown head gasket or cracked block
- Can exceed $1,000 (AAA)
- Repair prices, Aug. 2019 to Aug. 2026
- Up 56% (BLS index)
- Recall repairs
- Free unless the first sale was over 15 years before the notice
- Paperwork to sell
- Same title transfer as a running car
Before you decide, get a diagnosis and check for an open recall. A cheaper fault, or a repair someone else has to pay for, can change the answer.
What the symptoms usually point to
These are warning signs, not a diagnosis. Most have more than one cause, so price the car on what a shop finds, not on a guess.
| What you notice | What it can point to | What it means for selling |
|---|---|---|
| Knocking or pinging from the engine | AAA lists fuel with too low an octane rating, low engine oil, or loose parts such as connecting rods, pistons or bearings | The cause sets the cost. AAA's ranges start at $500 to $1,500 for rod bearings; pistons or a rebuild run $2,000 to $5,000 or more |
| Overheating, steam, or coolant on the ground | AAA names leaks, a failed thermostat or water pump, or a clogged radiator, and says a blown head gasket or cracked block can exceed $1,000 | AAA says to pull over and turn the engine off. Don't drive it to a buyer |
| You keep topping up the coolant | AAA says a leak in the cooling system or in the engine may be the problem | Ask the shop where the coolant is going before you price the car |
| Milky or thick oil on the dipstick | AAA says this may mean a mechanical problem with the engine | Have a technician look, and include it in your description of the car |
| Blue, white or black smoke from the tailpipe | AAA Club Alliance says these colors often point to engine or emissions problems | Note the color. It helps the shop, and anyone pricing the car |
| Won't turn over, even with a charged battery | AAA says a single click or nothing at all can point to the starter motor. A seized engine is locked and won't turn either | AAA puts a starter at $300 to $800, far less than an engine, so rule it out first |
Fix it or sell it
Get the estimate in writing. Then compare it with what the same car sells for in working order where you live.
| Your situation | Usually the better move |
|---|---|
| No diagnosis yet | Pay for one. Don't price the car as dead on a guess |
| A recall or warranty covers the fault | Get the covered repair, then decide |
| The estimate is well under what the car is worth fixed, and you'll keep driving it | Fix it |
| The estimate is close to or above that value | Sell it without fixing it |
| Other big repairs are due soon too | Add them to the estimate before you compare |
| You need the car gone and can't wait on a shop | Sell it as it is |
Repairs cost more than they used to
The Bureau of Labor Statistics tracks what people pay for vehicle maintenance and repair. Its index stood at 297.9 in August 2019 and 465.1 in August 2026, a rise of 56% (seasonally adjusted, 1982 to 1984 = 100). Over the last 12 months of that series it rose 5.2%.
An index follows prices in general, not the price of your job. The written estimate is still the number to decide on.
Check for a recall and a warranty first
Enter the 17-character VIN in NHTSA's recall lookup. It shows unrepaired recalls on that exact car for the makers the tool covers. NHTSA notes that some recently announced recalls may not show up yet.
Federal law lets a maker charge for a recall remedy only if more than 15 calendar years passed from the first purchase to the notice (49 U.S.C. 30120(g)). That clock runs from the first owner's purchase to the announcement, not to today, so an older car can still qualify.
If the car is still under the maker's warranty, or you bought a service contract, read it before you pay for an engine. The FTC says a dealer can't deny warranty coverage just because someone else did your routine maintenance. But if the warranty says the work will be done for free, the dealer or maker can choose where it's done. Keep your maintenance records, because the warranty company may ask for them.
Don't pull the engine before you sell
Selling the engine on its own and scrapping the rest sounds smart. But offers are priced on a complete car, and an empty engine bay is the first thing a driver sees. If you're weighing a part-out, read whether to part it out or sell it whole first. If parts are already gone, see selling a car that's missing parts.
What to tell us
- Year, make, model and mileage.
- What happened, and what the shop said if you have a diagnosis.
- Whether it rolls, whether the wheels are on, and where it's parked.
- Whether the title and keys are in hand.
The offer is built on what you tell us, and a problem left out can change it when the car is collected, so describe the engine trouble as it is. You can turn down any offer. Start online, or call (877) 421-6008.
If the trouble is the transmission rather than the engine, the bad-transmission page has the details. If it simply won't start, see selling a car that doesn't run. What a junk car is worth explains what moves the number.
Questions people ask
- Will you buy a car with a seized engine?
- Yes. A seized engine is no exception: we buy whole non-running and junk cars, picked up as they sit, and the tow costs you nothing.
- Do I have to get it running before I sell it?
- No. A dead engine doesn't change the paperwork. You sign the title over as usual, and the car rides away on a truck.
- Is it worth putting in a new engine before selling?
- Only if the car will be worth clearly more than the repair once it's done, or you plan to keep driving it. Get the estimate in writing and compare it with what the same car sells for in working order. AAA prices new pistons or an engine rebuild from $2,000 to $5,000 or more.
- Could a recall pay for the engine?
- Only if an open recall covers the fault. Check the VIN on NHTSA's recall lookup. Federal law makes the fix free unless the first buyer bought the car over 15 calendar years before the recall notice went out.
- Should I pull the engine and sell it separately?
- Usually not. An offer for the car assumes it's complete, so a missing engine lowers it, and you'd still need tools, time and a buyer for the engine. If parts are already gone, tell us exactly what's missing.
