Sell a Car With a Blown Engine in Detroit for Cash

We buy cars with blown engines every week at Junk Car Scrappers Detroit. The story is almost always the same. The car made a noise, got towed to a shop, and came back with a $5,000 to $8,000 repair quote on a vehicle worth $3,000 running. This page covers the four types of engine failure, the real cost of replacement, when the math says fix it versus sell it, and what your damaged car is actually worth as-is.

What "blown engine" actually means

Blown engine is a catch-all term for any engine failure severe enough to require major internal work or full replacement. Here are the five most common types we see in Detroit.

Thrown rod or spun bearing

A connecting rod bearing fails from oil starvation, overheating, or sustained high RPM. The rod separates from the crankshaft and either knocks loudly or punches through the engine block. You hear a deep rhythmic knock that speeds up with RPM. This is engine damage that requires a full rebuild ($3,500 to $6,000) or replacement engine ($4,000 to $8,000 installed).

Cracked or warped block

Severe overheating cracks or warps the block itself. Coolant mixes with oil — look for milky residue on the dipstick or oil cap — and white smoke comes from the exhaust. A cracked block almost always means full engine replacement. Repair welding on aluminum blocks is rarely cost-effective. Replacement runs $4,500 to $9,000 installed.

Blown head gasket (severe)

The head gasket seals the engine block to the cylinder head. When it fails severely, coolant enters the cylinders or oil and coolant mix. A mild blown gasket repair runs $1,200 to $2,500. A severe failure — warped head, cracked head, scored cylinder walls — crosses into full replacement territory. Whether it is repairable or blown depends on what the mechanic finds when the head comes off.

Seized engine

The engine will not rotate at all. Causes include oil starvation, hydrolock from water ingestion, or years of sitting with rust on the cylinder walls. A seized engine is engine failure at its most final. The only fix is replacement. We buy seized cars regularly and a seized engine does not disqualify the vehicle from a cash offer.

Timing chain or belt failure

On interference engines — most modern vehicles — a broken timing belt or chain causes the valves to slam into the pistons while the engine is running. This destroys the cylinder head and often the pistons. A full top-end rebuild or engine replacement is required. This failure is almost always caused by overdue maintenance and is the most preventable type of engine damage on this list.

What engine replacement actually costs in Detroit

Used engine from a salvage yard

A used engine costs $800 to $2,500 depending on the vehicle and donor mileage. Add $1,500 to $3,000 in labor at Detroit shop rates ($75 to $160 per hour), plus $200 to $500 in ancillary parts (gaskets, fluids, sensors, mounts). Total installed: $2,500 to $6,000. Warranty is typically 90 days parts-only.

Remanufactured engine

A remanufactured engine rebuilt to factory spec costs $2,500 to $5,500. Installed total: $4,000 to $8,500. Warranty runs 12 to 36 months. This is the better option if you want the car to last another five-plus years and the math actually supports the repair.

New crate engine

A new crate engine costs $5,000 to $12,000 or more. Installed total can reach $15,000. Almost never makes financial sense on a vehicle worth less than $15,000 fixed. If you are pricing a crate engine for your car, selling it is almost certainly the right move.

The repair vs. sell math for Detroit cars

The rule: if the repair cost exceeds 50 percent of what the car is worth running, selling is usually the better decision. Below are four real examples using current Metro Detroit market values.

Vehicle	Running value	Repair cost	Ratio	Decision	Our offer range
2009 Toyota Camry, 175K miles	$3,800	$4,200	110%	Sell	$400 to $700
2014 Honda Accord, 130K miles	$7,200	$5,500	76%	Borderline	$700 to $1,100
2017 Ford F-150, 95K miles	$18,500	$7,500	41%	Repair	$1,200 to $2,000 if sold
2006 Chevy Impala, 220K miles	$1,800	$3,500	194%	Sell	$300 to $500

Repair makes sense on newer vehicles (2015 and up) with under 120,000 miles where the post-repair value comfortably covers the repair cost. For older or higher-mileage cars, selling is almost always the right call once the ratio crosses 75 percent — especially when you factor in what else is likely to fail in the next two to three years.

What your car with engine damage is worth in Detroit

Where the value comes from

A non-running car with a blown engine still has real value in several components. The transmission — if it was working when the engine failed — is worth $300 to $1,500 to a salvage buyer depending on the vehicle. The catalytic converter adds $50 to $300. Body panels, wheels, doors, and interior trim contribute another $200 to $600. The scrap metal value of the whole vehicle runs $150 to $400 based on curb weight. We look at all of it when we price a damaged car, not just the metal.

Typical offer ranges for a car with a blown engine

Compact cars: $250 to $600. Midsize sedans: $300 to $800. Trucks and full-size SUVs: $600 to $1,500. These ranges assume the catalytic converter is intact, the transmission was functional when the engine failed, and you have the title. Trucks pay top of range because truck parts move fast in the Detroit market. For a full breakdown of how junk car value is calculated, see our junk car valuation guide.

What to do right now

Step 1: Do not pay for a second diagnostic

If a reputable shop has already confirmed the engine failure, you have what you need. A second opinion costs $150 to $200 and almost always confirms the first. Keep the original diagnostic paperwork — we may ask about specifics when we quote you.

Step 2: Get a cash offer from us

Call (313) 889-7717 or use our instant offer form. We ask for year, make, model, mileage, what failed, whether the transmission still worked, title status, and your ZIP. Photos of the odometer and engine bay help. We quote in two minutes.

Step 3: Compare the numbers honestly

Stack the repair quote against our cash offer plus what you save in insurance, registration, and storage over the next year. For most vehicles that land on this page, the math comes out clearly in favor of selling. When it does not, we will tell you that.

Step 4: Schedule free pickup

We offer same-day or next-day flatbed pickup across Metro Detroit. The car does not need to run or roll. We handle the load-out and pay cash before the vehicle leaves your driveway.

Frequently asked questions

Is it ever worth fixing a blown engine?

Yes, on newer vehicles with low mileage where the post-repair value clearly exceeds the repair cost. In practice, that means 2015 or newer, under 120,000 miles, and a car worth more than $10,000 fixed. For older or high-mileage vehicles, the repair almost never pays off once you factor in what else is likely to fail in the next few years.

Should I try the engine swap myself?

Only if you have done it before, have a lift or engine hoist, and have several full weekends available. A DIY swap saves $1,500 to $3,000 in labor but introduces real risk: incorrect torque specs, missed sensor connections, and timing errors. For most sellers, the math does not work compared to selling the car and putting the cash toward a replacement vehicle.

What if the engine is degraded but not fully blown?

A car with a failing engine that still runs — smoking, knocking, burning oil but not yet seized — is worth more than a fully blown car, sometimes significantly more. Call us with the actual condition. An honest description of the engine problems produces a better offer than overstating it and getting reduced at pickup.

Does the catalytic converter affect the offer?

Yes, significantly. An intact converter adds $50 to $300 to the offer depending on the vehicle. Catalytic converter theft is common in Detroit — if yours was stolen, the offer drops by roughly that amount but we still buy the car. Converters from trucks and larger SUVs are worth more than those from compact cars.

Can I sell just the body and keep the engine?

Technically yes, but the math rarely works in your favor. Selling a blown engine as a core to a rebuilder typically yields $50 to $200 and requires you to remove it yourself. The labor cost of removal usually exceeds that gain. Selling the whole vehicle to us is faster, simpler, and almost always nets you more.

What if my car has a salvage title and a blown engine?

We buy salvage title vehicles with engine damage regularly. The title condition affects the offer somewhat because the resale market is narrower, but it does not disqualify the car. Call us with the full picture — year, make, model, condition, and title status — and we will give you a real number.
