If your mechanic says the engine is blown, you are probably looking at more than a tune-up or sensor repair. A seized crankshaft, thrown rod, spun bearing, cracked block, hydrolock, or metal shavings in the oil usually means catastrophic internal damage.
For many St. Louis Metro donors, the next choice is whether to pay for an engine replacement, try to sell the car broken, or donate it. Rev Up Local can accept non-running vehicles with diagnosed blown engines, arrange free towing, and provide the tax paperwork after the vehicle is sold.
The failure and the repair-cost reality
A blown engine is not a small drivability problem. It usually means catastrophic internal damage: a seized crankshaft, a thrown connecting rod, spun bearings, a cracked block, hydrolock, or similar damage inside the engine. The symptoms often come on fast: loud knocking, sudden loss of power, metal shavings in the oil, or an engine that will not turn over at all.
When a mechanic gives this diagnosis, the realistic fix is normally a full engine replacement. That may mean a remanufactured engine or a used engine, plus roughly 10 to 20 hours of labor, fluids, gaskets, and related parts. Published engine replacement ranges often fall around $4,000 to $8,000, depending on the vehicle and the engine used. That range is why many St. Louis Metro owners stop and compare the quote against the car’s actual value before approving the work.
Local driving can add to engine wear over time. Stop-and-go traffic, long highway miles on I-64, I-70, I-44, or I-55, hot Missouri summers, cold starts in winter, and road salt exposure on older cars can all make an already tired vehicle less worth saving when the engine has failed internally.
Why donating beats repairing or selling private-party for this failure
The math is the hard part. If the repair range is $4,000 to $8,000, you are comparing that bill against a vehicle that currently does not run and will not run again without a replacement engine. An older car with a blown engine is usually not valued like the same car in running condition. It is typically viewed as a project, parts vehicle, rebuild candidate, or scrap vehicle.
That creates a value gap. At the low end, a $4,000 engine job may still be more than a high-mileage older car is worth to keep. At the high end, an $8,000 repair can easily exceed what many older vehicles would bring even after they are running again. The gap is the repair bill minus the reduced value of a non-running car with known internal engine damage. Rev Up Local will not tell you that donation creates a higher dollar outcome than repair or sale; it simply removes the tow problem and gives you a documented charitable donation path.
Private-party selling is possible, but this diagnosis makes it harder. You have to be very clear that the engine is blown, not just “needs work.” Buyers may want to inspect it, negotiate around the engine replacement cost, or ask you to arrange towing. Donation can be simpler when you already know you do not want to put thousands of dollars into a car with catastrophic internal engine damage.
How donation works for a non-runner and what happens to the car
Rev Up Local accepts vehicles with blown engines in the St. Louis Metro area, including non-runners. Towing is free. When you start the donation, describe the diagnosis honestly: seized crankshaft, thrown rod, spun bearing, cracked block, hydrolock, metal in the oil, or whatever your mechanic wrote on the quote. This does not disqualify the vehicle. It helps the towing and sale process go smoothly.
You will generally need a clear title in your name. If you are unsure about a Missouri title issue, ask before the pickup is scheduled. Remove personal items and license plates, and have the keys available if you have them, even if the engine will not turn over.
After pickup, a mechanically dead donated car is usually sold through the appropriate resale channel. It may go to an auction where rebuilders bid on it, be sold for usable parts, or be scrapped for metal value if that is the practical outcome. The proceeds benefit Heritage for the Blind, a 501(c)(3) nonprofit, EIN 58-2164446, supporting programs for people who are blind or visually impaired.
For taxes, Rev Up Local provides a receipt. If the vehicle sells for more than $500, your deduction is generally the gross sale price, reported on IRS Form 1098-C. If it sells for $500 or less, you may generally claim fair market value up to $500. No one should promise you a specific donation value before the vehicle is sold.
Repair cost vs. donating
Typical repair
$4,000–$8,000
A blown engine repair usually means replacing the entire engine with a remanufactured or used engine, plus about 10 to 20 hours of labor and related parts, which is why published ranges often run from $4,000 to $8,000.
What the car is worth
A car with a seized crankshaft, thrown rod, spun bearing, cracked block, hydrolock, or similar internal damage is typically valued as a non-running project, parts vehicle, rebuild candidate, or scrap vehicle, not as a normal running car. For many older vehicles, the repair range can exceed the vehicle's practical value.
Donate instead
Rev Up Local can accept the vehicle as-is, arrange free towing for non-runners, provide the appropriate tax receipt, and direct sale proceeds to Heritage for the Blind programs for people who are blind or visually impaired.
Common questions
Will Rev Up Local take my car if the engine is completely seized?
Yes. A seized engine does not automatically disqualify the vehicle. Be clear that the crankshaft is seized or that the engine will not turn over. Rev Up Local can arrange free towing for non-runners in the St. Louis Metro area, as long as pickup access and title requirements can be handled.
Should I replace the engine before donating?
Usually not if your goal is donation. Engine replacement commonly falls in the $4,000 to $8,000 range, and a blown-engine vehicle is already treated as non-running. Donating it as-is avoids putting more cash into a car that may still be worth less than the repair once the work is finished.
Do I need to hide or soften the blown engine diagnosis?
No. Describe it accurately. Say whether the mechanic found a thrown rod, spun bearing, metal shavings, hydrolock, cracked block, or a no-crank condition caused by internal damage. Honest disclosure does not prevent donation. It helps the program route the vehicle properly and helps avoid pickup or auction surprises.
What happens to a donated car with a thrown rod or cracked block?
It may be sold at auction to a rebuilder, sold for usable parts, or scrapped for metal value if repair is not practical. Even when the engine is dead, the sale proceeds still help fund Heritage for the Blind programs for people who are blind or visually impaired.
How much can I deduct for donating a blown-engine car?
The IRS rules depend on the sale price. If the vehicle sells for more than $500, your deduction is generally the gross sale price and you receive Form 1098-C. If it sells for $500 or less, you may generally claim fair market value up to $500.
More donation guides
A blown engine is one of the clearest moments to stop spending on an older car and choose a practical next step. If your repair quote is bigger than the car is worth to you, Rev Up Local can help you donate it as-is, with free towing for non-runners and a tax receipt after sale. Start with the donation form or call Rev Up Local with the diagnosis from your mechanic.
