A cracked engine block is one of the worst mechanical issues a vehicle can have and it is certainly among the most expensive to deal with. A cracked block can lead to overheating, leaks, extreme loss of power, or even complete failure of the engine altogether, and that’s just the tip of the iceberg when it comes to damage done to a vehicle. If you have recently discovered that your car has a cracked engine block and are unsure what your next step is, don’t worry. Whether you want to repair, replace, or sell the vehicle for parts, this guide will walk you through every possible option.
Indicators of a Cracked Engine Block
After all the considerations, it is important to detect whether your vehicle has a cracked engine block. The following signs are proximate indicators:
- Overheating Engine – Due to a crack, an overheated engine can result because cooling will escape.
- Coolant and Oil Mixing – The presence of frothy golden oil signifies contamination.
- White or Blue Exhaust Smoke – Coolant burning emits white smoke, while oil will produce blue smoke.
- Missing Leaks But Low Coolant Level – Internal leaking coolant could contribute to disappearing coolant levels.
- Power Loss and Poor Performance – Struggling to physically accelerate a cracked engine can lead to loss of compression-based power.
- Cracked or Leaky – Look for oil and coolant leaks around the engine block.
Can You Patch Up a Cracked Engine Block?
While a cracked engine block is technically repairable, it comes at quite an expense. Consider the following options:
Option 1: Wield the Crack
Most effective on: Small, external cracks.
✔ Pros:
It can be less expensive than a complete replacement.
Works best on non-structural cracks.
❌ Cons:
Not always a long-term fix.
Requires specialized tools and a skilled mechanic.
Option 2: Use Engine Block Sealer
Most effective on: Useful for stopping the full repair from being done for some time.
✔ Pros:
Very simple to apply.
Applies fast to stop coolant leaks temporarily.
❌ Cons:
No permanent solution.
Letting a seal fail could lead to a disastrous outcome.
Option 3: Replace Engine Block
Most effective on: Vehicles that are still valuable and worth fixing.
✔ Pros:
Restores full engine performance.
Extends the life of the car.
❌ Cons:
Expensive, often costing £2,000 – £5,000+.
Labor intensive and time-consuming.
What to Consider When Selling or Scrapping a Car With a Cracked Engine Block
If the repair cost makes more sense than the worth of the vehicle, you might want to consider selling or scrapping your car. Let’s dive into the details:
Private Sales
Best for: Cars sold on the market that possess valuable parts (e.g., luxury brands or newer models)
✔ Pros:
Buying the car as a shell could be a good deal for mechanics or car enthusiasts.
If the buyer wishes to rebuild the engine, selling it for higher prices is possible.
❌ Cons:
Finding a buyer can be time-consuming.
The selling price will likely be much lower than expected since the engine is damaged.
Selling to Scrap Yards or Auto Breakers
Best for: Older cars with little resell value
✔ Pros:
An instant cash offer can be obtained and the items collected for free.
No investment is needed in repairs.
The value of the materials can be recovered in an eco-friendly manner.
❌ Cons:
The payout will only be given according to scrap metal pricing and the weight of the car.
Trading In At The Dealership
Best for: If you are planning to buy a new car
✔ Pros:
Some dealers will offer trade-in value even if the car has some damage.
Optionally, this can also be done effortlessly.
❌ Cons:
Trade-in value is normally less than if the car is sold privately, or scrapped for parts.

The expenses of fixing the vehicle are low about its value.
