According to industry estimates, the cost of replacing an engine can be as high as $4,500 for a standard engine, while a high-performance engine can cost upwards of $7,000.
Causes and Symptoms
Internal engine failure can be a costly and frustrating experience.
A faulty timing chain or belt can cause engine failure, resulting in repair costs ranging from $500 to $2,000.
Poor maintenance, such as infrequent oil changes, can lead to premature engine wear and failure, which can cost upwards of $3,000 to replace.
Engine failure can also be caused by a blown head gasket, which can cost between $1,000 to $3,000 to repair.
Common Reasons

A hole in the engine block is a major problem that requires a replacement engine, not a rebuild. This can be due to a cracked engine block, damaged cylinder head, or other structural damage.
If the cost of rebuilding the engine is the same as or more than replacing it, it's often more practical to replace the engine. This is especially true for older cars where rebuild kits may no longer be available.
A used engine can be a viable option for some older cars, but it's essential to ensure it's a reliable and well-maintained option.
Here are some common reasons for engine replacement:
- Hole in the engine block
- Cost of rebuilding is the same as or more than replacing
- Older cars without available rebuild kits
Initial Diagnosis
A thorough diagnosis by a qualified mechanic is crucial before deciding on an engine replacement. They will assess the condition of your current engine and determine if replacement is the best option.
A series of tests and inspections are usually involved in this diagnosis, including a compression test. This test measures the engine's ability to compress air, which can indicate problems with the engine's cylinders or valves.
