When to Replace or Rebuild A Car Engine

A car engine can have as many as 1,400 parts. Sooner or later, one of these parts, such as the head gasket or timing belt, is going to wear out. Once the engine begins to croak, the owner will need to decide whether to replace or rebuild the car engine.

What Causes Engine Failure?

Some simple car maintenance by an auto mechanic can generally prevent engine failure. But when something significant breaks, such as an oil pump or cooling system, other internal components might begin to fail. This could cause serious damage to an already aging engine. Other common causes for major engine failure include a broken thermostat, low oil levels, a clogged heater core, and poor engine oil lubricity.

The extent and cause of engine failure determines whether you should replace or rebuild the engine.

Rebuilding an Engine Explained

Many people are unfamiliar with an engine rebuild. In a rebuild, the engine is disassembled. A technician inspects, cleans, and replaces worn individual parts with new or refurbished pieces. The timing belt, seals, gasket, valve springs, and O rings are the parts mechanics replace most often. In some instances, the mechanic may have to bore the engine block to realign it with the crankshaft main bores.

Engine rebuilding is beneficial because the car retains the original engine, ensuring compatibility with the car and its engine control unit. Even a new engine from the same car model and year may not be 100% compatible.

If multiple parts sustain damage, then the total cost of labor and individual parts replacement might exceed the cost of a new engine. In this case, you’re better off replacing the engine unit.
