Difference Between Minor and Major Engine Repairs
Minor Engine Repairs
Sometimes, the “engine serviced” term means small issues that were successfully fixed early on before they became big problems. Such repairs include fixing oil leaks, replacing ignition coils, hose replacements, or sensor replacements (MAP sensor, oxygen sensor, etc). These are pretty normal repairs, especially on cars with higher mileage.
More Serious Engine Work
This type of engine work is less common and is done in very few cases. This may involve head gasket repair, valve repairs, timing belt or timing chain service, or engine misfire repair or diagnosis. Even for her, the context really matters. After all, a well-documented repair is better than a vehicle with zero vehicle service history.
