Can You Change Main Bearings with Engine in Car?

Introduction

Main bearings are essential components in an engine. They support the crankshaft and allow it to rotate smoothly. Over time, main bearings can wear out and need to be replaced. This is a complex and time-consuming job, and it is typically not recommended to attempt it unless you have experience working on engines.

Can You Change Main Bearings with the Engine in the Car?

In most cases, it is not possible to change main bearings with the engine still in the car. This is because the main bearings are located deep within the engine, and they are surrounded by other components that must be removed in order to access them. Removing these components would require a lot of time and effort, and it would be very difficult to do without damaging the engine.

However, there are some exceptions to this rule. In some cases, it may be possible to change main bearings with the engine still in the car if the engine is small and there is enough room to work. This is a very rare situation, and it is not something that should be attempted unless you are confident in your abilities.
