How to Clean Inside an Engine Block

143

If your car’s engine has accumulated dirt, sludge and grease over the years, you may need to clean the inside of the engine block. Without proper cleaning, this accumulation can damage cam shaft bearings, crank shaft bearings and lifters. It can also block the oil galleries, restricting oil access to the vital parts of your engine. Cleaning the inside of an engine block is a difficult job that must be performed with the engine out of the car and mounted on an engine stand. After cleaning and reinstalling the engine in your car, you will notice an improvement in your engine’s performance.

Step 1

Mount the engine to an engine stand and connect the power washer or garden hose to a hot water source.
