Piston rings are crucial components in an engine that:
Serve with two main purposes
What is one main purpose of piston rings?
Seal the combustion chamber to prevent leaks
What is the second main purpose of a Piston Ring?
Allowing pistons to move freely within the cylinder
When piston rings wear out:
They can no longer effectively seal the combustion chamber, leading to oil leaks into the chamber
As a result:
The engine burns the leaked oil, producing the blue smoke and requiring excessive amounts of oil to function properly
