🔍 Key Concepts

• compression vs lubrication functions of piston rings • path that combustion gases take if they escape the combustion chamber • difference between valve train leaks and piston/cylinder leaks

💭 Think About

• Think about what blow-by actually is: where are the gases coming from, and where are they going? • Which engine parts are supposed to seal the combustion chamber during the power stroke? • Which choice is mainly for controlling oil on the cylinder walls rather than sealing high-pressure combustion gases?

✅ Before You Answer

• Be clear on which components form the primary gas seal between piston and cylinder wall. • Distinguish parts that seal at the top of the cylinder (valves/valve seats/valve guides) from parts that seal around the piston. • Verify which ring type’s main job is controlling oil film versus holding compression.
