Failure to remove the carbon ridge from the top of the cylinder, when replacing the piston rings, will result in __________.

🔍 Key Concepts

• Function of piston rings during operation and how they move in the cylinder bore • What a carbon ridge is and where it forms at the top of the cylinder • What part of the piston makes contact with the top of the cylinder bore when new rings are installed and the engine is first started

💭 Think About

• When you install new piston rings, how does their position in the bore change compared to worn rings? What area of the cylinder will they now reach that the old rings did not? • If there is a hard carbon step at the top of the cylinder, which part of the piston assembly is most likely to strike that step first when the engine runs? • Think about which component runs closest to the very top of the ring travel: the ring faces, the ring lands, the liner wall, or the piston skirt?

✅ Before You Answer

• Identify which components actually travel up into the ridge area at top dead center (TDC) with new rings installed • Confirm what a carbon ridge physically looks and feels like (a hard step at the end of ring travel) and which part would hit that step first • Eliminate any options that describe damage to parts that do not normally reach the top ridge area or are shielded from direct contact with it
