🔍 Key Concepts

• Chrome-plated piston rings and how they show signs of gas leakage • Difference between normal wear patterns and evidence of blow-by • How combustion gases or oil flow would mark the ring face near liner ports

💭 Think About

• What would cause vertical streaks specifically, as opposed to circumferential scratches or chips? • If combustion gases are passing the ring, how might they discolor or mark the ring surface? • Which option describes a condition, not a single failure event (like a break), that would leave a repeated pattern on multiple rings?

✅ Before You Answer

• Look at the direction of the streaks and relate it to gas flow in the cylinder (up/down vs around). • Consider whether a broken ring or a leaky injector would consistently create neat vertical brown streaks on the ring face. • Ask: under truly normal conditions, would you expect visible brown staining/streaking on the ring face, or a clean, even appearance?
