🔍 Key Concepts

• How combustion gases can leak past the piston rings into the crankcase • What component wear would increase the amount of blow-by into the crankcase • Normal purpose and operation of crankcase relief/mannhole covers vs. what causes them to lift

💭 Think About

• Which of these conditions would allow more combustion gases to pass into the crankcase space during normal operation? • Do worn bearings significantly change gas flow into the crankcase, or mainly affect clearances and noise/vibration? • Is high cylinder temperature itself the cause of increased crankcase pressure, or is there another mechanical condition that would more directly increase gas leakage into the crankcase?

✅ Before You Answer

• Match the choice that directly increases blow-by from the combustion space into the crankcase • Eliminate options that mainly cause mechanical wear or noise but not a large change in crankcase gas flow • Consider if safety covers are a result of high pressure, rather than the root cause of it
