🔍 Key Concepts

• How lube oil reaches the combustion space in a diesel or gasoline engine • The function of piston rings, valve guides, and valve seals in controlling oil • Difference between oil control problems in the cylinder wall vs. in the cylinder head/valve train

💭 Think About

• Think about which parts directly help scrape excess oil off the cylinder walls and prevent it from entering the combustion chamber. • Ask yourself: if this single part (and its matching components) is worn or broken, could oil get past it in more than one location in the engine? • Consider whether the question is asking for one specific cause or whether it allows for multiple different paths that all lead to high oil consumption.

✅ Before You Answer

• Make sure you understand the primary job of piston rings (especially the oil control ring). • Review what valve guides and valve seals each do to keep oil from being drawn into the combustion chamber through the intake or exhaust ports. • Check whether the wording "can result from" means only one correct cause or whether any of the listed conditions could logically cause the symptom.
