Which risk increases when elevated temperatures cause piston ring sticking in a diesel engine?

💡 Explanation

When high temperatures cause piston ring sticking, there is reduced sealing because carbon deposits prevent the rings from fully expanding against the cylinder wall, leading to increased blow-by and reduced compression. Therefore, increased blow-by results, rather than fuel dillution, turbocharger issues, or crankshaft failure which stem from different mechanisms of thermal or mechanical stress.
