Which risk increases when cylinder head bolts loosen after engine assembly?

💡 Explanation

Increased piston ring blow-by results because loss of head bolt clamping force reduces cylinder sealing via decreased compression. Therefore, combustion gasses leak past the piston rings, rather than containing them forcefully; accelerated connecting rod fatigue is a consequence of piston imbalance.
