Which consequence results when cylinder head gasket erosion increases blow-by?

💡 Explanation

Increased blow-by past the piston rings reduces engine volumetric efficiency because pressure escapes the combustion chamber, causing less air-fuel mixture drawn in on the intake stroke; therefore, power decreases rather than increasing combustion or changing injection pressures. The mechanism is pressure loss.
