Blow By Gases

Explanation:

Compression gases that do find their way past the rings and into the engine block’s lower area are called blow-by gases. You may hear someone say that an engine “has blow-by” or “has too much blow-by.” The term blow-by refers to whatever combustion gases “blow by” the compression rings. Too much blow-by means that the engine’s piston rings are worn or damaged in some way, allowing combustion gases to leak past the rings and into the engine block’s lower area
