Additionally, ensuring the breather system is functioning optimally prevents the buildup of pressure that accelerates ring and cylinder wear. Regular oil changes remain the single best preventative measure against the conditions that lead to blow-by.
Perform Visual Checks to Spot Blow-By Symptoms Early
During the power stroke, the ignited air-fuel mixture generates immense pressure that forces itself past the piston rings and into the crankcase. This is a major engine rebuild that requires mechanical skill or professional assistance.
Understanding the Mechanics of Blow-by To fix blow-by, one must first understand its origin. If the PCV valve is stuck open or the hoses are clogged, it can cause excessive pressure or vacuum conditions that force the rings past their limits.
Performing Visual Checks to Spot Blow-By Symptoms
The Solution: Replacing Worn Components The most common fix for significant blow-by is replacing the piston rings and, if necessary, the cylinder liners. The symptoms of blow-by include blue-tinted exhaust smoke, a sudden drop in oil level, and a milky appearance of the oil filler cap or dipstick.
