Engine Blow By: Causes, Effects, and Prevention

In the world of lubricants and engines, addressing issues like engine blow by is crucial for optimal performance and longevity. Engine blow by, a common concern in the automotive industry, can have detrimental effects on efficiency. Today we'll delve into the causes, effects, and preventive measures related to engine blow by.

Causes of Engine Blow By

Understanding the root causes of engine blow by is essential. One primary factor is worn piston rings, allowing combustion gases to escape into the crankcase. Additionally, faulty valve seals and excessive cylinder wear contribute to increased blow by. Identifying these issues early on is key to preventing further damage.

The fundamental cause of stuck piston rings and glazed cylinder bores in many cases is the accumulation of carbon deposits and sludge in the engine. Over time, as the engine operates, various byproducts of combustion, as well as contaminants from the oil and fuel, can build up and form deposits. This can happen for several reasons:

Incomplete Combustion

If the air-fuel mixture in the combustion chamber does not burn completely, carbon deposits can form on the piston rings and cylinder walls.

Oil Contamination

Contaminants in the engine oil, such as dirt, metal particles, and other impurities, can contribute to the formation of sludge. This sludge can interfere with the proper movement of piston rings.

Poor-Quality Fuel

Low-quality or contaminated fuel may contain impurities that contribute to carbon buildup in the combustion chamber.

Engine Oil Breakdown: Over time, engine oil breaks down and loses its lubricating properties. This can lead to increased friction between moving parts, promoting the formation of deposits.

Short Trips and Cold Starts

Engines may not reach optimal operating temperatures during short trips or in frequent cold starts. This can lead to the incomplete combustion of fuel and contribute to the buildup of deposits.

The carbon and sludge deposits can cause the piston rings to become stuck in their grooves, hindering their ability to seal the combustion chamber properly. Additionally, these deposits can create a glazed surface on the cylinder bores, reducing their ability to retain oil and affecting overall engine performance.

Regular maintenance practices, such as using high-quality fuel and oil, following recommended oil change intervals, and performing periodic engine cleanings, can help prevent the buildup of carbon and sludge, ultimately extending the life of the engine and reducing the risk of piston ring and cylinder bore issues.

Effects of Engine Blow By

The effects of engine blow by can be detrimental to overall performance. Reduced power, increased oil consumption, and elevated emissions are common consequences. Ignoring these signs may lead to more severe damage, affecting not only the engine but also the environment and your budget.

Preventing Engine Blow By

Prevention is the best strategy when it comes to engine blow by. Regular maintenance, including timely oil changes and using high-quality synthetic lubricants like AMSOIL, can significantly reduce the risk. Ensuring proper ventilation of the crankcase and addressing issues promptly contribute to preventing blow by and maintaining optimal engine performance.
