By monitoring the color of the smoke, a technician can narrow down the source. Oil circulates on the backside of these pistons to provide cooling, yet the design inherently allows for a minimal amount of oil to pass by the rings into the combustion chamber.
Understanding How Oil Reaches the Combustion Chamber and Burns
When these rings lose their tension or become damaged, they fail to scrape excess oil from the cylinder walls effectively, allowing oil to pool and subsequently burn off. A significant drop in pressure indicates ring or cylinder wall wear.
In a healthy engine, this oil is burned efficiently, producing negligible amounts of blue smoke. A significant drop in pressure indicates ring or cylinder wall wear.
How Oil Burning Happens: Piston Ring Wear and Compression Loss
A compression test measures the sealing ability of the pistons and rings by assessing cylinder pressure. These quantitative measurements transform a suspicion of burning oil into a confirmed diagnosis.
