Nissan Sentra Pistons, Rings & Connecting Rods

Engine pistons inside the cylinders function like moving plugs pushed by combustion gases. In order to provide the necessary sealing between the cylinder wall and piston, there are one or two piston rings; the third ring of a special shape is needed to remove excessive motor oil from cylinder walls. A connecting rod is used to connect the piston to the crankshaft. Together with engine bearings, all aforementioned parts belong to the engine rotating assembly. Some of the common problems in this part of an automobile include worn-out or clogged piston rings, burnt pistons, and abnormal wear of cylinder walls.

A piston can get damaged due to excessively high combustion temperatures. This situation may take place because of premature ignition caused by hot spots in the combustion chamber or lean air-fuel mixture. Piston scuffing is usually a result of overheating or insufficient clearance between the piston and cylinder. Cracked pistons or broken ring lands are a typical consequence of detonation damage. A number of Nissan Sentra owners complain about the piston slap, but in many cases, the issue does not need any interference and goes away as soon as the engine warms up.
