Toyota 4Runner Pistons, Rings & Connecting Rods

Commonly known as a rotating assembly, pistons, connecting rods, and crankshaft belong to the principal components of any reciprocating engine. In fact, these parts can be considered the core components of the entire assembly, as they transform the pressure from hot gases into the rotational motion propelling the vehicle and powering all its accessories. In this scheme, piston rings play an important role. Each of the pistons has a set of rings sealing the combustion chamber within the cylinder walls, minimizing loss of gasses to the crankcase, and not letting the oil get into the combustion chamber. Piston rings are susceptible to wear and tear due to a constant friction between the rings and cylinder walls.

Experiencing enormous stresses and wear, piston rings are a common problem that the owners of aging vehicles of all forms and sizes encounter. And your Toyota 4Runner is no exception. The metal parts that Toyota puts under the hoods of their SUVs are known for their durability and high wear-resistant properties. However, their service life is still limited. And when this limit is reached, the replacements should be strong and capable.
