Therefore, this can be the weakest link in a block besides its internals if it does not have enough structural support and thickness. Detonation is like a giant hammer pounding on the top of the piston and this impact goes straight down the connecting rod and into the rod bearing which pushes out the very small film of oil keeping the rod bearing and rod journal on the crankshaft from making metal to metal contact with each other. It connects the crank to the piston, which is forced to move in and out of the cylinders by internal combustion (explosions). The cylinder walls are exposed to explosions with high heat and impact, and expand and contract when the engine is on and off. The first was EJ22E engine.
