The correct flow sequence of lubrication oil is

Solution (By Examveda Team)

Oil Strainer: This is the first step. It's like a big sieve that catches large pieces of dirt and debris in the oil pan.
Oil Pump: This is the heart of the lubrication system. It sucks the oil from the strainer and pushes it through the system. Think of it as the engine that drives the oil flow.
Relief Valve: This valve is a safety measure. If the oil pressure gets too high (e.g., when the engine is cold or the oil filter is blocked), the relief valve opens to release some of the oil back into the oil pan. This prevents damage to the engine. It protects from overpressure.
Oil Filter: This is where the oil gets cleaned. The filter removes smaller particles of dirt and debris that the strainer missed. Clean oil is crucial for engine health.
Cylinder Block & Cylinder Head: The clean oil then flows to the engine's critical parts: the cylinder block (where the pistons move) and the cylinder head (where the valves are). It lubricates these moving parts to reduce friction and wear.
Oil Pan: Finally, after lubricating the engine, the oil flows back down to the oil pan, where it's ready to be pumped through the system again. This is where the oil collects.
