Oil pans are usually fashioned out of steel or aluminum. They vary in shape and size depending on engine oil
capacity, engine compartment clearance, and internal design. Internal designs vary depending on application.
Some pans require extensive baffling of the oil bath from the crankshaft, others not so much. All this affects
the shape and size of the oil pan.
Cylinder Head
The cylinder head sits high on top of the engine block. (There are two heads on
engines with two banks of cylinders.) The valves are situated inside the cylinder
head. Here’s how it all works.
All the parts of the engine must work in sync during the four-stroke cycle.
Perfect timing of the moving parts is essential for the engine to function. There
are two types of mechanical timing drives that control the timing of these parts: a
chain drive and a belt drive.
