We just learned about the Oil Galleries.

Another part of a car engine is the Camshaft.

We learned a long time ago that a Cam is a disc with a bump on it that spins around and pushes down to open up valves for the engine.

The camshaft is the long metal pole that cams are attached to.
The shaft spins around, and the cams take turns pushing down with their bumps at different times.
