At first glance, this part might seem easy — just a block with a few circles and cutouts.
But when you think with an engineering mindset, it becomes much more complex.

The key question is:

• Should this be made from a solid metal block, machined with CNC or laser cutting?
• Or should it be produced by mold making, which is often the preferred method for engine components to ensure higher strength and durability?

In practice, most engine parts are manufactured through mold making first, and then undergo CNC machining to achieve high precision.
