The oil gallery is a type of core plug.

• A. True
• B. False
• C. Sometimes
• D. Not related

Answer: (A)

The oil gallery serves as the network of internal oil passages in the engine block, and core plugs (also known as frost plugs) are the plugs used to close openings left in the casting where sand cores were used to form those passages. Since a plug that seals an oil passage is, by definition, a core plug, the oil gallery can be described as a type of core plug. In other words, the plug that ends or seals an oil gallery is a core plug, which is why this statement is considered true.
