Toyota Y engine

The Toyota Y engine is a design that's a combination of the Toyota T engine, and the Toyota R engine, in a way that's similar to how the Toyota F engine is a design of the Toyota Type B engine, and the Chevrolet inline-six. The Y engine has mostly only been used in commercial and off-road vehicles.

The valve arrangement from the Toyota K engine is interchangeable with this engine.
