Toyota Y engine


The Toyota Y engine is a series of overhead valve straight-four petrol engines manufactured by Toyota from 1982 through 1996. The Y engine has mostly been used in commercial and off-road vehicles.
The valve arrangement from the Toyota K engine is interchangeable with this engine.

1Y

There is also the 1Y-J, with the "J" suffix meaning that the engine is built to meet emission standards for light commercial vehicles.
  • OHV, eight valves
