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.

The 2Y engine is an OHV, eight valve construction just like the 1Y. It shares that engine's {{convert|86|mm|2|abbr=on}} bore, but stroke is increased to {{convert|78|mm|2|abbr=on}} for a displacement of {{convert|1812|cc|L|1|disp=flip}}. There are also 2Y-J and 2Y-U engines with differing emissions control equipment.

  • OHV, eight valves
