Toyota K engine

The Toyota K series is a family of inline-four engines that Toyota produced from 1966 to 2007. It is a two-valve pushrod design with a cast iron block, an aluminium alloy cylinder head and a crankshaft carried on five main bearings. The inlet and exhaust manifolds sit on the same side of the head, so the layout is non-crossflow. The family began with the 1.1 litre K and grew through the 2K, 3K, 4K, 5K and 7K, with hydraulic or solid valve lifters depending on the version and the vehicle. The engines powered small Toyota cars and light commercial vehicles such as the Corolla, Publica and Starlet, and several Daihatsu models, and the series was originally built at the Kamigo plant in Toyota City, Japan.
