The Toyota K series is an inline-four engine that was produced from 1966 through 2007. It is a two-valve pushrod engine design. It was originally built from the Toyota Kamigo plant in Toyota City factory in Japan. All K series are non-crossflow engines – the inlet and exhaust manifolds are on the same side. They have cast iron blocks and aluminium alloy heads, with a crankshaft supported by five main bearings. K series motors have both hydraulic tappet or hydraulic valve lifters, solid lifters and 1.5 ratio rockers with an adjustment thread for tappet clearance. 7k engines were released with only the hydraulic valve lifters from factory, whereas 4k and 5k engines were made with both hydraulic and solid lifters (depending on year and which model vehicle.)
