The intake valve diameter is a 32.2 mm the exhaust valve diameter is a 27.8 mm. Valves are actuated by the shim-less valve solid lifters/tappets (the adjustment requires replacement them by new). As was noted earlier, the head has 16 valves or four valves per cylinder (two intake and two exhaust valves). Camshafts are covered by a plastic head cover. The intake camshaft drives the exhaust camshaft by a gear. The engine has a timing belt for driving the intake camshaft only. There is a steel-laminate type head gasket between them. The aluminum 16-valve DOHC cylinder head is mounted on top of the engine block. The pistons are cooled and lubricated with motor oil sprayed by oil jets at the bottom of the engine block. Also, the engine was equipped with the high-strength connecting rods and aluminum alloy pistons with resin-coated skirts. The crankshaft pulley has a torsional rubber damper to reduce noise and vibration. Inside the cylinder block, there is a forged crankshaft with eight weights and five main journals. The 1KD-FTV engine has a cast iron cylinder block with two counter-rotating balance shafts driven by a gear on a crankshaft.
