  • Cast aluminum alloy cylinder head with integrated timing chain housing and camshaft bearings
  • Five bearing single overhead camshaft
  • Two valves per cylinder
  • Roller finger cam followers
  • Hydraulic lash adjusters
  • Laminated (two layer) steel head gasket
  • Structural aluminum oil pan
  • Plastic intake manifold with integrated throttle body including throttle position (TP) sensor, idle air control (IAC) valve, manifold absolute pressure sensor with integrated temperature and manifold absolute pressure (T-MAP) sensor and fuel rail with four injectors
  • Four-into-one exhaust manifold
  • Crankshaft driven oil pump
  • Lightweight plastic coolant flow control housing with integrated double acting thermostat, coolant bypass and mounting boss for the engine coolant temperature (ECT) sensor

Cylinder head

The five bearing camshaft runs directly in the aluminum cylinder head.

An additional reference cam is provided for the camshaft position (CMP) sensor.

The cam followers are supported across the hydraulic lash adjusters and valves and the camshaft operates the cam followers through their roller bearings.

This has the advantage of lowering friction and therefore increasing durability.

The use of hydraulic lash adjusters removes the need for valve clearance adjustment.
