MATERIAL

Item Specification
Motorcraft® SAE 5W-30 Premium Synthetic Blend Motor Oil (US);
Motorcraft® SAE 5W-30 Super Premium Motor Oil (Canada)
XO-5W30-QSP (US); CXO-5W30-LSP12 (Canada)		 WSS-M2C946-A
NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.
NOTE: Whenever turbocharger air intake system components are removed, always cover open ports to protect from debris. It is important that no foreign material enter the system. The turbocharger compressor vanes are susceptible to damage from even small particles. All components should be inspected and cleaned, if necessary, prior to installation or reassembly.
NOTE: The engine comes equipped with either a roller primary timing chain or an inverted tooth primary timing chain. The roller timing chain upper LH guide differs in design than the inverted tooth upper LH guide.
NOTE: Early build engine cylinder heads and fuel injectors differ in design than late build engines. Although these parts are serviced in the same way, the parts are not interchangeable between early build and late build engines. The level of cylinder heads and fuel injectors can be determined by inspecting the engine code label. Early build engines are built through 09/14/2010 (0S 490 BA) and late build engines are built on or after 09/15/2010 (1S 490 BA).
