Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The installation procedure is identical for the two cylinder, the three cylinder and the four cylinder engines. The illustrations show the four cylinder engine.
Clean all parts. Ensure that all ports, all coolant passages and all lubrication passages are free from debris. To inspect the cylinder head, refer to Testing and Adjusting, "Cylinder Head Inspect" for further information.
Inspect all of the valve seats for wear and for damage. Refer to Specifications, "Cylinder Head Valves" and refer to Testing and Adjusting, "Valve Depth - Inspect " for further information.
