CONSTRUCTION
An oil passage is provided in the intake and exhaust camshafts. The intake side is for lubricating the camshaft timing gear assembly and the exhaust side is for controlling the camshaft timing exhaust gear assembly.
Together with the use of the No. 1 valve rocker arm sub-assemblies, the intake cam profile has been modified. This results in increased valve lift when the valve begins to open and before closing, helping to achieve enhanced output performance.
