* When oil reaches the back of the cylinder head, the oil gallery feeds oil into an accumulator chamber that is
located towards center of the head. The accumulator chamber is closed off with a pressed in core plug that has a
small orifice to act as a vent. Oil then travels down at a 45 degree angle from the accumulator into two passages,
one for the intake and one for the exhaust side of the cylinder head.
** The secondary camshaft chain tensioner is the last component to receive oil on the left cylinder head.
