Abstract
An oil control valve assembly for an engine is provided that has a control valve with a valve body, and a manifold that defines a control passage in fluid communication with a valve lift switching component and an exhaust passage for exhausting fluid from the valve. The control valve is controllable to selectively direct fluid from a supply source to the control passage to actuate the valve lift switching component. An elongated tubular member is positioned adjacent the engine component and is operatively connected to the exhaust passage such that fluid flows from the exhaust passage to the elongated tubular member and through the elongated tubular member onto the engine component.
