Abstract
A Lifter Oil Manifold Assembly or LOMA has a metal deckplate with a non-metallic valve mount/stiffener having elastomeric seals on the surface contacting the deckplate. The electrically operated valves for controlling flow to individual valve lifters are mounted on bosses formed on the valve mount/stiffener. A bracket retains the valves on the valve mount/stiffener and the valve mount/stiffener on the deckplate when assembled on the engine by through bolts.
