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.
