The plenum gasket has nothing to do with the problems that you are now
having. Also neither the rings or the valve seals have anything to do
with
oil pressure. If you are already running 10W40, then it is time for a
rebuild. The results from the test that you performed indicates that the
sensor is working properly and your engine is losing oil pressure due to
bearing wear. If you are considering replacing the rings, have them do a
full rebuild since they basically have to take most of the engine apart
anyway to do that and you need the bearings replaced anyway. Take it to
someone that you trust and ask them for a full breakdown of what they are
going to do.
