If the oil is overfilled, you may be whipping air into the oil, with a resultant loss of pressure. 

Isn't the oil pressure sender/sensor, well below the upper surface of the oil?
Any oil that is foamed by the crank/rods, is well above any measuring device in the engine,
AND most importantly, the oil pickup tube is well below that surface and lubrication won't
be affected, unless the van is upside down.

Where oil foaming can be critical is during racing, very hard cornering, which is why they almost
always use windage trays in them.

Whether this can apply to the wbx 2.1 or not I don't know, but the man who owns Metric Motors
here in Utah, which has been in the business of producing high HP motors for sand rails, says
the reason they never have this foaming problem, with resultant starvation/lubrication problems
to the mains and rod bearings, is that the pick up tube is so low in the wet sump, along with the
windage tray, there is never a lube problem......unless the engine continues running when the
rail is wheels-up. He also said the oil temp and pressure senders are installed low in the sump
for constant, accurate reads.
