Hi Volks,
 
Last night my oil press idiot light started to flicker.  I have an '85
Westy.  It has a Mann Filter with 20W50 dino in it.  The original engine
has 161K on it.  I am about time for an oil change so that's what I will
do first, but I thought I would run something by you guys/gals first.
It started after several hours of driving so the oil temp was at
operating temp.  The light did not correlate with engine RPM.  It
flickered at high RPM but then it wouldn't do it always at idle speed.
The flicker was intermittent.  It seems to me that if it was an oil pump
problem the light would come on at idle and possibly go out at higher
engine speeds.  If that's true then the other possible problems could be
the sending unit or the wiring to the sending unit.  Where is the
Sending unit?  Is it under the shroud plate, driver's side? Thanks in
advance to all your thoughts.
