RE: Low Oil Pressure Indicator Light on 86 4kcs Q

That would be my guess if it is not the senders.  Yes you can pull the pan and 
clean it.  Just drop the front 2 bolts on the subframe it will drop about 6", 
which gives you room to remove the rear bolts.  You will also need to remove 
the aluminum casting that blocks the rear bolts.

  
>-Oil pressure relief valve defective.  (I do not know what this is)

Not sure there is one.

>permantly on if this was the problem?) Is this the symptoms of a bad oil 
pump?


Very serously doubt bad pump.


>-Worn main or big-end bearings.  (I do not know what this it)

Not sure why this would cause low pressure.

You should buy a $12 pressure guage and see what the pressure really is.  If 
it is alright than it is either the oil pressure control unit or the high 
pressure sender.  FIX IT BEFORE DRIVING.  Or not and you might have an excuse 
to do a turbo transplant.:-)
