Any 10 weight oil (such as 10W30 or 10W40) will cause low oil pressure at
idle. The Rootes engines were designed for 20 weight oil. I use 20W50 (or
20W40 when I cen find it) and have no problems at all. Check your manual-it
says 20 weight.

The pressure relief valve releases excess pressure at high rpm. It is
common to dismantle the valve and shim the spring to raise the pressure
to 50 or 60 pounds. However, this will not solve the low pressure at low
rpm problem if there is not enough pressure in the first place. Common
problem is worn bearings.
You don't mention the actual pressures - the pressure will normally drop
at idle - is it below 20 pounds hot? What is the pressure at 3000 rpm?
