Richard, I am pleased that you have achieved a good result, in an economical way.
Is yours a Serpentine belt Rover engine? If it is then oil pressure of 2.2 Bar seems a little on the low side. I agree that is more about flow than pressure (which is possibly why cooling it is giving you the results) , but the later serpentine engines deliver about 2 Bar at idle and 3.5 to 4.0 Bar running at over 2,000 rpm. The gauge no longer measure actual pressure , but an electrical reading from a pressure sensor, so it is sensitive to all the electrical contacts being clean. You might want to look at that.
