As a comparison; an Hillman Imp engine 875cc/4  is 50lb square inch when hot,
Ariel Square 4,  25-35lbs inch  or above this figure;

Look send me an email I have a PDF FILE OF A COMPLETE STRIP DOWN & TECHNICAL INFORMATION!

On Mark 2 models,  the pressure release valve is located in the body of the oil pump!
