Has anyone got advice or preferrences as to how to set the oil pressure relief valve (850 Commando Mk1)
I know that the professionals like Mick Hemmings prefer to use the absolute minimum of shims in the valve to reduce the pressure in order to minimise oil leaks, claiming that there is still plenty of flow through the crank.
Far be it for me to question such renowned experts but it does seem a little odd to reduce the overall oil pressure just to minimise oil leaks. I am concerned that the crank and bearings always have good oil flow quantity and pressure. Oil is the most important bearing in the engine.
Factory seem to set these valves with 5 shims between the spring and cup and imply that there is no adjustment needed. The relief pressure is set at about 45 psi.
I guess the only way to check it is to rig up a guage somehow. Any views?
