Ce qu'en dit le mamuel d'atelier:

Pressure, engine warm at normal operating speeds ........ 1,76 - 3,87Kgf/cm2 (25 - 55 Ibf/in2)

temperature.
5. With engine running at idle check oil pressure,
which should read 1.76 bar (25.87 lbf/in2).

displacement gears.
Excessive crankshaft bearing clearance.
7. If excessive pressure is indicated it can be

Sorry c'est en grand-breton

En clair si c'est moins de 1,76 bar il faut s'inquieter
