Test procedure
– Increase engine speed further.
● At 2000 rpm and an oil temperature of 80 °C, the oil pres-
sure should be at least 1.5 bar.
● At higher engine speeds, the oil pressure must not exceed
5.0 bar.
If specification is not attained:

Note
Mechanical damage, e.g. to bearings, could also be the cause
for oil pressure being too low.
