Examine the pressure pipe between oil pump and cylinder block for tightness.
Note:
^
Also, mechanical damage e.g. bearing damage can also be the cause of too low oil pressure.
If a malfunction is found despite insufficient oil pressure, replace oil pump.
The oil pressure must not exceed 7.0 bar.
If 7.0 bar is exceeded:
-
Check oil channels.
Possibly the oil pressure relief valve in the oil pump is plugged.
