Mini Oil Pressure Problem

[alessioblaupunkt]

There must be a minimum of 4 and a maximum of 8 oil change in this car.
Between oil change we don't know what was the oil level and no one of us know if the customer pour some non approved liquid in the engine like:
mechanic liquid ,clean engine ,stop oil leaks ,hydraulic lifter repair ,cure all issue
Is the car first hand or 2nd, 3rd...

Its second hand, but like i said, its not a pressure loss cos of knackered shells, they're like new! Gonna remove the filter housing today and see if that sheds any light

Was oil pump knackered by oil filter

Pressure relief valve letting by too soon, don't know if it was because of debris/damage or just a weakened spring, but I know curiosity will make me take it apart when I get five minutes!
