Renault Premium DXI low oil pressure what's the matter!

🔴 Hello everyone! They pulled a RENAULT Premium 440 with a DXI 11 engine to us for repair. At operating temperature, the internal combustion engine shows low oil pressure! We checked mechanically by measuring the pressure with a pressure gauge, thereby making sure that the sensor is working! We decided to flatter the pallet, after checking the liners and the pump, we realized that it wasn't about them, we also checked the rubber seals everything is in order!unscrewing the relief valve to check its operability, they found a crack through which the oil was drained into the pan bypassing the valve. Also, before the analysis, a complete diagnosis of the internal combustion engine was made, which pointed us to poor compression in the 6m cylinder!
In this video, you have performed diagnostics of the internal combustion engine, disassembled it and assembled it, and also launched the internal combustion engine!
Thank you all for watching!
