Hello everyone. I have a strange problem with the engine(z22se). When the car is cold, at startup it takes 5-10 seconds until oil pressure builds up. When the vehicle is hot, it shortens to 1-2 seconds. The idle is steady At 5 bars, it drops to 3 bars when the engine get to working temperature. The maximum pressure is 4.5 bar and does not rais higher . Pressing the gas paddle at third gear, from 4000 rpm to 6000, the pressure drops to 3 bar. After that,In idle at traffic light, 3 bar. No engine noise,feel Powerful. I replaced two oil pressure clocks. The reading are the same. I checked and replaced the piston and spring of the Release valve of the pump. No difference. Can anyone help? I was advised to replace an oil pump. Thank you and good day
