Now after i swaped to a UKDM SR20DE (high port) I'am having problems with oil pressure. The engine was disasembled, cleaned and has new rod bearings. The engine is equiped with a oil pressure sender unit.
Now as I start the cold engine the pressure goes up to 4bar. When i rev up the engine it stays there. Now when the engine heat's up the pressure goes down to 1 bar when idling. And when I rev it it goes up to 4bar. That looks ok. But now when i'm driving it happens some times that the pressure goes down to 1bar or less when driving and 0bar when idling (the gauge does not move) but the red light does not come on and the engine runs normal( no ratle from lifters or chai). Now if I turn the engine off and back on again the pressure is normal gain.
The pressure is specified: not less then 0.78bar when idling and not less then 4.5bar at 3000rpm.
What do you guys think? Is the regulator giving me trouble? Now i've changed the sender unit and will see what happens. But when the engine was cold the pressure was 4bar again and when i reved it stuck there...
What else could be wrong? Does anybodie know the pressure when the light comes on?
