Hi Tezzaworld, Im having problem with my 2002 3SGE motor. The oil pressure goes down to the last bar when the engine warms up, but upon starting when its cold, the pressure level reading is normal, and responds well for about 5km drive then it starts to drop. Oil level is ok from the dip stick and the car is driving well, no strange noises coming out from the engine. I was running 5w40 and have changed to a thicker oil 20w50 thinking it will solve anything but no change. What could be the issue?
