When I start up my 2019 GS with dry sump, my oil pressure gauge takes a few seconds to register any oil pressure. I think I hear a solenoid engage and then the pressure comes up on the DIC. It takes two or three seconds to show oil pressure on the DIC.
Again, I hear a solenoid, like the sound of the A/C compressor coming on, (the A/C is off) it clicks and the oil pressure comes up. Is this normal? Isn't the oil pump always mechanically connected and pumping oil even at startup?
The oil pressure sensor is located at the front of the Valve Lifter Oil Manifold. Oil has to be pumped through the engine to the filter, then the oil cooler and from there to the valve lifter manifold so it will take a noticeable amount of time from the time the engine fires until the pressure gauge responds.
