Ok so for a while I've had a small oil leak coming from my crank pulley seal, but that has now been replaced. But, my oil pressure gauge is spiking.... It goes from being where it should be, and spikes between there and the red zone, but only when I am stopped. As soon as I give it any gas it goes back to normal or if i put it in neutral or park it stays normal. My oil is not low at all and it was just changed about a month and a half ago. If anyone can diagnose this it would be appreciated!
