To help explain my problem I uploaded a video to YouTube because it wouldn't let me upload here. B16A oil pressure - YouTube The oil pressure climbs then drops exactly at 3k and stay at 60psi sometimes 65 or 70. I'm using a mechanical oil pressure gauge. The whole time I'm accelerating. Doesn't make a difference if I'm full throttle or barely accelerating. In the video I was light on the throttle. Motor is a JDM B16A first gen.
