Hi, so have been having a few oil pressure issues on the dash at least, have hooked up a mechanical oil pressure gauge and truck sits between 50-60psi at idle and when left running for over 20mins and oil heats up it only drops to around 45-50, but on the dash it starts at 30 and then gradually drops down to 0 once engine warms up, and then throws the check gauges warning light. Have changed oil just yesterday as well and that hasn't changed what I'm seeing on the dash. I don't think it's the bottom end bearing as there is no engine noise and mechanical gauge states no actual loss in oil pressure. Have also replaced the oil pressure switch behind the dizzy. Any ideas what could be causing the issue? All help appreciated.
