2005 CTSV starting alarming overthe weekend "No Oil Pressure". Powered down. Oil volume and appearance looked normal. No bad engine sounds. I had her towed to a seasoned mechanic. After sitting 2 days, he took it for a ride and oil pressure began reading 37-41 on the guage after a mile. Said must be a loose sensor. Told me sensors are way behind supercharger and since she is "acting normal", drive her and don't worry. With every start she alarms zero oil pressure tha climbs to normal pressure after about 60 seconds. Needless to say, I'm worried. What do you think? Oil pump, sensor, ?????? Anyone else experience this?
