HELP!!! oil pressure
When i started my truck up today everything was fine but once it got warmed up the oil pressure gauge would drop when i mashed the clutch to stop. It also drops as i let the clutch out. But goes up to normal when i race the engine and when im driving down the road. I checked the oil level and its full. Any ideas on whats wrong?

My 90 351 started doing that overnight, showed pressure until rpm's dropped close to idle, then would drop to nothing. The sender in these years is just a switch and triggers at about 7 or 8 lbs. I put a mechanical gauge on it and showed about 40 lbs cold then dropped to about 5 lbs hot. About a week later I developed a knock and ended up with a new motor.
