I Have A 89 Chevy Truck 350, I Start To Lose Oil Pressure As The Engine Heats Up. It Has About 100k On It. I Verified It With A Mechanical Oil Pressure Gauge. Any Suggestions?

Change oil pressure gauge first and if that doesn,t work you my have an oil pump problem.Mileage today doesn,t mean anything today a lot of problems with even lower kilo. Cars & truck.You can remove oil sensor from motor and attach a oil pressure gauge into it to to see if it is reading correct. Hope this help.
