Loss of oil pressure

Asked by Mar 17, 2017 at 10:28 AM about the 2003 GMC Sierra 2500HD Work Truck Standard Cab LB HD

Question type: Maintenance & Repair

Driving down road 15 or 20 miles oil pressure falls sets off check engine light and get valve chatter. Turn off and re start pressure right back to normal for awhile then happens again. Truck is a work truck with 241000 miles on it. Ideas?

1 Answer

Changed oil and filter went down road no problems got off highway made several quick turns and went thru two roundabouts back on highway. Oil pressure fell to 15 pounds. I pulled off road let it idle it then went to 5 pounds with chatter turned it off waited 10 seconds started back up pressure went to 40 pounds. Drove back no problems, in yard drove a serpentine pattern and pressure eventually started to fall to 10 to 15 pounds. Stopped, at idle had 5 pounds with chatter. Shut off engine waited few seconds started back up to 40 pounds of pressure? Could something be in oil pan getting picked up and blocking draw tube?
