    So today was driving and when i was stoped at advanced auto parts my oil pressure light came on.. and my pressure dropped to the 0 mark... not good! wht is the culprit?? hopefully its nothing expensive :-( the truck is a 1999 silverado with a 5.3l engine in it. it has 184k miles on it and it has single in single out flowmasters on it and a Cold air intake. checked oil.. and added sum stop leak stuff just in case there might have been a link. The light only comes on after i stop.. and seems as though if i repeadidly tap the brake while stoped it drops the oil pressure faster. it could just be droping it when im stoped and have nothing to do with the brake but not sure. Any help would be great!
