Re: 2000 5.3 oil pressure warning

I hope its just the sending unit. I thought it was strange that I have had good oil pressure up until last night when it sat outside at -14 and wind chill of -48. I have never had any oil leaks and run 5/20 in it, but at 211,000 miles the cold would probably find the weak spots. I have heard of these pumps having a stuck pressure valve inside them also, that reroutes excess oil away from the out flow when overpressurized and back through the system. I am hoping the expansion of the metal from the cold is holding it open and it will be ok when temps reach 34 by friday. I am worried about the engine now that it ran that way for a good 15 min. My son drove it to work and back the night before and im not sure if it was this way then or not, he doesn't pay much attention to those details.
