Hey guys! After quite the hiatus, I'm back from the Unemployed life...
Anyway, my question is this: My Pickup (2005 GMC Sierra, 5.3 V8) is having an issue with low oil pressure when starting cold. The lifters tick a little and then slowly the oil pressure reads normal after several miles at normal operating temperature.
Anyone have any ideas? I am thinking about trying some Auto RX http://www.auto-rx.com/ to see if there is some sludge gumming up my pump or sensor. Any help/ideas/experiences are greatly appreciated! Open to many things, would LOVE to do this on the cheap.
