Yea, i hate to beat this dead horse again, but i cant seem to find an answer in my searching. 2015 Silverado 2500 HD 6.0 gas.. Purchased this used truck a few months ago and noticed at idle the oil pressure was pretty low, around 10-12 PSI. I finally changed the oil with 5w-30 dexos and wix filter, after a few hundred miles, i'm getting Engine oil pressure sensor problem (P0521). I just ordered a new sensor, it will be here in a few days... i'll replace it and remove the screen, hopefully that's all it is, since this is the cheaper/easier, i figured this was a good place to start. TLDR My question is, do these engines still have the same issues as the older 5.3's and the o-ring on the oil pickup? OR, are spun cam bearings more common? What are your thoughts? FWIW, the truck shows 117k miles, but the engine block is orange, to me this indicates its been replaced. any help is appreciated!
