Took the truck back from the dealer. They "cleaned" the engine and replaced a cover. One side of the engine is now shiny. Great! a few days later the truck started to vibrate, check engine went on, few other things. I Brought it back to the dealer. They installed a spark plug incorrectly. They fixed it. I didn't have the chance to see whether the oil problem was gone yet.
