I'm not exaggerating when I say this. If they took used motor oil out of the oil drain tank at jiffy lube when the truck was new, then put it in the motor, 20K miles later it wouldn't look that sludgy. Something wrong is going on. That pan needs to come off to see if it matches what's going on up top. You should also read my thread about checking the date code on the block. It'll then tell you if it's an '07 block or not. The heads will also have a date code cast into them that should tell you when they were manufactured. Heads are typically made within a month of the engine. https://www.performancetrucks.net/fo...d.php?t=415201

Something is definitely not right. It does kind of look like it was full of water mixed with oil. There is no way that has less than 5k miles unless that thing was seriously abused.I would get a closer look inside that thing.
