Excuse me for sounding dumb. But what is this tube circled in the picture, and should it be leaking oil (or what looks like oil)? This is on the driver side of the truck.

It's the intercooler tube and having some oil residue in or around the fittings is normal because the crank case is vented into the intake. May people modify the crank case vent to vent into the air to prevent this from happening.

If you have a stock truck check your oil level to make sure itís not overfilled due to fuel dilution

also check the flow plug grommets for oil leaks.

Sorry for not replying back sooner. So to answer some questions, my truck is stock. the oil level is normal. But I've noticed that i dont hear that turbo whistle when i get up on the pedal. Im going to replace the intercooler boot, and clean out the turbo with a spray cleaner. And see if that changes anything. I don't notice a change in boost on the gauge. I'm also not getting any error codes. Correct me if im wrong, but in believe the tube I'm looking at is the hot side?

yes, the lower connection is hot side.

these boots get loose so try tightening both ends of the intercooler down.
