Help diagnose oil leak

[JayShopper]

2014 Yukon has been dripping off and on for the last few months. I am pretty sure it's oil. Sometimes it doesn't drip, and it's a very small amount when it does. Here are a few pictures down into the engine but I don't really know what I'm looking at.

Looks like a power steering pressure line.

Or Oil Cooler Lines. both ps and cooler lines on the driver's side

When mine did this, it was the front main seal.

Well it has a myriad of issues...
1. PS line is leaking slightly, which he said is recommended to be replaced but not my main issue. ~$300 plus another $190 for the PS fluid service

2. Engine Oil Cooler Hose needs to be replaced - $600

3. Engine Oil Pan Gasket - $650

4. Valve Covers (L and R) - $300

Definitely looks like the engine oil cooler lines just as @Foggy said.

The stock lines are known to fail right at the connections circled here:



You can see the oil seeping down the lines coating the rubber flex lines and dropping onto the black plastic skid plate.




How many miles are on the truck and how long do you plan to keep it?

I don't go to a mechanic often but these prices seem reasonable. Especially if it's a shop you trust. Did he say these are definitely all the leaks or fix these and recheck?

I trust this guy and he's done work on other cars at reasonable rates. I did everything but the PS lines which he said were not really necessary.

Truck has 156k and I like it and will probably keep it awhile. With gas prices the way they are (I am in NorCal) it stings to fill up though, so I've thought about dumping it for a plug in beep-beep for the vast majority of my trips which are errand/kid related.

Near Byhalia, I'll take care of ya!
