3.0 Mystery Diesel Oil Leak

[daigljk]

My 2023 JT 3.0 Diesel with 14,500 miles has been leaking oil on my driveway for months. A drop or two every parking. Over a couple months my driveway is a mess. I parked at a new spot at work for a week to get a visual of the volume of the leak so I had some kind of reference when I took back to the dealership to be fixed. Attached is after 5 days. I've looked for the leak myself without much success. There just is no room to work on the damn thing. I saw lots of oil dripping off the oil cooler and most of the driver side engine is wet.

Took it to the dealer a couple days ago......they put die in.......ran it.....nothing. Ran it some more in the tech's booth......nothing, WTF They told me to come back in 300 miles if.......when.....I see more oil drops on my driveway. So frustrating. Any clues or suggestions on how best to id leak would appreciated!

climb under the car, look directly up from the drips on the ground and start following oil streaks backwards until they stop at some part of the engine that is exposed to oil?

The breather on the rear axle, based on the pic.
Oil on the driver side of engine could be from an oil filter change.

It's pretty easy to get some oil dye and toss that stuff in. Then give a week and use a blacklight to chase the trails.

Thus crap of putting dye in it to find a leak is special. Turbo feed and drain oil pipes are direct center of the engine in the back. If it's on the oil cooler it's likely a bad oil filter and/or cap. Could be a cooler but, unlikely.

Thanks guys for the feedback. Yes, I did try and trace the drops to find the leak but oil has dropped on the diff and other places making it difficult to trace the origin of the leak. Like I said, there definitely is oil accumulation on the oil cooler. I retorqued the oil filter several times over the months to no avail. Dealership changed the oil, oil filter and added die so we'll see what happens in 300 miles. I'll report back.

I should correct my spellings......dye not die

Update:
Dealer replaced oil cooler/oil filter cap assembly. 1 week later.........still leaking.
