Oil leak near intercooler?

Took the bumper off today and spotted this...

Large oily build-up around the bottom of the intercooler, but ONLY on the passenger side.

O-Rings were done ~25k ago, but they were ok when changed.

Is my intercooler shot?

If your intercooler was damaged you'd be permanently down on power as the turbo won't be able to pressurise the system, check your o/rings and the elbow for alignment then clean off the crud as that could be residue from the previous leakage.

O-Rings were fine...

I am down on power, fwiw... 153hp with a Synergy, EGR Bypass, Decat etc, whereas other owners get 165+

When the o-rings were replaced did you use viton seals? also did you make sure it was pushed home correctly as it can be quite difficult. Apart from any wear/cracking/puncture in the hoses I can only see the seals causing this fault. Cheers Paul.

As TSAUTOS said, clean off the oil. If you check it then it won't be long before you'll see exactly where the leak is from.
If it was a pinhole in the rad then araldite will seal it easily.

Otherwise the seals are shot or moved and need fixing.

I had a similar issue.
It turned out that when the top pipe was back in place, lined up with the bolthole it was not fully pushed in and still leaking.
I cut the hole in the pipe so it became a slot instead and used a large washer when refitting. It only sits 5 or 6 mm deeper but cured my issue.

Good luck
