Hmmm, hard to tell where water originates based on the drip. Weep hole is common at this mileage. Of course check all hoses- would be well worth having an indy check it out if you can't locate it which will be very hard without a lift or dye.
If it is the dreaded weep hole, as mentioned the American made All German product is an excellent alternative ($1,600 installed at All German in SoCal vs $9,000 to have the dealer tear the engine apart and repair with the same defective design).
Hoses are a breeze relatively speaking, hope it is that.
