Once you torque it (once), score the shoulder of the cap/cover in alignment with the seam on the housing. Then tighten it to that point in the future and you don't need the torque wrench nor have to worry about overtightening it.

Hopefully the dealer didn't soak you too badly for the filter assembly.

(BTW, you're changing oil too frequently; if you're going to do that you may as well use dino oil and paper filters and save some money.)

Good luck.
