First of all be very careful when rotating these parts now as brass is not nearly as strong as steel.
Only rotate these parts when the heater block is heated to around 180C so that any plastic in there will not act as "loctite". No need to go hotter than 180C as that can turn PLA and ABS into a kind of caramelized glue if you leave it hot for hours but 180C is pretty safe.
Teflon tape is fine. It has a glass temp of around 250C but it should be fine up to even 300C as a thread lock so the answer is "yes".
It may be that you didn't quite assemble it correctly. Your nozzle should not be touching the aluminum - there should be a very tiny gap - maybe 1/2mm such that you know for sure that the brass nozzle is touching the brass threaded pipe.
Years ago (more than 2 years ago), Ultimaker used to supply about 1 meter of ABS filament with the kit. The idea as to initially print with ABS such that the ABS would leak out through the heaterblock and nozzle. This would help clog up any leaks. Then I'm guessing you follow that with some PLA at "low" temperatures - no hotter than 220C I would think. After printing 40 hours of PLA like that the ABS should turn into a kind of glue. But I never had to do this.
If the leak is slow enough, eventually the PLA will cook into a glue and the leak will stop. After 5 or 10 hours of printing.

S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
