As long as it's threaded straight and tightened (hand tight to stop) then no issue would not be torque. Just in case, you might want to have your girlfriend/wife/partner tighten it down for you

Looks good to me, except all coolant below. Without residue on bleeder valve I definitely suspect it's the cap leaking it. Get a new one and it should solve your problem. If you buy from local dealer it'll probably run ~ $35. If you buy online from Sunset or Suncoast Porsche it'll run much less (it was ~ $15 in '06 when I replaced mine).
BTW, what does your cap look like underneath? Like the one on the left or right from my pix above?
