Topic: Oil leak on 2009 I30

I have an annoying drip drip leak from my plastic oil filter cap.
I have re-torqued it at 25 lbs/ft but it still drips oil.
I have tightened it a little more and it leaks and I have loosened it slightly and it still drips.
Has anyone else come across this on the I30.

Many thanks in anticipation.
