I have moved to replacing the following with new Genuine Porsche parts while I am in there fixing the leak:
PS pump (Luk OEM same as the Genuine Porsche ) + upper and lower reservoir. All O-rings.
Return Line
Pressure line
TuneRS 4' Under pulley + new belt
Possibly PS Cooler
Will post results next once completely for anyone needing to do the same in the future.
Thanks to everyone who chipped in with ideas.
