I’d bet 9x out ten leaks on the exterior of the cam covers are spark plug tube related. Clean them really well and replace the tubes, plugs and o-rings. Monitor. Prob good to go. Might want to do coils while you are there. There are a variety of things that can leak on top of the engine as well so it could be several things. The oil pressure sensor sits right above there and could be leaking. Most likely if there is oil in the tubes, the inner o- ring has failed, or the tubes have cracked. Porsche motors don’t particularly like sitting. Get the leak figured out and drive that thing to get some blood flowing.
