Having a dry sump system is great. Depending on where your dry sump tank is located as to level with motor or above over a period of time the oil level will rise in the crankcase.
Where am I going with this?
If you store or park your car for the winter you may want to have a shut off valve or remove the inlet line to the pump to prevent oil seeping into the crankcase.
I known people to have a dry sump system store a vehicle for months and go to start it and when checking the oil level they add a few quarts/liters only to hydro the engine when firing or once the pump begins to scavenge they have excess oil in the tank.
