I have to rethread my oil drain hole and use a pipe plug bolt to seal it. I notice there is a port in the drain bolt hole threads that leads to the clutch and I was wondering if this hole should be open or blocked by the bolt? thanks
 
Here is a picture of the port in the drain hole that leads to the clutch.
