Oil Plug gasket

or just ogre hands like me

If you can its good to use torque wrench on fill plug.
I set mine to 27 ft-lb torque until clicks then warm up the engine check oil level and then try torquing to 27 again until first click. Usually I get like 1/8 of turn extra when engine is fully hot. You can requse that washer once twice but afterwords you should change it. Its not made of metal. I was thinking about going with copper one to be safe.

 

would this explain the small drop i had on my oil plug? it also looked like oil was all over the pan. Im not sure what this means.
