Its black, and flexible, and looks like its made of a hard rubber- my finger nails can dent it...
Looks lik theres a sealing surface on the top and bottom of it, and its broken on one side...


Any ideas WTF it came from?

it COULD explain the phantom oil leak coming from the front of the engine behind the main seal- the main seal itself isnt leaking, but theres oil on the join between the main sump and the block!
