Cr 170 Oil leak

At front of engine on the block behind dipstick there is a black plastic joint bolted to the block with two pipes going to it.it is quite hard to see it from the front of the engine. It is not covered in a lot of oil just slightly damp and shiny when I put a torch on it. Is this anything to worry about is this normal ? What is it is it breather pipes for engine ? (2010 cr170 vrs).
