Can Someone Help Identify this Part?

Hi,

I've just a look under the hood and noticed some oil leaking from this pipe, the only problem is i have no idea what it's called so i can't really look for a replacement.

If anyone can help identity it that would be greatly appreciated as the last thing i need is oil leaking all over the engine!

It is the crankcase breather tube.

There's an o-ring inside that you could try replacing. Also, you could try a bit of Teflon pipe thread tape on the "threads" (worked for me).
