Hi guys i've been doing some work on my car recently and I was inspecting a pipe that had caved in and noticed it was split.
The engine is a 1993 ABF code.
Basicly the pipe that's split runs from the bottom of the box arrowed, to the engine block. I'm no too sure what it does, or what it's called. Can anyone shed some light on where I could get one?

This picture is not my engine, if only lol.
