Hello!

What should I do with the outlet on the M10 valve cover? Currently it is venting straight into the engine bay. Engine has a Weber carburettor fitted.

1) Should I use a breather catch can/filter?
2) Should I just run a long hose to underneath the car and let it vent onto the road?
3) Do both the solutions above need a non-return valve?

the pipe was connected to the airbox without a check valve, the carburetor was supposed to suck the oil vapors,
if you leave it disconnected it will dirty the engine compartment, I put a small filter on the valve cover

Thank you, appreciate it.
