Am i right in thinking this is the breather pipe for the oil vapour coming from the engine to the intake? Its the small black pipe with the white line running down it.

I have my removed this pipe and connected my oil catch tank via these points but after a month i have collected a few spots in the bottom of the catch tank and thats it.

Do i have my catch tank connected in the right place?

Pinched the image from Google and added the arrow, sorry if its your car.

Correct, oil breather pipe.
