Hi all, as above I've got two breathers on the engine as you stand at the front of the car, left side low down at the back of the block, I was going to pipe that to a catch tank. But what about the one on the right side of the engine near the oil filter, it has a chamber on it.
Would this also need to go to the catch tank or can It be left open?
It's hard to get a pipe on it because it's up against the inlet.

Any advice on this would be nice.

Cheers andy.
