ashbuster Posted January 27, 2013 Share Posted January 27, 2013 just wondering why they take a braided line from the intake by the filter to a catch tank (black lines) Quote Link to comment Share on other sites More sharing options...
DaveR Posted January 27, 2013 Share Posted January 27, 2013 That's a breather hose for the catch tank, mirroring the stock setup (so the hose feeds into the intake pipe, not away from it). A bad idea, so I've been advised... Quote Link to comment Share on other sites More sharing options...
ashbuster Posted January 27, 2013 Author Share Posted January 27, 2013 ahh nice one, just wondered because the catch tank had a filter on top so i thought it vents from there. if you were to add a catch tank to the cam covers you would just tap the covers and lead the hoses to the catch tank and then cap where they originally go to dont you bud?

DaveR Posted January 27, 2013 Share Posted January 27, 2013 As far as I understand it, yes. Plumbing the catch tank back into the intake raises the intake air temperature and allows a fine mist of oil back into the turbo, all of which lowers your fuel octane rating, meaning badness. I'm by no means an expert in this, by the way, I'm passing on the words of wisdom that I received when I plumbed my own catch tank in a similar way to the one above. I think it's technically a requirement of the MOT to have the breather recirculating, but (again, as was pointed out to me) it's highly unlikely that your average Mr MOT Tester would have the first clue what he was looking at if he popped the bonnet and was presented with that sort of engine bay!
