Cheers Tony! off the top of your head do you know what size hoses the PCV lines are? mainly the ones that go to the intake, i think they have an ID of 10mm?
Also there is a line which runs from the power brake unit, to the intake manifold, do this have to be reinforced? as it sucks quite a bit, and thin tube just buckles under the vacum.
I have put a catch tank in today, and tube supplied has a big ID and too big to go onto the breather and intake, and like said above the tube i have goes soft when hot (its better quality than supplied though)
