Drill / file a suitable hole in the new intake tube, fit a rubber grommet and insert the breather tube (into the grommet that is...).
While you're at it, you can open up the end of the breather tube (where it tapers down) for an increase in breather flow (shove the closed jaws of a needle nose plier into the end, push and twist, the taper will spread).
Here's why you might want to do this:
In normal operation with an engine in very good nick the PCV will control breather flow through this tube (attached to the induction pipe), i.e. the plenum vacuum 'sucks' blow by gasses from the crankcase through the PVC, but in order for this to occur without the possibility of creating a negative pressure in the crankcase filtered air is 'sucked' through this tube from the induction pipe into the crankcase (to ensure that an airflow always exists through the crankcase).
With an older engine with significant blowby pressure the crankcase can become too pressurised for the PCV to adeqately vent the crankcase, and blow by gas will now not only flow through PCV, but also 'backwards' through the tube attached to the induction pipe then into the induction pipe (this is why the throttle body and the throttle body end of the induction pipe can get oiled up, i.e. from gasses coming from the crankcase). Opening the end of that tube fitting will increase flow, so crankcase pressure won't get quite so high, which is a good thing.
thanks for the info man, but i was only wondering what to do about the coolant line side of things the breather is sorted
i was thinking just get some brass, fittings and make something up or one full piece hose
Sorry, I now see what you've done with the new yellow breather hose in the photo above. It's just that all I could see amiss in the last shot was the open end of the stock breather tube.
I'd just ditch the metal section and use a longer section of new rubber hose to connect the coolant ports. Path of least resistance and will look fine.
