In the pic is this correct the breather vents from the crank case and also a pipe on the manifold? will this not cause a boost leak as there dose need seem to be a one way valve or anything

 

There's normally a one way valve in the small hose, but the breather pot looks right, should have a hose that goes back to the airbox

 

There's no longer an air box so it'll be atmosphere vented I just need the 1 way vale then

 

Yeah just need a one way valve I've just got one node eBay make sure you don't drove on boost until you get one tho as this can cause big damage to your piston rings and cause the filler cap to blow off and splat oil all over the engine bay

 

The guy wiring on the cars gonna blank it off, you got an item number for the valve?

 

Item number is 130974315888 I got the 6mm valve but it's a bit small probably better off with the 8mm
