    Got a boost leak somehwere and there is oil on one of the pipes with under the manifold where they crank round on the left side.

    I have bought the Forge silicone breather hoses and the N75 and ancillary boost hoses to be fitted, and already have 007p, Cam cover breather hose and TIP fitted. What I want to do now is get the other miscallaneous pipes done in silicone (at least the ones which are on their way out).

    I have heard that 3/4mm is are the main sizes, are there any other sizes I should be buying too?

    She's booked into to APS week after so want to take the silicone with me too and get these boost leaks done once and for all!
