Has anyone connected up a breather system with the engine completely assembled. Obviously it would be a LOT easier with the head removed or at least the manifolds off to get to the bung under the exhaust manifold and the return under the inlet side (4x4 saff). Want to fit one before installing some power upgrades but don't really want to take the manifolds off if I don't have to. Looking at it I am struggling to even see where these connections are, let alone connect something to them. Thanks David
