A few general questions about mechanical bits and bobs:
1) The breather pipe that goes to the airbox and blows oily air into it. Why?2) The other one that goes to what looks like the inlet manifold. Why?
3) Where does the pressure in the rocker box come from?4) I assume Vacuum is generated by the pistons trying to suck air in on the intake stroke. How's it tapped off for the brake servo etc.?
Cheers.
