I'm currently fitting a boa in my capri but am not sure on where all the pipes go which are at the back of the engine, there I's a big pipe on the underneath of the plenum, a smaller pipe coming of the o/s cam cover and then the valve with another hose on the n/s cam cover, Any helpon where these hoses go would be very helpful

The big pipe with the pcv valve goes to the valve cover. the other valve cover has a pipe at the back and that one goes to the airfilter box.

The big pipe with the pcv valve goes to the valve cover.

I'm on about the pipe which I's right on the underside of the plenem chamber not the one on the cam cover with the pcb valve, i was thinking possible for brake servo?

There is no connection for the vacuum for the brakes.

There are 2 big pipes, one comes from underneath the plenum and goes to the valve cover. A other is on the back, underneath the plenum and goes to the egr.

For a vacuum connection for the brakes, you can use this one, if you dont use the egr (i would advise the use the egr system) or fabricate a t piece in this pipe.
