Default ZVH Breather Return

I'm new to ZVH's...

When replacing the std breather setup on a ZVH engine (FRST in this case) how's best to route the return from a Bailey tank? The only obvious ways I can see is to either T into the Rocker-to-block breather hose at the bottom, or the Turbo oil return which is at the front of the block...

...at the moment i've connected it to a bottle which seems ok but the idles a little lumpier than it was before.

Mine's already got that rear return I think and being used for the n/s rocker cover hose as per the original 1.6 block. Someone's suggested on my other thread using an ERST breather instead of a FRST which can have both rocker cover outlets going to it and still return to the bottom one you mention.

That link looks very interesting though, thanks for that!
