If you have a full flow heating system, plumb it in series. If your heater has a valve that shuts the flow to it when you select cold air then you don't have a full flow system so you'll need to plumb it parallel.
However, if you have an engine oil cooler that is water to oil heat exchanger based, you may be able to find the return line from that and use that as your feed into the top of the vap and run an extra hose back to the block. This is what i'm doing on my 827s at the moment.
This means you'll probably still need a cooling system diagram though.
Re the manifold, my apologies but i haven't had a chance to get to the garage and have a rummage for it yet, i haven't forgotten though! Simon may beat me to it yet!
Thanks Dave, looks like you were beaten to it. At least I now know what straws are
Not sure if my system is 'full flow'... the nearest I can get to a drawing is here: http://lushprojects.com/bongopartsmk2/c ... mgno=.html
No worries Colin, had a brief look at that and i can only say it looks truly awful!
I can't see a valve to stop the coolant flow to the heater matrix in that diagram but i think there is at least one more part of the diagram to show the full system - think you'll have to get down and dirty with your engine bay and look to see if there are any valves of any description on the hoses feeding the heater matrices. I imagine it's pretty cramped under the bonnet and the rear heater matrix isn't particularly easy to get to so good luck with that!
I also now have a much better idea of what straws are and it's got me thinking. Future use though as both my V6 conversions are single point mixer for now, several reasons but cost and availability of second hand kit, tried and tested conversion on many other 827s and a few other similar reasons for going single point mixer.
However in the fullness of time, i do want to go injection on at least one of mine. I've just seen Simons comment about the King system and unless i'm reading too much into it, he seems to suggest the King system isn't necessarily the best choice for some V6 applications.
Given my own level of knowledge, experience, expertise etc, come the time to think about an injection system i think i may well be having a chat with him, plastic at the ready!
