Has anyone not using the water outlet from the inlet manifold had any adverse effects.only my new manifold has not got any water pipes and the flange is a bit thin to tap a pipe thread in it,is it O.K to leave out the the bleed above it also.I am pretty sure some of the webber manifolds omit these pipes but I dont want to knacker my new engine.

I don't use the bigger water feed on the manifold but I do use the little bleed, run to the top of the header tank, to clear any air trapped there.

Water connections I use (ard race with this setup) are:

Water pump main outlet - feed to rad bottom connection

Thermostat housing main outlet - feed to rad top connection.

Rear of cylinder head - block it off

Main manifold connection - block it off.

Fit a header tank with pressure cap into the top hose if your rad doesn't have a tank/press cap.

Run the bleed from top (at front) of manifold, to top of header tank

job done, very few hoses needed.

You can do it that way as well, doen't really matter.

I was trying to keep it all as simple as possible, and it certainly works fine as I have it. If you think about it its no different to having no header tank and an old style radiator with header built in as the top tank.

In fact in my first proper XE installation with throttle bodies and management in an Opel Manta way back in 1995/96 that's exactly how I did it, water pump straight to bottom of rad, thermostat housing straight to top of rad and a bleed soldered into the very top of the rad and fed to the inlet mnaifold bleed.

here's the tank in the top hose on my locost:
