The CA is leaking coolant. Have circled where it is leaking in the pix. It is a dicast elbow, with a steel fitting pressed into each end. It appears the steel fitting facing the rear has rusted and has a pin hole. Area is wet, and although engine has not started for 3 weeks, have drips of coolant on the floor.

Any one come across this before. Thinking of using a plastic elbow, with some new hose ???

As assume you cant buy this fitting.

Thats only a throttle body warmer for japan's winter climate. We don't need it in Australia. Just bypass it, or block off either side.

There another one at the back of the plenum ..it's more risk than benefit. Just get rid of them.

You don't want to block off that intire part, just the small fittings coming off it that go to the throttle. The 1/2"(size?) pipe is the thermostat bypass and you still want that - although that is just the conclusion I came to with mine.

I just went through the same problems with mine, I got the 1/4" fittings brazed shut. One comes off that little cast elbow and the other one is where it re-enters the cool water flow on that straight pipe under the manifold. You can just bypass the one at the back of the manifold and run it straight into the turbo water feed line on the back of the head.

As for your leak, take it apart and if you're sure that it's the solid part leaking then either find another or get it sealed by the person brazing up for pipes. You might just find a bit of corrosion on the fittings that can be taken off and I can't say enough for getting exactly the right size hose and clamps. Mine was leaking because I'd used clamps that were too large and when they crimped down on it they pinched the house in a funny way making it easier for the water to get out.
