Hi all, Just had a roadworthy check and the fella said the fan isn't changing to the screen. He said the controls are vacuum operated. I have had the engine out and in recently, does anyone know which vacuum line goes where, in case I stuffed it up?

AFAIK there is only one back line to the controls from under the bonnet. If it is off then it should only blow on feet. Check the y joint near the TB also check the line to the vac ball under the guard.

I'd start at the TB as that y piece are easily broken. A slight yank on the hose is enough to snap them.

If the hose under throttle body comes off, you often hear a whistle. I think that one goes to purge valve. There are 3 hoses at back of intake manifold on Ecomoo. One big one for brakes and 2 little hoses.

Cheers, one little hose goes straight to the firewall. I took him off and plenty of vacuum at the manifold, so I'll have to investigate that one. It has a round plastic element, for no better word in that line... what does it do?

It's a "One Way" valve.

Got it sorted, the vent control had a broken clip through the center of it and the unit jumped it's lug and gave limited vent control. I was able to put a small screw through the center to replace the broken clip and she is working well.
