Hi there, I've got myself a rather fantastic coolant leak. It literally drips out as soon as I fill the expansion tank.

The leak is coming from somewhere under the air inlet manifold.

It's dripping down onto/around the coupling for the thermostat and coolant delivery pipe (?) that runs along the engine block under the inlet manifold. Video in link: I'm getting a cheap endoscope to try see more as I just can't face pulling the manifold off. But is this gonna be a cracked cylinder head/gasket that's letting this by? Or possibly something not so terminal....

Probably just his metal pipe that runs across the back of the engine, or one of the connections where rubber hoses join onto it?

Can't view your video unfortunately.

Seems like wishful thinking that you'll get far without removing intake manifold. That's probably not too difficult, especially if you can get some light behind there and have a 'mirror on a stick'.
