The old saying it has to get worse before it gets better. The water was gushing out the muffler after a drive. I took off the cylinder head and tore it down and took it to a machine shop. A hole in the exhaust manifold was the problem. Now I gotta get a new head. Looks like the defender will...

I think the part I failed to mention is when this started I still had antifreeze in the system and the water leaking from the muffler was green. It was being driven 15km one way to work, which should boil out any condensation. The part I'm having trouble wrapping my head around is why after it...

haha, I wish. If you look at the picture I attached to the original thread you will see where the water is dripping out of the crack in the muffler.

So I have more to add to the complexity. I let the Land Rover sit a couple of weeks. I had to drive it over the weekend and it did not use any water. I drove 20 miles or more. But 2 weeks ago after driving it 10 miles home it used a gallon of water and water dripping out the muffler after it...
