The Zuk has had a mystery water leak for a while, with no visible signs of water. So I just ran it until it got bad.
It eventually started leaving large puddles of water under the engine, that looks like it was from the water pump area.
Luckily I have 2 spare engines, so I pulled one and replaced it.
I left the timing cover off to keep an eye on the blue gasket maker, but given the crank is 3ft off the ground (measured), I might be lazy and keep it off.
