Just top end and rebuilt the waterpump. Connecting rod had no discoloration nor excessive play. Replaced waterpump shaft - rust had built by one of the seals and had worn the inside of the seal down causing the leak. It would drain the radiators overnight into the transmission, until there was nowhere left for the coolant to go.
There's a good chance some metal and made it into the crank bearings so I am definitely playing the lottery there. If it starts to make any unusual sounds the cases are getting split asap.
