Sad news

The radiator core on the Whitcomb needs to be replaced. That's water running down the front of the radiator on the whole right side.
I put 4 buckets of water in to see how the patch on the bottom was doing. There was a place in the rear of the core where 4 tubes are leaking badly. I decided to fill it up and see if there were other leaks. I connected all the radiator hoses and filled up the radiator. The whole top header of the core is leaking badly. Water poured over the front of the radiator.
Replacing the radiator is a big deal. It needs to be removed with a crane and put on a flat bed truck. It is too big for a pickup truck. The tanks need removed and taken to a shop and welded up. A new core needs to be custom made ($$$). The top and bottom tanks need bolted on. Then the radiator and hood need replaced using a crane.
