I bought a 1946 Oliver 70 a few weeks ago. When I first brought it home, after a good run down the road, it started foaming in the radiator. It had white suds or foam blowing out of the radiator over flow. I tore the engine down and replaced the headgasket. After putting it back together, I flushed the cooling system once with radiator flush and 6 or 8 times with fresh water. The water looked brown/dirty when it comes out. With only fresh water in it, it doesn't foam up at all, everything looked normal. After I drained it again and added a 50/50 mix of antifreeze, the suds/foam is back again. I am not getting any water into the oil at all and it doesn't overheat. Any ideas or sugestions on what to do next?
