I am working on the 23 that I built for my son.
Have following symons,
Water in radiator is brown even after flushing with at least 40 gal water.
Radiator overflows while driving but temp is normal.
With radiator cap off it spews foam while ideling.
Can't pressure test cooling system because radiator has crack in one end tank that needs to be fixed but would like to do all repairs at one time.
Engine runs very well under all conditions.
Is this a head gasket or cracked head?
If so has any one had success with any of the additives that are supposed to fix head gasket leaks or head cracks.
