John,

I could be a blown head gasket or a cracked head.  Sometimes the cracks
don't open up till the engine is warmed up.

Why would a good-running JD A start frothing at the mouth?  After about 
10-15 min. of warming up an an easy idle the coolant starts foaming out 
from underneith the radiator cap (running over).  Looks like there's air

getting in the cooling system.....from where?  This tractor has the 
waterpump.  There is no sign of water in the oil or other exterior
coolant 
leaks.     Pulled the head and the head gasket looks OK.  The cylinders 
look OK too.       ????      John Wilkens
