NEED HELP
I may have missed a comment or 2 aobut riding this thing but if you haven'y been in water thenit most likely came from internal. If it hass been sitting the waterpump seal could be bad. I have replaced the oil and water pump seals in 400's on several occasions. The weap hole can get stopped up and the coolant can push by the oil seal and go into the counterbalance.
