Antifreeze coming out blow by tube
 

I blew a head gasket and fixed it a few weeks ago. I noticed the blow by tube would have a drip of the green antifreeze coming out. Should I worry about it?

"Would have" or "does have"? If you replaced the head gasket and changed the oil and filters and there's no more water in the crank case, I wouldn't worry about it.

Could be residual from the pulling apart ..... Or a cracked head ...
