39 Dodge engine start up

[garyp]

Just started my engine for the first time since being rebuilt and noticed a little anti freeze leaking from one of the intake manifold bolts I only ran the engine for about 15 seconds then shut it down. What could cause that maybe the stud where it goes in the block is not seating right? I will not start the engine until I hear from someone I am really worried about this.   Thanks Gary

Some of the manifold studs penetrate the water jacket. Simply remove the leaking stud and put some pipe dope on the threads, reinstall it and you should be good to go. Same with some of the head bolts as they also penetrate the water jacket.

Don you just lifted a weight off my chest I was so worried it was something serious and I would have to tear the engine apart. Thank you

Also one or more of the water pump bolts goes into the water jacket .

If you were running straight tap water, these leaks would probably "take up" or stop within a few days.   Antifreeze solutions will make their escape more readily than water and will persist.   If it were mine, I would run straight water for a week or two then refill with the antifreeze solution.
