Old Freeze Plug Inside Block

So, was turning the block over on the stand to start on the lifters and heads. Heard a little jingle inside the block, and thought it was just the oil pump rod shifting. Was cleaning out the threads on the block and my rifle brush hit something inside that jingled. Come to find out there is a freeze plug in there. I would just pop out the outside plug and use a magnet to pull out, but being on the stand, very limited room back there, and most likely would have to put it on my crane to pull which would be a PITA.

Any issues with leaving the freeze plug in there? No telling how long its been in there. Worst of it is that I had this block cleaned and had new freeze plugs installed a while back. Maybe the machine shop did it..but too much of a hassle to haul it over there.

Thoughts?

I would try to dig it out personally, just beacause I would obsess over it.

I don't think it will hurt anything if left in there. Chances of it moving to a spot where it would restrict flow are pretty slim.

Re: Old Freeze Plug Inside Block

I'm kind of the same way guys. After looking at it I should be able to pop off one of the bottom plugs and have access to it. A little irritating when the machine shop either does this or leaves it in there.

Re: Old Freeze Plug Inside Block

It was a a common practice back in the sixties at a lot of mom and pop machine shops to just push the freeze plug into the water jacket before throwing the block into the hot tank. A professional engine builder knows better and would have stripped the block before sending it to the hot tank. In my opinion it is an indication of being lazy and looking for an easy out, rather than taking the time, and putting forth the effort, to do the job correctly. I certainly would expect them to do the work required to blue print an engine if they did this.

Re: Old Freeze Plug Inside Block

Any suggestions on getting the plug out when there's not much room behind it to turn it sideways and out the hole? Plug is of the deeper set variety and is now in the block as well. Thought I could turn it but no dice. Probably why it the other one was left in there in the first place.

You know you would have heard them rattle in there even if they didn't.
