Thanks again...turns out I'm pretty inexperienced doing any kind of anchoring to concrete.
I know your good to go now. Something for future. When I get ready to sink those sleeves, I roll up a little expoxy plumbers putty (at Lowe's "Fit-it-Stick"). I wrap the sleeve with a very thin layer of the putty. Then I sink the sleeve with the putty wrapped around it into the hole. Some of the putty will get forced out as the sleeve goes in, but that can be used to make a nicer seal at the concrete surface level. When you tighten the bolt into the sleeve and it expands, it pushes putty into any small voids in the concrete and those little indentations in the sleeve. Max strength comes in about 2-3 hours, but when that stuff has drier around the sleeve, that assembly ain't coming out :-). Also something to keep in mind for the future if one of your sleeves gets a little loose.
