    I think those are a weep hole for the liner seals. Bet there's 6 of them along the block.

    Ok. I assume coolant isn’t supposed to come out of there?

    No it should not. Hopefully your lower block is not eat up and that is the reason the o-rings are not sealing good. The shop that is doing your overhaul needs to take a really good look at your block.

    Yeah, I plan on doing everything I can and reading up(been doing it) on everything I can get done.

    Problem just started recently in the past 2 weeks. I noticed I had to add coolant. Not much but just enough....... Gonna start tearing it down next Friday(Not me, my mechanic):D

    I wonder if anyone makes a “crevice seal” liner for a Detroit. IDP makes them for Caterpillars. Basically it’s a crutch for questionable lower counterbores.

    Just make sure he has the tools or can get someone to do a proper check and counter bore before you let him start tearing down.
