    How the **** do you remove OLD core plugs?

    Trying to remove core plugs from my block, i don't know the age of the block but i'm guessing 20 years.

    The core plugs are propely stuck in. Old sealeant and rust. I've drilled a 6mm hole in each one, hoping to just be able to flick them out with a screwdriver or something. Yeah, that worked NOT!

    I elongated the holes in one of the plugs, enough to get a pry bar in there, and then a heel par. Neither of which even make the plug budge at all.

    I've now retired to the house for a brew, after soaking all the plugs in plus gas. Anyone have any ideas? I know Ffoeg must have some sort of clue

    Chap the screwdriver down the side of the plug, between it and the block then just pry it out.

    Never had a problem getting any out this way.

    between the block and the plug seal? Try to fold it in, sort of?

    Don't hammer anything down the side of the plug - you'll score the block and changes are it'll leak when you refit.

    Get an old flat blade screwdriver (larger the better), grind a sharpish edge on it, and whack it straight through the plug, slightly off centre. Once through, lever the plug round, so you can grab the edge with mole grip and then just pull/waggle it out

    That's what i was trying to do with the pry bars and the heel bar. No luck yet, i'll have another look in a bit

    Nargh .. anything to give them a bit of room to deform across the middle will help no end - be it drill hole, screwdriver puncture or punch dent.

    just give the block a good flushing when you've done to get all the crud out.. which I assume you'll be doing anyway
