Man want to drain n get sand n debris out of block. Holy crap they don't want to come. Any secrets . They are brass with pipe dope on them and are there to stay.

Maybe a little heat?

That's what I was thinking too !

Ayuh,.... Use a wrench or socket,....

They should never be installed that tight,....

Just abit more than finger tight is plenty tight enough,...

Put some muscle in it you p*ss*!

6 point socket and eat your wheaties.and not the catylin jenner kind.

I have seen idiots use furnace pipe dope/sealant,,only thing to break it is heat.is the dope brownish by chance?

3/4 inch impact and a socket

Are you talking about your core plugs?
There's space behind them. Drill a hole and put in a tapping screw, grab it with a pair of side cutters (formerly known as dikes) and lift against a piece of metal as perch for a lever.
Or slide hammer while heating the edges.

I feel kinda dumb now, I installed my plugs with thread sealant.

If it's the block drains, I'm out. The guys who answered have it.

Try hitting them with a hammer, this will definitely help. I have had to do this a few times. After hitting them most of the time they will break loose.
