Could be a head gasket as well. Maybe you already have, but I'd rule that out before s****ping the block.

Sorry, but bubbles in the radiator are a sign of cylinder pressure getting into the cooling system. If it's not a blown head gasket, it will be either a cracked head or cracked block. I don't know of any sealer that will hold up to cylinder pressure.

I would try Moroso's Ceramic Engine Block Sealer, they make two different kind's, one for antifreeze and one for without.

I used it and it works good, a late model friend said he put it in when he left for the track, started the motor up and let it idle on the trailer while he was pulling it.
Stopped part way shut it off, then ran the last half of the season, it fixed a good crack in his head.

I've got a 3" crack about 1" below the deck and 3" long it sealed up. Been running the whole season this way.

I'd like to smell that trailer when it was opened up...
