1967 camaro 383 engine took a huge dump on me at the wrong time not that there ever is a good time, anyways the anti freeze/water is coming out the tail pipes when driving, after putting a pressure test at the radiator the water was going some where with the car off, i couldnt figure it out as i already had pulled the intake manifold and replaced its gasket, anyways i keep hoping its would be at worse a blown head gasket.

Now what is bothering me is i pulled each plug 1 by 1 of course all were dry except when i pulled the last one as this is such a great day right, all my anti freeze came pouing out onto the garage floor.

Thus im not certain this can only be a blown head gasket as i have antifreeze in the oil pan and now in the cylinder? the heads are aluminum is it possible that both the water and the anti freeze could seep down into that one cylinder? i have always thought if you had a blown head gasket the water etc would stay at the top half of the engine its all messed up and now needs to be towed to a shop and i just dont know if its cost effective to rebuild it or look for yet another crate engine..

 

It could be a cracked or warped head, that's what it sounds like to me. The engine may be salavageable if you did not drive it to long with the leak, you may just get off with a new set of heads as long as you did not do any bottom end damage to the berings.

 

Another possibility you need to prepare yourself for is a cracked or chunked out cylinder wall. Due to possible core shifts, not all cylinder wall thicknesses are perfect all the way around. And an overbore, like the .030 your block got, can create a dangerously thin spot on one side. Let's hope that's not what happened, as that would turn your block into scrap.
