CRACKED Engine Block?

I just changed the oil in my 82 w150 slant 6 2bbl that i replaced the head gasket on. Now i drove it, then i opened the oil cap, and there is still white milky stuff appearing. Also the coolant was a little low. i see a little is leaking down the side of the block, but it is leaking from this groove, that looks to be cracked you be the judge. How do i fix this. Replace? I have a engine in a 78 D100 parts truck. its a 2bbl. i just took the carb off of it and its on the cracked motor. the current plan is for me to unbolt it, and then we will have a local shop, or the guy we bought the 78 from rebuild it. how much should a rebuild cost?

looks like a small crack. you can got to autozone and get the sealer stuff - it may work - i had a crack in a cylinder head of a 2.3 ford mustang and put this stuff in and it held for over a year (and 15,000 miles).

Th key ingrediant that you need to look for in the sealing stuff is called "water glass" or also known as sodium silicate. The key to making it work is to drain the coolant and flush out any antifreeze in the block. Put this stuff in with fresh water and run the piss out of the engine (get it hot). The drections say to run it atleast 15 to 20 minutes after operating temps, then drain the system competely and let it air dry for 12-15 hours. Since my crack was to the combustion chamber, i just put thestuff in with plain water and drove it a week. then drained the system and put back in the antifreeze. it held for over a year and alot of miles. This could buy you time to get your other motor done nicely.

As for the rebuild - depending upon what is needed - 300 to 1000 bucks should cover it.
