motor ruined?

79, 12a carbed factory motor 105,000 , so im driving home tonight, and my low oil light is on, i cut the car off and coast into a parking lot, see smoke pouring out of my hood, pop the hood to see that the lower oil cooler line is off the block, and my car wont crank over at all, when i try to turn it over it just hesitates, like the motors seised, any tips here guys? its currently my olny car and i need a car by monday

Sounds like she's cooked herself
If you need wheels by monday, you'd better start with the newspaper ads, etc. The SA isn't going anywhere w/o a miracle and/or a rebuild....

sorry man-

Lots of great advise here if you want to resurrect her. You didn't mention any over heating so IF you dodged that bullet, and didn't seize it maybe hooking back up the line, topping up the oil again, she'll restart? If the rotors have truly seized it might have to be pulled apart and resealed, assuming no damage to housings. Lots of unknowns here, but have heard of some amazing resurrections so maybe someone has an adventurous idea??

the car defentily did not overheat, i was watching the temp gauge the entire time, but the car will just not turn over, when i crank it the fan moves, but being in the car i cant see if the belts just slipping on the crank pulley, i can just see the fan moving an half inch or so each time i turn it over, i want to crank the block over by hand but i cant get a ******* rachet combo in there past that fan

Really if it is not locked (guessing no if the fan is moving while cranking) you should be able to turn it by hand using the belts and lowest pulley... Good luck man, hope she survived.

I would also say a rebuild is in order, but for our morbid curiosity's sake, throw a socket on the front pulley, pour a little oil in the carb bores(take the plugs out too), and rock it back and forth.

Even if locked up, they're sometimes recoverable without horrific expenditure depending on what failed; you'll still likely be looking at a rebuild, but if you (for example) spun and jammed a main bearing, that 's not nearly as costly to fix as having blown and chopped a rotor seal.

However it turns out, good luck.

well mmo was placed in the motor the night it happend (thursday night) and i finnaly got to pulling the radiator, so i could get a socket on the crank pully past that fan since i cant figure out a way to hold it to unbolt it, and the block is spinning, theres resistance still but ive been working it, now waiting, gonna go work it more, when i go to start it it spun for a second and my battery died. all this was with plugs out. so at this point im gonna continue working it untill my batterys charged and attempt a start, and if nothing happens ill pull the block and pull it apart. any suggestions?

It is gonna smoke like a bitch once started, so be ready for a quick trip on the highway. If it starts, take a good long hard drive on the highway and cross your fingers!!!
