A bad day, my engine is seized!!
well i started tearing down my parts truck today and decided id take a shot at starting up the old 390 that i planned on freshining up and putting in my truck.. i pulled the plugs to spray a little wd-40 in them since it has'nt ran in like 3-4 years whe i pulled the passengers rear plug i relised there was water in the cylinder. i then looked down the carb and i can see it somehow got in thru the carb and found it's way to that rear cylinder..
i heard it run about 3 years ago, she realy purred good back then.. the engine only has 59,000 origional miles on it and now it apears to be no good.. i vacumed out the water and sprayed the cylinder, but she wont crack loose.. even with a breaker bar on the crank bolt, she's stuck... so that led to a real buzz kill, now i have no engine for my truck. i had put all my marbles on this engine before i even got the parts truck home..

you have nothing to loose at this point!
grab some PB Blaster and spray the stuck cylinder, I would also pull the dist and crank the oil pump a bit to get some parts lubed up.
I wouldnt throw in the towel just yet! Work at it for a while you might get a surprise!
I bought a 1990 460 crew cab 4x4 years ago off a guy who swore the motor was stuck. He ever grabbed a socket and showed me that the crank wouldnt turn.
A little PB Blaster and a couple days of muscle later...VVVVVRRRRROOOOOMMMMM!!
The truck eneded up getting sold, but it is still running today!

Yeah, for sure don't give up. My uncle gave me an '02 ext. cab v6 that he attempted to change some sensor on the front end. Well, that's as far as he got. He left it sitting in my grandmother's yard for 6mos. with the timing chain cover off and it froze up! It is very humid down here so I assume that caused it. I invested in a borescope and sure enough when I looked in the cylinders they were rusted just right on top of the piston. I didn't want to break a ring so I called my friends grandfather who was an old drag racer. He said Marvel Mystery Oil soak and then turn it over at the flywheel because I would have more leverage. I used Aerokroil and let it sit for 3 days. I tried to turn it it at the front bolt, uh-uh.
I then used a large screwdiver on the flywheel teeth and it barely moved! I worked it back and forth and then hit the starter and it turned over. It doesn't take much corrosion to freeze up something in that tight of a tolerance. I gave that truck to a woman who needed a good ride and it still is going after 2 years and no smoke or problems. Just don't force it. Good luck.

I'm with these guys, at this point your engine is garbage, so you may as well give it a go...all you can do is make it better now. There have been a few low mile engines I've pulled out fields that 'ran when pulled'...but after a few years in a field, they tend to seize. I usually use a concoction of PB and tranny fluid down the cylinders. Let it sit a few hours, work the crank back and forth...and do this every so often until it breaks loose. I had an engine I did this to at least 10 times a day for a week before it broke loose. As soon as it did, I threw it in a Bronco...drove it for 5 years and sold it. Only thing to be careful of is...use a little finesse or you'll surely screw up the rings.

yea! go for it. i have a 46 f-6 with a flathead in it 3 of the 8 cylenders were stuck i took the pugs out and POURED marvel mystery oil in the cylenders and left it for several months came back and bumped it with the breaker bar and it spun. the marvel mystery oil is probably no better than pb blaster ( i like them both) but i think the mystery oil tends to "leech" and "crawl" better it will climb around in the cylender u may have a good chance with it. if nothing else you could tear it down and hone it out. good luck!!

you all have good pionts to get across... i'll try at it a bit harder today and see what i can do. if i cant get it un-stuck i have a freind who has a 1974 lincoln 460 and c6 tranny sitting in his garage with 46,000 miles on it, real clean and he only pulled it a month ago.. he told me 400.00 for it, so i can go that rout if i have to..

just remember when trying to "break" it loose not to actualy break it, althought i dought you'd harm it with a 14 inch breaking bar. gental back and fourth preshure is far better than lots of preshure one direction. you can shear wrist pins and conecting rods this way

I know a guy that actually grabs any engine he can, and often gets those that have been sitting in a field and seized up for years. He pours some Marvel Mystery Oil in each cylinder, lets it set for a while, and they always break loose for him.
You could also try this (quoted from various places on the internet):
I've yet to try it, but it's pretty interesting info.

Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts. They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment. The results are as follows;
Penetrating oil..... Average load
None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ............. 214 pounds
Liquid Wrench ..... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix....53 pounds
The ATF-Acetone mix was a "home brew" mix of 50-50 automatic transmission fluid and acetone.

just had a brainstorm depending on your valve position you could put the penitrant of your choice in the cylender and preshureize the chamber with air and push the oil down into the rings where its seized up. but! odds are the engine didnt stop with that cylender on its compression stroke.
