Am I going to have to completely rebuild the thing? What steps needs to be taken? (btw, right now, everything is off.. tranny, clutch, pressure plate, flywheel, bellhousing) - I'll be mounting it on a stand tomorrow.. what all do I need to do? Much thanks!!!

Are you able to get any movement at all, or have you tried? Once it's on the stand, reattach the flywheel so you'll have something to pry on, and remove the cytlinder head. Scrape out any serious rust deposits above the pistons, then soak the cylinders with some type of penetrating oil such sa Diesel fuel, Marvel Mystery oil, Kroil, Liquid Wrench, or PB Blaster. WD-40 is a poor excuse for penetrating oil, so use it only if nothing else is available. After a few days of soaking, a pry bar on the flywheel teeth might allow you to move the engine a little. Keep working it until you can see where the pistons were stopped originally. If there are deep pits, it's time for a rebore or even sleeves. If the pits are very shallow, they can be honed out.
If soaking and prying won't break it loose, count on a total rebuild, or possibly scrap it and find another engine.

how did you manage to get the clutch pressure plate off with a stuck engine? | | |

truckernix, I don't think its totally locked because I was able use a big screwdriver to help turn the flywheel (while I was removing the pressure plate and clutch) - I mean, it turned VERY VERY slow and took about an hour to turn it to get all of the bolts off... since it moves a little, should I not really have to worry about anything?

Diesel fuel will be the least expensive, and it's pretty good for freeing up tight engines.

I rocked mine a few degrees until eventually it would turn over. It took several days of soaking. My intention was to test run it and listen for bearing knocks before I took it apart. It didn't knock but it burned oil from some stuck rings. When I tore it down I found that the rod babbitt had dropouts from antifreeze getting in the oil through a blown head gasket.

Soaked it, pulled the head.
It freed up.
Put it all back together.
Took it apart again.
Reseated the valves.
Put 'er back together.
Drove it for 6 months even though all the lower end seals were gone and she leaked like crazy.
Open her up and see what ya got.
Good Luck. | | |
