'82 1.6 NA rabbit pickup... engine seized

[aka.bugle]

  towed home a rabbit pickup last weekend... My son wants to restore...The previous owner said he drove it up into the field (and it ran well).
The engine is seized. there are no holes in block, has oil, timing belt OK.
We've removed the injector lines and injectors, and have squirted penetrating oil into the injector holes. I don't want to break the crank bolt so we have been rocking the car back and forth in gear trying to free up the engine. Any other tricks to free up a stuck engine? (We realize we'll probably have to pull the head and re-ring it, but I just wanted to get things unstuck before pulling to much apart)

I've seen guys poor Marvel Mystery Oil into older John Deere tractors with good luck. That would be rather liberal amounts and left to sit for a few days. However, I recently parted out an '85 Golf and ended up throwing that block away as nothing would work on it (not even oak board with sledge hammer!!). I later wished I had used some heat on the pistons and cylinder walls (with the head off).

The one on my build thread took a Big Freaken Hammer -maybe 20lbs- sledge hammer on a ripped 2x4. I used PB blaster left sit for 2 days no luck. Dried it up and got Free All and several hours later I was spinning it round round. If you are up for fun and have time maybe roll it down the hill and see if the clutch is still good.

pull the vaccum pump and get get an attachment to drive the oil pump with a drill. Maybe you can get some oil worked up trough those oil channels

well form my experience working on small engines, brake fluid works well to free up stuck engines ummm ive also used diesel fuel. my advice would be to remove the injectors and pour your liquid of choice down the injector hole, into the pre-cup, where it will drain into the cylinder, now you say the engine has oil in it and coolant in it so mu guess is just a bad case of ring set. just my 2 cents worth, im just going on small engine experience here, lol ive never had to un-seize a vw
