Engine problem

[The Godfather]

Hello,

I have a problem: Just bought a used engine (2000 VW Golf 2.0L AEG)

I went to the place to check it out, did all kinds of tests to it (most importantly, I manually spun the crankshaft so I can see how the compression is and whether everything is in tact). I spun it a couple of times to be sure.

I came home, put the motor on the engine stand, and now when I try to spin the crank shaft, it spins halfway and it stops at one point. Something is preventing it from spinning, but I have no idea what.

The camshaft is fine, and so is everything else (they spin properly)..

Any ideas what could be preventing the crankshaft from spinning?

Thanks.

pull the plugs and have a look in the chambers. If it really did spin before you bought it, its VERY unlikely (impossible, I think) for the time to jump enough to cause rotational issues.

secondly, make sure all the rotating parts outside the engine are clear, and that nothing is keeping the crank from turning there.

Flywheel isn't caught up on the engine stand or anything like that? If it turned 720 degrees before, there is no way that wouldn't turn now unless you didn't get the same engine you saw before.

You say the camshaft spins fine. That leads me to
think you had the belt off. Could the timing be wrong
causing a piston to hit a valve? Also, what happens if you
spin it the opposite direction?
