crankshaft problem....or not?

Okay so today I was greasing up the pistons and walls wile the head is off so i dont get any surface rust, well I thought I would grab a socket and turn the crank slowly, i noticed it would only go about a turn and stop, then a turn the oposite direction and stop, i proboly could have turned it with some force but didnt want to mess anything up, other than that the pistons go up and down good for that first crank. Is this normal? Also i have a 6 bolt 92 eclipse gst.

Uh, it's not possible to put the crankshaft in backwards. The flywheel end is huge - it won't fit into the front main.
