What is your question?
car died while driving. made rattling sound. checked timing belt which was replaced less than 2 yrs ago. Tried to line up timing marks with socket & breaker bar. Motor would hang up and wouldn't move. Had to move back & forth to get it to move again. It would hang up at the point where the timing marks were aligned. No compression on 2&4 cyl. 1&3 are normal. Removed valve cover and saw no obvious problem. Pistons are moving. Help!

This engine is known to break connecting rods. Remove spar plugs and look down in cylinder. Watch to see if and how much each piston moves. You should see one moving very little or not at all. You may also see a spark plug with electrode closed from piston slap
Thanks. The pistons seem to be moving all right. I stuck a small wire into the spark plug holes one at a time and the movement seemed to be the same. Removed rocker arms from the affected cylinders and still had no compression. Ready for the junk yard I guess. Car not worth much anyway.
