Assuming nothing is worn out or has failed, you are missing something. The most common thing people forget is two wrist pin clips in each piston for a total of 8. There are other potential causes:
*Missing thrust bearings (needs 2)
*A missing bearing anywhere else in the engine (16 crank/main cap bearings, 16 rod cap bearings)
*Missing piston rings
*Missing rod nuts

There are probably more things but I think those are the most common.
