Ring end gap clearance has to be checked and verified or severe engine damage can result. The following are general recommendations. Consult the manufacturer's instructions and use that if they vary from these recommendations.

+
End gap placement lets the engine start up without any gaps being aligned. Once the engine is in use, the ring end gaps change, this gives the best chance of them not aligning during use.

The ring end gaps need to be located in such a way that they don't align. The rings tend to rotate on their own during the life of the engine, so starting them out as shown will prevent them from aligning, at least not right away.

The idea behind staggering the ring end gaps in a certain way is to have the engine start up without any gaps being aligned. The rings tend to rotate on their own during the life of the engine, so starting them out as shown will prevent them from aligning, at least not right away.
  
 
While there are different thoughts on ring end gap placement, unless the manufacturer's instructions say otherwise, the following diagram will work fine:
