Re: Clocking piston rings
Doesn't make much real difference, they'll move around a bit anyways. For me, clocking is more of an issue of making the installation as easy as possible - as I usually have relieved engines. The issue is that it is difficult enough to get the rings past the relief (without popping out and getting caught on it, so I put the gaps at about 3:00 and 9:00 o'clock.
Relieved Engines: Also, if you are installing pistons in a relieved engine, pay CLOSE attention to when the rings are going into the relief area - in many cases they'll get hung up a bit. I watch them carefully and use a wooden paint stir-stick to push them back (when sticking out and catching on the edge of the relief). Last edited by Bored&Stroked; 08-21-2021 at 10:21 PM. |

Re: Clocking piston rings
On relieved blocks, if you take the time to make a ring compressor that matches the relief, from a piece of sleeve material, you will never have problems getting the rings in.
If you make the relief the same on all of your engines, you only need one compressor. |

Re: Clocking piston rings
People say it doesn't matter if you clock the rings, but I always do. If no relief I go 120 degrees apart. If there is a relief I clock above, below and opposite the relief. In other words if the relief is between 2 and 4 O'clock I put the gaps at 12, 6 and 9 O'clock.

and then about 120 deg apart. Yes they will turn some but no way to control this. |
