hey all, new to forum and am re-building a perkins 3.152. I am having difficulties properly orienting the piston rings top up. I have a set of Vapormatic # VPB4000 rings that clearly say they are to be oriented up but upon inspection I cannot see a clear profile or angled edge or any stamping on any of the rings that indicate the top. Can't proceed without some kind of comfort level with this.....any suggestions would be greatly appreciated

I now know how all the rings are oriented except # four(4). It's a multi layer ring set with one (1) expanding. I believe to be a oil control. Once again, you tube wasn't very helpful Does anyone know where I can find a diagram showing proper ring installation? My only other choice is going to a machine shop an seeing if they can help..... Thanks
