Ok, hoping at least one of you has ever installed Diamond brand piston rings in a 1980 G180 and can answer a question for me.
The oil ring is pretty self explanatory.
But the upper two rings are confusing me. The original ones are both solid shiny metal. The new ones look like a black ceramic of some sort. And one set has a metal ring formed into the outside edge.
So, my question - which ring goes in the top groove? The one with the metal edge or the one without?
Thanks in advance
