Hi Anibal
First is a geometric rule
2 are set at 120 degrees so that it is not as rigid as the piston tends to "nod when you put them at 120 you get the rings to be damped in the pitching thing that does not happen at 180 In addition to because it improves the lubrication and cooling of the hoops Of course, behind this technicality there are techniques and trials especially in modern engines, but not in old generation engines in old engines, you put the rings in one way and often they turned on their own but it was another material and different piston different rules

thank you friend for your valuable time and comment
I ask you an additional question
I am putting together a zetec rocam 1.6 party engine, I have a great doubt that the crank shells that that car brings are smooth and they sold me some with holes, this could bring me oil leakage problem or not

I think you mean connecting rod metals?
It wouldn't be a problem you can put it together if

The rings we ask to place as we want or as we think we know but there are rules of why already 120 degrees is the best

Why do we pin the hoops at 180 degrees? It is easy because we face an opening with the other because we do not put it as they should go (as manufacturers advise us) because it makes it difficult for us or we do not want to take the time to look for 120 degrees
