So I'm assembling my new motor and I was just gapping my rings... First and second are good to go, then I get to the oil rings.... ? They are all too big. Like, I would have to cut the oil control ring just to get it in the block to check the gap.... I'm talking like, 1/8 inch excess on the control ring that needs to be cut off. As for the upper and lower control rings, they have literally no gap at all.... Did the oil rings from another set get mixed up with mine? Anyone else have this experience? The two top rings were actually all within spec right out of the box. The oil rings just have me wondering what happened. This is the second set of NPR rings I've rebuilt a motor with and they were not like this.
