I found the specs for the 8n ring end gap for the top 2 rings but I don't see the end gap for the lower oil ring. I bought an 8n that was smoking pretty bad. It had good compression. Pulled the head and oil pan and found the cooling passages in the head COMPLETLY filled with mud. The cyl. looks good and measures standard and within specs. The engine appears to have been apart recently. Looked at the rings and they do not appear to be worn, but the top 2 have an end gap over .070 and the oil ring gap is over a 1/4 inch. I am thinking that someone put in the wrong rings. What is the end gap supposed to be on the oil ring? Thanks
