May Day !! Down a cylinder

What does the intake port look like on that cylinder. It could be a small crack or sand pit in the head casting allowing oil to be pulled in to that cylinder. You could do a vacuum check on that port if your machine shop has that type of equipment. You could have a problem with the oil ring in that hole too. It will leak check good even if the oil ring is not sealed. The expander could be lapped over.
