What I see in the picture is that the oil gallery coming up to the valve train has been restricted. Typically they tap that hole. Then bore a hole through a plug, and screw the plug in. Your block appears to have a pressed in restrictor. It is fine that it is recessed.
There are four of these oil holes. Notice the water jacket to the right of the head bolt. Put a straight edge from the oil hole to the water jacket and make sure the deck is flat. Also look for a crack in the block between the head bolt and the water jacket. The deck can be crack free and the crack be down in the hole. I would try pressurizing the head bolt whole with a compressed air rubber tipped nozzle. |
Yea, I guess sleeve was a bad term to use. Restrictor makes more sense. I'll try pressurizing it when I take it apart. I read on that thread you posted that a certain loctite on the head bolts can temporarily fix a crack in the head bolt holes, I might do that in the meantime.
