[QUOTE="greg brillus, post: 96756, member: 597"] The holes in the case back into the vertical holes for the threaded cylinder hold down studs, and these have a machined groove around the mid section of the stud to allow the oil to pass around the stud and on to the cylinder liner feeds inboard of there. The are lots of opinions about the use of them or blank them off. I am of the thought that the oil being thrown off the bigend and upward to lubricate the piston skirt and the gudgeon area is a bit limited due to the long stroke design of the engine, so I feel they should be used. The main thing to watch is that the oil holes in the liners are injecting oil bellow the lowest piston ring. A lot of factory liners left with the holes too high, thus injecting oil into the rings and causing oil usage. If this is done correctly, then it should cause no problem. [/QUOTE]
