The picture above showing the lines is overkill.


There are better and easier ways to provide a good oil flow to the rockers:


There are special bearings that have a groove in the backside so no matter where the bearing is you get oil


Another way is to groove the block behind the bearing so no matter where the bearing is you get oil. This method is used by a well known YBlock engine builder


As was stated above, poor maintenance and terrible oil conrtibuted to most of the oiling problems Y's had.
