sorry for the delay .. ok on this when the head is being machined before installation on the block they have to drill a channel for oil passages . and after they machine it they need to seal the end of it so no leakage gets by so they insert a ball bearing (bb) and peen the end to seal it . i have seen from time to time that they tend to seep and with oil pressure tends to widen the peen and then start to leak . the rectification is to replace the cylinder head . i have seen macinists take the bb out and place a pipe plug in place but the cost effectiveness and turn around time is better if the head was replaced than repaired because the chance of leaking again!!
