    Can anybody tell me the correct location and angles for drilling oil holes in the 4.4 block to supply oil to 3.5 rockers

    Hi Rangieman,

    A mate did the same thing on his previous rangy but said that it gave him some dry rockers.

    I suppose it could've been another cause like blocked pushrods/rockers or cam followers.

    I'll put it together and see how it goes over a period of time.

    Thanks again.

    My 4.4 has 3.5 heads, the rockers are lubricated by an external oil line coming from the oil pressure switch location on the oil pump, going behind the block and through a bulkhead fitting into the valley area, where a T piece
    takes a line to each rocker shaft, haven't seen the internal bits as I have never had the rocker covers off, but engine builder said it was necessary.
