[QUOTE="oexing, post: 131640, member: 1493"] Oilite bushes in this place, with dedicated oil supply into cam spindles??? That type of bushes is meant to be in places without real lubrication I´d think. So my guess when decent bronze bushes (phosphor bronze in your country? ) don´t seem to be suitable there must be a real problem with oil distribution in there. You´d have to think hard about reworking any oil grooves in there to supply all bushes plus to get all oil out onto cams and followers via holes in cams right at the start of lobes. Just drilling cam holes in fitted bushes will not do, some more grooves will be required, and you´d have to make sure oil will not be shut off when bushes may walk in cams. Do not hope for cam lubrication from the hole in the follower from any oil running down from the pushrods, not very positive as you can see in photos above, typically f***up Vincent cams and followers. It is mostly wishful thinking for some oil reaching there from flying pushrods, I´d imagine most oil from rocker supply will run down the pushrod shrouds, never getting onto followers. So I welded follower holes shut for keeping the oil wedge intact and improve oil supply via cam spindle routing instead. Vic [/QUOTE]
