Hi there , I've got my crank back after a regrind. I've noticed on the big four end journals there is three oil holes , the one in line with the web is bunged. I'm thinking this is where the factory drilled the oil gallery in the webs then capped them off and is correct as it should be. Before I reassemble the engine I thought I better get a few thoughts from those who know cheers David.

I'd say a picture would be quite appropriate...

That is correct, the drillings were drilled & bunged in the cross drilled S cranks.

Many thanks mark ,second opinions are most helpful , I lost oil pressure hence the engine rebuild.im an avid watcher on the forum and all going well the engine will be back in and few local miles done in time for the action day (travelling down from Ayrshire) .david

Good luck david, I look forward to seeing you there.

On old cranks it is quite common for these holes to block solid which means no oil feed to big end

We always take them out now to fully clean out holes and turn up new plugs .
