Jim TN, yes it's good to clean those oil holes to the water pumps BUT, there is no oil pressure in those holes, they just go to a cavity in there and the cam gear throughs oil into that cavity and it just runs down into the water pump hole to feed the early pumps with the bushing. The 8BA pumps have sealed bearings and don't need that oil hole. Walt
