Mazda fc 13b turbo split oil feed for turbo on frunt iron I no the best way would be to take the long rebuild route .... but the motor was freshly built last year and don't fance striping down a built motor with less than5 hours drive time on it ...but my question is is there a way to block the frunt iron oil gallery from down on the side of the motor or are there outher bearing feeds in that galery stem ??
