Using a pump for a parts washer, run the outlet to the valve cover (alternating covers on V engines) Put the pickup in a drain pan below the removed drain plug. Pump kerosene or diesel fuel through the engine for however long floats your boat (engine not running) Let it drain over night and fill with Super Tech, crank with ignition disabled until pressure comes up, run for a short trip and change.
Never done this, just an idea. I like that engine isn't run without anti wear additives.
