    Has anyone tried it? Mine looks extremely clean and relatively new, but a lot of people seem to think I should have replaced it when I did my rebuild. I can get the parts that the diagram shows for significantly cheaper that $180 for a new pump.

    I'm not terribly fond of reusing oil pumps. If it has a lot of miles, I would seriously consider replacing it. For me, that would be around 80k. We don't have enough super high mile engines to know how long they'll really last or if they're wearing and losing pressure.

    There's no inspection procedure in the engine build manual, so no real way to measure anything to see if it's still in spec or not.

    Secondly, if the engine blew up and sent debris into the oil pan, it may have gotten sucked into the oil pump. In that case, I wouldn't risk it and replace it. $180 sucks, but it's a lot cheaper that another rebuild.

    Yeah I'm wondering if it's even rebuilding again at this point

    The oil pump is literally the heart of the motor. I have not found a rebuild guide on the oil pump. Those 2 reasons alone should be enough to warrant a new OEM pump.

    You can use the ecoBoost mustang oil pump with no issues at all and it costs about $60. Just some food for thought.

    EDIT: reading fail on my part. Just realized that was mentioned above.
