    I have a 13 Explorer sport that has started a leak at or around the oil pressure relief valve. The dealership replaced the faulty one but I still see a leak that drips onto the oil filter, but never on the garage floor. Seems like it only leaks when the truck is on, and probably when the oil gets hot?

    They have seen it twice but the second time they drove it around but couldn't replicate the issue. On the way home from the dealership, I looked underneath and sure enough oil had found its way to the bottom of the filter.
    It doesn't appear to be a bad leak, as the level is still close to full, but just aggravating.

    Anyone else with an Ecoboost have a leak at or around the filter/OPRV? Dunno if it's there or higher up, as the space in that area is tight.

    And fwiw, truck is under warranty. Guess it goes back in again...

    Pics for reference.
