    I'm pretty sure the date of manufacture isn't encoded in the VIN, but the year and month are printed on the manufacturer's sticker on the trailing edge of the driver's door. (It's the one with the VIN, GVWR/GAWR, and compliance statement.)

     

    You're right, there is a date there on my vehicle. Good info - thanks!

    Is there any way to determine for any particular vehicle whether it was built with the newer engine type with the modified relief design, or the older style engine? Perhaps based on the VIN# of the vehicle in question?

     

    Let me try asking the question a different way... Is it possible to determine whether a particular model year of vehicle, or a particular VIN was build with a short block engine (which I understand should have the updated relief design)?

    In the course of visiting the dealership, I've started considering the possibility of an upgrade. Of course, what I wouldn't want is to discover that the new vehicle has the same issue, and in the worst case, it is potentially only discovered after the warranty expires...

    Porosity is NOT the issue. Core shift due to the stress relief cuts between the cylinders are. The cuts make it so the fire ring cannot seal properly if there is even a little shift. The new short blocks have cross drilled reliefs rather than cut. Not sure when production moved to these.  

    As of now, the 1.5 is being repaired with short blocks unless the plugs bind in the holes from the coolant. They don't even want tear down on those now. The 2.0 and 1.6 are long block for intrusion only.  FYI: 1.6 has always been 6006 since launch.

    Looks like I'm late to the discussion, so I'm not sure if anyone is still monitoring this thread... This is excellent information, just what I needed. Thank you @YT90SCfor posting it.

     

    My low mileage 2017 Fusion (1.5L engine) is currently in the shop to replace the engine due to the 'coolant intrusion' issue. The service advisor states that a 2017 short block, DS7Z*6009*G will be the replacement engine. I'm not completely clear whether all short block 1.5L engines would have the the cross drilled reliefs? (I wasn't clear whether 'when production moved to those' meant new car production, or new engine production - sorry if I'm being dense.)

     

    Can anyone confirm (or tell me how I can confirm) whether a 2017 1.5L engine with the part number above should have the improved (cross drilled) reliefs?
