Hi any one know the part number for 2010 4L timing chain tensioner washers from Ford? Thanks

 

I think it was XU2Z-6M252-AA

But not sure if they still use them

 

When I change my tensioners, one had the washer and one did not and is the way they were installed at the factory. I don't know if it was a mistake or on purpose. I don't remember which one had the washer but I installed them as they were. I did put a little sealant on the one that had no washer.
