I recently changed the oil on my 2011 Frontier. I used a new style PH7317 filter. I started the truck after it had been setting for 2 days and heard an obvious start up rattle. I let the truck set for another 2 days and got the same start up rattle when the truck was started. This was not a problem when the truck was restarted several times on the same day. I had another PH7317 on the shelf so I installed it. After letting the truck set for another 2 days with the replacement filter, no start up rattle when the truck was started.
 
I can’t say I’ve ever had an ADBV failure, but they’re bound to happen.

Come to think of it, all my filters have been vertically mounted so even if an ADBV did fail, I probably wouldn’t have gotten any symptoms.
 
It's just a one in a billion chance on the first one. Maybe it was the oil or wheel bearings, maybe the tires :oops:.
