If you're getting lifter rattling on start-up, or the oil pressure gauge takes longer to show full pressure, those could be signs that the filter is draining overnight and the lubrication system has to refill everything in the first few seconds of the engine starting. It doesn't take a defective ADBV for that to happen, just a cheap or poorly designed one, something that's not uncommon. Simple fix: Just try a different brand of filter. Silicone rubber ADBVs (often red in color) typically perform better and last longer than standard rubber valves (often black).
