Thanks in advance,

Only from what I've seen people post in that oil pump thread, plus other places online. Most of the pump failures are from build dates in July and October, but there were some outliers as far back as April and through early November, all with the same exact issue - a cracked/shattered oil pump gear housing.
What would be really informative is to know the part number of these bad pumps, but I don't think that's going to be easy info to come by. I just know that Melling has revised the part around 5 or 6 times.
