Oil Filter Differences (6.0L) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I did a search and cam up zip, zilch... na-da.

2006 Chevy 2500HD with the 6.0L Engine. Looking at oil filters for when I change the oil. There is an AC-Delco PF-46E on the 6.0L right now. Was on there when I bought it at the dealer last month. So I was at my local parts counter (which is a mom and pop store with good knowledgeable people backed by Parts Plus), and asked them for an AC-Delco filter for my truck. She comes back with a PF-61E. Says that's all that the computer lists. I tells her that the truck has a PF-46E on it. Now the gals that work at this place know their stuff... so she was stumped as to why the PF-46E was not showing up for the truck, and only the PF-61E was.

Looks like the PF-61E will fit my truck. It is a smidge longer than the PF-46E. But after she and I did a little research it appears that the PF-61E has no "anti-drainback valve" in it where the PF-46E does. Soooo...

What the heck? What is this "anti-drainback valve" monkey motion, and does the 6.0L have this feature? My oil isn't due to be changed in a bit... so if I have to order a PF-46E I can. No biggee... but I like to support my local businesses when I can. Been going to this parts store for 20+ years.

Anybody got any info to share?

the anti drain back valve is designed to keep oil in the filter when the engine is shut off. however, since chevy runs the filter in a position where the fill hole is on the top the drain back valve really serves no purpose. you can run either filter just make sure the threads are exactly the same and the diameter of the o-ring is the same.
