My issue is when I search for thT part number I’m seeing them with both the old design and new design. So I’m only considering items where they show the underside of the valve cover so that I can be sure it’s the new design
Probably sellers posting generic stock photos. When I need to be specific, I'll contact the seller and have them personally check an item if not send me pictures of the actual item they'd be shipping to me.
If they wanna be too lazy to post actual pics, then they deserve to be hassled.
...For you ebay sellers on here, that last comment isn't directed towards those that buy merch in bulk to resell and never really know anything about it. It's towards the online car parts stores that should be more careful.
BTW, I'm sure you've already figured it out, but you can ignore the part number that's embossed on the underside of the valve cover. That's just for the casting of the cover which is the same across all the center bolt style covers, regardless of the PCV baffle or orifice version. Actually, that may be why some of these pics in the ads for the updated covers are of the older design.
