Message: [QUOTE="Johnboy3, post: 249268, member: 708"] Figured I post this up since we have been getting more and more trucks in with the wrong oil filters installed. For those that don't know, Napa/Wix makes a replacement filter that has it's own cap. It is taller than the factory Ford cap. The filter that comes in the taller Napa cap is glued in and can't be replaced with a cartidge. You throw the whole thing away when changing the filter and replace it. Notice the difference in caps: [IMG]http://www.littlepowershop.com/publishImages/60_Oil_Filters~~element26.jpg[/IMG] Also notice the big DO NOT REUSE words on the taller Napa cap. For some reason folks miss that and pry the old filter out which is glued in there. You can tell if you are trying to put the wrong filter in the wrong cap because the cartridge filters have little snaps on the top that click into the cap. If it doesn't click, it isn't the right combo. Here is a picture of Fram cartidge vs Napa/Wix vs Motorcraft: [IMG]http://www.littlepowershop.com/publishImages/60_Oil_Filters~~element27.jpg[/IMG] Notice how much taller the Napa/Wix filter is? The reason this is a huge issue is that there is a drain in the bottom of the oil filter housing. If you use the tall cap with the short cartridge, it will not close the drain and the oil will bypass back into the pan. Which does not provide enough lubrication for your engine. Which gives you the opportunity to rebuild or replace your engine like the poor soul's truck that we removed a mismatched filter and cap from today. After seeing this yet again today I figured there must be a new wave of 6.0 owners who aren't aware of this issue. I have also had a rash of people on the phone who, "just changed the oil and now it doesn't have oil pressure when it warms up." I'm also not a huge fan of the Napa/Wix filter with the taller cap period. Eliminate all possible problems in this area and just use the factory cap with the cartridge filter. [/QUOTE]
