I will say in pic 13 - the Fram with carboard end caps and then in the bottom pic - the 3 middle oil filters with cardboard end caps are surely the cheapest junk filters you can buy. I can see that one a mile away. Also uneven of pleat distance counts as a sub par& below oil filter. The same goes for your spin on fuel water sep filters.

Good eye by SB on the pleats being cut because at first I thought some it was oil that was thicken, in the pic it sure made it look that way.

Fresh with about an hour in some brackish stuff.

brad penn oil is some great stuff, just switching to it myself, how long was it run on this oil/filter ? like said before going to need a filter cutter to really tell much...are you running a oil temp gauge ?

They look like CAT fuel filters for the big diesels. What did you use for the housing?

If he has water in oil wouldn't he be able to see it on the dipstick in the form of a milkshake color. You could always do a S.O.S (spectrum oil analyst) on a oil sample. That is what we do on all of our motors. It will tell you if you have a smaller quantities of water or metals in the oil that you can not see with the necked eye.

Machined up some aluminum to make them fit. They can handle big flow without a problem and easy to inspect. Plus no metal tube in the middle. Hydraulic 10-micron filter.

Mobil 1 Oil Filters use a synthetic filter media and will not swell up with moisture like filters that use a paper media.
I think K&N also uses a synthetic media

Mobil one and K& N oil filters internally are the exact same filters - the exact same - one costs a dollar less. If your are worried about your filter media - look into system one filters.

I picked up this unit that has a solid fan club.

Still a paper media but Wix is a good filter. I like Amsoil EAO filters to. Baldwin is a good filter especially for the money compared to the wix internals.
