Fram PH8316 cut open - actually not too bad

[ThirdeYe]

The filter had just a hair under 2k on it, and over 3 months. I changed it early because we bought the car used and the maintenance history is unknown. I also noticed some paint flaking from a poor valve cover paint job into the oil filler hole, so I was worried about that as well. Anyways, the filter I cut open actually didn't seem too bad. Instead of the ADBV sealing against the cardboard, it sealed against the metal bypass insert in the tube. There was another bypass on the dome. No problems with the ADBV, instant oil pressure every time. I actually wouldn't mind using one of these again, if the price was right. The pleats weren't bent out of shape/distorted and the endcaps were still uniform.

I apologize for the poor quality of the pics, my battery died on my regular camera so I used my cell phone instead. There was a hole in one of the cardboard endcaps but that was from me piercing the ADBV with a nail and it accidentally went through one of the endcaps.

Note, this was from a 1998 Ford Escort ZX2 with about 92k miles on it at the time of oil change. The oil used in this interval was bulk 5w30 Quaker State. I replaced it with 4.5 quarts of ProLine 5W-20 and a Purolator Classic L25230 oil filter. And off-topic, it's weird not being able to pre-fill the oil filter because of the unique bypass that the Purolator had!

But I thought that FRAM was sooooo bad to use....

Also one more thing to note, this can is VERY thick. It took almost 2 Dremel cutting wheels to cut it open!

Huh? Explain, please.

The 8316 style filter has a unique (to me at least, I haven't seen one before) bypass that blocks the center hole. I removed it in one of the pictures. It contains a spring-loaded bypass that can open and allow the oil to flow out through the center tube. Because of this, I can't add oil to the center of the tube as it will just sit in the little bypass mechanism. Here is what I mean:


See how the bypass blocks the center tube?

That actually looks like a outlet ADBV that I have seen on another filter here recently. Did it still have a clicker bypass at the done end?

If Fram really has gone to a thread end bypass and is putting a reasonable amount of media in their filters now, maybe I should give them another chance. If they have improved the PH 3950, it could be better than the current L 10193.

I'm not sure if the dome end bypass is called a clicker or not. It looked like the same style as the thread end bypass, with the little spring and the 4 prongs. I don't think Fram is incorporating this type of bypass feature on every one of their filters though, just some Ford applications (this cross references to a FL-400S). I was mostly impressed with the way the ADBV didn't just seat against the cardboard like the PH3506 I cut open a few months ago.

First time ive seen that - a bypass like adbv in combo with the nitrile adbv. At first I though the factory assembled the filter upside down in the can!
