2023 Fram TG7317 light leak.

[pcf]

Smooth spring Fram filter with a lousy seal. Just stiring the pot, cuz the handwringing over the new springs is funny.

I cut open a used gold can the other day and it was fine. No wavy metal on the bypass bracket

Oh boy ... another leaker. "But it will catch the stuff that goes by the media on some other trip through". <"justification">

Put some pressure on the spring and test again.

This leaf spring must have some warp to it. Got a photo of the impression left by the leaf spring in the fiber end cap?

It's a relatively old build, made the 187th day of 2023.

I did. I’m not smart enough to figure out how to photograph it but it was about the same.

Edit: wait a second, I’m fat, this gut has more than one use.

Certainly different than this TG10575 …

Methinks oil might have played a significant role in that.

Heat, pressure, etc …

Looks like no contact in the red circled area.

That’s with a little graphite and spinning it 360 degrees. The spring appears flat. Running a straight edge across fiber, it’s flat. It’s the opposite of what it appears, the circled area has a deeper indentation.

Does it sit flat regardless of the rotational position of the leaf spring on the end cap? If the leaf spring is not put back in the same exact rotational orientation as it was before the filter was cut open, then it may show a leak gap. The fiber end cap depressed more on the ends where the ears are on the leaf spring.

Deleted. More research required

It's great that some people will still buy all these leaky oil filters to help keep those companies in business.
