This spin-on oil filter adapter thing
As a new proud owner of his first Porsche 911, I've gotten a 996 and am doing the maintenance myself. I found some grit in my oil filter after the IMS bearing was in bad shape 13k km ago - debris from this still resided in the oil pan. I've done so much research the past weeks that my head is about to spin off, and I got to the point where it seemed that unless you throw in 18k on LNE mods, your car is going to grenade within the next 100km. But I digress;
This spin-on oil adaptor thing I read about, it says you need it because the original holder has a sprung bypass valve. The modification seemed smart to me, until after 5 minutes or so I realized that my trusty old Volvo 850 spin-on filters have bypass valves too, simply internal. AFAIK, all spin-on filters have this. Sooooo then what is the point of the adapter? Did the designer have a brainfart, or am I missing something obvious?

The LN oil filter adapter allows for use of spin-on oil filters that do NOT have an internal bypass, like the original cartridge type filter. I have the spin-on adapter and use a Mobil M1-107 spin on filter. There are several other equivalent filters that do not have an internal bypass valve. Get it...use it...done.

Not to rain on the collective parade, but, the Napa Gold 1042 - which I have gotten my hands on - has a spring in the bottom still. I cut it open to check. The top collar can move around too. I guess this means the entire filter shifts in the case when overpressure presents itself, opening up at the top, thus it still has a bypass I think.
If it still has a bypass, then ROFL. The bypass is just located at the top, not the bottom?
Edit// It's right there, in Napa's own video! 1m52s into the video. It's got a bypass valve, just at the top! Nobody cared to check in all those years of this being thrown around as 'fact'? I mean, I might be wrong and the 1042 specifically could be a no-bypass filter I guess, but then why does it have a spring?

Interesting find. I don't have a spin on adapter myself, I kept the stock filter. I do use Bosch or equivalent brand cartridge filters with the top/bottom O-ring seals on the ends for better sealing. I also have 2x powerful high temperature capable magnets on the outside of the cartridge housing, they really work, when I did my last oil change after 5k miles I found the magnets had collected a tiny amount of ferrous spooge on them, my filter was spotlessly clean...

Don't confuse an internal bypass valve with a anti-drain back valve. Some of the cartridge type spin-on filters incorporate an anti-drain back valve. Pressure up, anti-drain back valve open. No pressure, anti-drain back valve closed.

Can anyone recommend a reasonably priced oil filter cutter? So I really have to spend $70 on a Longacre brand? Thanks.
