Wix bypass valves?

[jeepman3071]

In the video below the guy talks about the bypass valve of the wix not having a seal, and that the K&N filter is better constructed being all one piece. What would be the negative effects of the Wix bypass? Motorcrafts have the one piece bypass valves also, similar to the K&N. So would that be a better choice over the Wix? I always thought of Wix as being a high quality filter.

I believe Wix is a high quality filter but this is the one thing that I have questioned in the past as well. You would have to think a one piece design would be more leak proof than the Wix two piece design but will it make much difference to your engine? The possible amount of oil that could bypass the element through the slip fit bypass would be fairly small I would imagine.

What if 10% of your oil bypassed the filter? I doubt it would do any harm. It will be mixed in with the other 90% filtered oil and most will get caught in another minute or two by the next pass.

If the metal-to-metal interface of the bypass valve is good and flat, it should seal pretty well. Might be a hair of leakage, but so small it shouldn't really matter much.

Any leakage of that design is TOTALLY inconsequential. Sure, its not as AIR-tight as a rubber-on-metal seal. But its not trying to seal AIR either! Its a very good oil-tight seal.

The Wix cartridge filters for the 2.2l Chevy are made in Korea. I'm not going to use one.

What is the advantage of having the bypass valve near the thread side of the filter (front?) over having near the back of the media? I know Motorcrafts have them in the front while Purolator Classics have them at the back near the spring, even though both are manufactured by the same company.

The Wix 57082 I recently purchased says Made in Poland (not Korea).

The advantage of the base end bypass valve is that when the bypass valve opens, the oil has a direct in/out past the filter media, and doesn't potentially pick up debris in the filter and flow it unfiltered into the engine.

IMO, the only time debris might be washed away from the media with a dome end bypass is when the filter is super loaded up with debris. Dissection of many oil filters shows that the crud always settles way down deep in the filter pleats, so washing that away and through the bypass valve when it opens is going to be low probability.

Plus, even with the bypass valve open, there is oil still trying to flow through the media which keeps all the debris down in the pleats and prevents it from moving around.
