Sounds like a tricky marketing ploy to sell who knows what it is. There is no little R for registered trademark on the copied name. I guess it is the cheapest generic made in China off brand resold to maximize profit.

It matters for those who like thick oil, live in the cold climates, and the bypass valve can’t handle the flow so the oil pump relief opens. We see filters like Roki showing many holes in the media, and other oe filters too. They aren’t unaware of filtration so why do they make filters like...

Whip city has a cut open of a Pentius today and a few days ago did a light test on two filters, an Amsoil and a Fram. Both Amsoil and Fram made failed the light test. The Pentius seems to be a winner as far as looks goes. The TG is interesting as it shows how they used to make the fiber end caps...

Date codes are starting to matter. The latest Fram made ecore style center tube filters have metal end caps. They haven’t done good engineering with the changes. No engineering at all, and it doesn’t take an engineer to see it. Bean counter engineering maybe it could be called.

Portfolio of clients, a list of them. The clients are free to have other vendors of their filters too, or go elsewhere. I found the made in Korea Pentius PLXL to look about perfect cutting a new one open. As long as the media doesn’t restrict too much by chasing low micron numbers they should be...

I never said Dave didn’t put new gaskets in, but the engines he gets in for repair I bet quite a few have hardened gaskets. Also it isn’t known what gasket he put in or a mistake wasn’t made. You have no more idea than I do. I didn’t bring thst aspect up, you did. I went to ebay to look at...

Everything I said was correct. The small common section of gasket separates the in and out to the oil filter. The housing might seep a little on the block also, not gush, but not if just the common section leaks. Some adapters have a separate block gasket, this one doesn’t. Search ebay for used...

It could be this oil filter adapter gasket fails, which acts like a leaky adbv or oil bypass. This one is for the engine they are working on.

I looked it up on Amazon, looks the same. They use the black glue, but on plastic not metal. The metal caps may be oily or something from production, not washed properly, and why we see end cap poppers. Really nice filter.

If Mobil did their testing, which I am pretty sure they did, it should be a good filter. They selected a black base gasket, which is probably not silicone. Maybe to not change too much for no reason, when the black ones were not a problem. Another reason for them to switch is price. MH may not...

It functions just like a u trap. That was the context here. I can tell you from experience of being on the roof clearing the vent pipe that the kitchen sink does not drain if the vent is fully sealed. Sometimes air from the sewer pipe will make its way up and there are glugs of air so the sink...

I like the old design, the ecore, better. I used one on an older vehicle. Oil pressure went up fast and there were no issues. I have one more left. It has the combo bypass/ adbv. Some don’t like the valve. It seems like it was a good invention to me. All one piece rubber, very simple and...

It can achieve AABV status even with a knock or vibration. There is no center holding. I don’t think anything as bad as this has been accomplished before. Shown Delco may have the gap have to look at it with a light.

There is a pipe coming in and one going out of the filter mount. There are gaskets preventing the two sides mixing coming in and out. Or the mount is cast into the block with the in- out pipes apart. It is like a u trap in operation. There is a big oil pump with precise small gaps that the oil...

They offered the best customer service of any by sending out spec sheets.

Look at the gap at the edge of the holes on the Fram shown. The topic filter may or may not have it. I saw it on my Fram and ST 3614 so it isn’t rare. This is a new design..

Perfectly fine? Look at the picture of the adbv in this thread. I bought one PH3614 the same as his picture, and a Supertech I just got from Walmart last week with the new design, has the adbv not sealing. These shouldn’t be sold. There is no adbv function. Besides other issues of quality inside...

The others might be ecore, different base holes and combo bypass valve. The kind you show, Fram new design, should be taken off the market.

I wonder what causes it because the tax isn’t a big part. I suppose the internet knows. I see no reason to whine it doesn’t change it. You are welcome to pave your own roads you use with your own materials in place of the 45 cents per gal or whatever it is. Of course you can’t possibly pave the...

Unless an oring is bad on the oil filter adapter or further down, the oil filter and lower pipes aren’t vented and stay full. The filter always stays full, it’s like a u trap. An adbv helps keep the oil above the filter from draining. I doubt the bearings are being damaged by oil starvation...
