I've stayed pretty neutral about the whole tearolator hate train because I think while tears are bad, it's not significant enough to cause much of a bypass because the tears only account for maybe 0.01% of the total surface area on the filter media.
Anyways, the Bosch 3422 was used on a Lexus ES330 /w around 100k miles for close to 9K KM (around 5.6k miles) over the last 6 months with lots of cold starts everyday and short tripping. PP 5w20 was used and engine doesn't burn any oil or have sludge.
1 tear @ the top of the filter with a wide V spacing pleat. The bottom of that same pleat is narrow and didn't tear, rest of the filter looks perfect. Silicon ADBV is factory fresh super pliable. Can someone translate the date stamp?
Mopar 0FE00308 (similar to L14476) which looks like is also made by purolator using the same top bypass mechanism as the Motorcraft filters. Used on a Toyota Matrix 1ZZ-FE /w 85k miles for unknown miles, probably around 5-6K. Got the car used recently and changed all the fluids because all of them looked overdue. No oil burning AFAIK.
Slight sludge at the bottom of the filter but not much else going on, no tears anywhere just wavy pleats. Nitrile ADBV is very stiff but it doesn't really matter for this particular engine since the filter hangs down from the block so there is always oil in it.
I used the exhaust pipe cutter from Princess Auto which wasn't ideal because the cutting wheels have room to wiggle which causes a very wide area to be cut. Going forward I'll probably try to get some washers for the wheels.
I still have a Bosch 3422 filter left and will probably still use it, but won't be buying Purolator again. IMO, the ADBV is more important than 1-2 tears if the filter is mounted sideways on the block. I've seen a few videos of engines ticking at start up because of cra.ppy ADBV in filters. Exception being an engine with sludge, then tears are a bigger factor.
