K&N oil filter failure...beware
Last edited by Paul Bell; Jan 14, 2016 at 08:00 AM.
I would not hesitate to use a K&N filter if that was the "best" available when I went to buy a filter.
Mobil One Extended, WIX, K&N, Hastings, all good filters. Because of consistently poor components and build quality, Fram is still the brand to avoid. And since ACDelco is now a low bid contractor, there have been instances where they've been shown to be made identically as the cheapo Frams. Do your engine a favor and spend just a few more bucks on a better quality filter.
There are some "high end" filters that are waayy better, including one version from Fram.

Hmmm technical...Reply to a thread about an isolated issue that doesn't warrant an alert of any kind & is also posted in the wrong section of the forum.
Reply: Have never had a single issue w/ a K&N oil filter. Like most people of whom are capable of replacing an oil filter, it's probably because we actually look @ it & then install it properly.
Raised by a single woman were we? lol

It was indeed "installed properly"
Working on an 03 Tahoe with a 5.3.
Customer says they had their oil changed recently at another shop.
It was leaving large puddles of oil in their driveway.
So they bring it into my work, I get on a lift, and the filter is covered in oil.
Its a KN obviously, by that pic.

I guess you get what you pay for, half the reliability of a normal filter at just thrice the cost!

Here's yet another thread from some subuaru guy about this known issue with their shoddy spot welds inside the filters causing huge leaks from the 1" nut .

I would imagine the "nut" on the bottom is used for removing only.
I have worked at Chevrolet dealerships before and they used hourly kids to change oil, barely
knowing the difference between a screwdriver and a wrench.
Most Purolators are junk. Reach to a higher shelf.
Purolators are junk? There were a couple independent tests done a while back and one of the top designs was a Purolator along with wix. I would like to know your info.
It's certainly easier to find a better filter for just a few bucks more. I believe all retailers carry Mobil1, which will do very well.
