K&N oil filter failure...beware
Just a heads up for anyone running or ever considering buying a K&N oil filter for a LS1, after warming up my car for a short drive and parking I discovered a massive oil leak in my driveway, it was down over a quart in about an hour parked. I had a K&N put on with my last oil change 2 weeks ago, it was not over tightened but yesterday it decided start leaking from the fitting at the bottom of the filter used for removal of the filter . This unnecessary "feature" is a huge failure point apparently. it could have been worse though had I not noticed and that POS destroyed my engine....back to AC delco filters from now on...

Not worth the risk when there's plenty of oil filters available without nuts at the bottom of them that are prone to leaking!

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 am sorry but this is not reason to put out a warning for a part failure. All parts can fail and all can have a defect from time to time. Its mass produced and its going to happen. I would bet that you can do a google search and find that every oil filter brand has had failures. 1% of millions sold isn't an epidemic. I myself have fun FRAM for over 25 years on my DD cars and my race engines making over 1000hp and have never had one fail. But that doesn't mean that others haven't had issues with the same filters I am running. I am sure I will get a bad filter one day too.

On the positive side, my RMS is leak free and I got my filthy, probably decade old brake fluid bled while at the shop!

No the nut isn't cast into it...it's spot welded onto the housing...every now and then the spot burns through the canister too much by the welder apparently. As for pics, no I don't have them, the shop threw that POS in the trash after briefly inspecting the filter on the lift with the car running and not running; I don't think they were too interested in dissecting a defective oil filter or taking glamour shots. This was at a GM dealership so they just laugh and point the finger at aftermarket junk part failures.

No idea other than it was 20 degrees first thing in the AM and I warmed it up for 5 mins before a 5 min drive....it was on tight as could be by hand confirmed by myself and the mechanic. It was not leaking out the gasket as the shop confirmed. I'm guessing the rapid temp change had something to do with it because it was completely leak free for several hundred miles before it completely failed on the coldest AM in a while.

I use either; Amsoil EaOs, Mobil 1 M1s, Fram Ultras, or Wix Golds (or NAPA, same thing), and have NEVER EVER had a failure, but I can say the same thing for the OLD, made in the good ol' USA K&N Golds when I used to use them.
