Some days you have no luck.

Started the prep work for storage. Washed the car and then went to change the oil and the first bit went nice and easy until the end which then made a Gigantic mess. Turns out I had a bad oil filter (k&n 2004 same as the one it was replacing) that would not seat. It screwed on and felt like it tightened up but in reality it hadn't. Started the car and no oil pressure and in the 10 to 15 seconds it ran dumped about 3 quarts of oil on the ground. Uninstalled the new filter put the old one back on it went back on perfectly opened up a new case of the oil moss sells and found that every one of the bottles had leaked in the plastic bags and coated the bottles. Cleaned up that slimy mess and poured in 3 quarts. Started the car up no leaks and good pressure. Tomorrow I'll get a replacement filter. So a job that should of taken about 15 minutes took an hour and made a heck of a mess. Also found I have a leaking valve cover gasket so that will be fixed in the morning and it's back to the carwash to degack the engine from this evenings fun.

Stewart, I've been using NAPA premium filters lately and haven't had any issues with them. No oil pressure change and no leaking seals. PJ

I had the o-ring of the filter cannister fail on one of my MGCs on a road trip out to Vancouver, BC.

It's amazing hour fast one can lose 8qts of Castrol...and the under bonnet mess it makes.

I ALWAYS watch my gauges...and saw the oil psi go to ZERO...and fortunately carry a spare filter/o-ring with me...so it was an easy fix...and..I was right nest to a truck stop, so I found oil without difficulty.

Would have been a different story had it happened ou in the middle of Montana or the Badlands...or had I NOT been checking the gauges!

The force was not with you that day. I use Fram and Castrol from Walmart on all my cars and have had no problems. Did the seal surface have anything on it like gunk, a piece of an old seal? I've heard of folks pull the old filters and the seal or pieces stays on the flange. But if you had a defective K&N, well that's just a bad day.

The Napa Premium, if you mean Napa Gold, are made by Wix, who has an eviable reputation as one of the best filter manufacturers.
