    Received a call from a friend today who was changing his oil on a 350 SBC, said he drained the oil but could not remove the K&N oil filter that has a nut on the bottom of the filter housing to facilitate removal. He said the largest wrench he had was 15/16 and was too small. Gathered up some one inch and better wrenches and sockets along with a couple of oil filter removal tools and went to help. This K&N oil filter had a one inch nut tacked on to a small metal bracket on the bottom of the filter. The removal tool I usually use fits over the bottom of the filters but due to the K&N nut the tool would not seat on the bottom of the filter. Tried a one inch socket but it wouldn't seat on the K&N rounded nut and the filter wouldn't budge. Superman must have installed this filter.
    Oil filter removals are not rocket science. Whats with this K&N and the half assed rounded one inch nut? Why not use a square sided nut so normal hand tools could remove it? Why make a simple task difficult and charge about double the price of a competitors quality filter? Finally removed the K&N POS with a claw device that tightens and squeezes the filter as you rotate the filter in the removal direction. Needless to say it will be a cold day in Hell before I ever buy one of these K&N abortions.

    Take them off and check for crap that made it's way through them. That's why they breath better. They allow more air in and that air has dust and grit in it.

    2 .silly spin on filter
    3. new fangled modern hoopla.....

    if its stuck, and you need it off, bash a screwdriver through the side all the way out the other, instant hand hold :)

    Over the years there have been a few times I've thought of using a screwdriver but if it doesn't come off then your down to a hammer and chisel. Fortunately I've never had to go that route.
    Due to my experience and other comments, I Googled K&N oil filters and guess what? Others have had difficulty with that half assed rounded one inch nut. What a piss poor design.

    I tried this on a 2.3 Ford motor that I pulled out of my old '29 roadster.
    It was on an engine stand, and I had good access to it, but couldn't get it to budge.
    The screwdriver through the side ripped the canister in half!!! Had to use a chisel at the seam on the base!
    I had the oil changed at Jiffy Lube as I ran out of time on my way to Daytona for the Turkey run....never again!

    Wait, I thought Fram sucked, now K&N's on the list too?
    I agree K&N is over priced. But I've never had a problem using a 1" 6pt socket on a K&N filter. Always thought it was pretty dang handy on the rare occasion I deal with one.

    I thought that's why they made those large water pump pliers

  14. i am betting the nut on the bottom is to remove them only......not install them.
    light coat of oil on the gasket and hand tighten only.
     
  15. Any of you folks with the removal problems put the filters on yourselves? I've never had a problem with any brand that I put on myself with a little oil on the ring and 1/2 turn after the gasket makes contact.

    droptop70ss, thats what I'm talking about. K&N a real POS. I only ran into one on a friends car. I never used one and never will.

    I think the biggest problem w/K&N is the 1"nut. Guys use a half inch drive ratchet and crank 'em on like they're a lug-nut. Bad Juju...:eek:

    slowmotion, your probably right. I wonder why the manufacturer never figured that out? You'd think a non rounded 3/4 nut would do the job.
    I'll stick with the easy off NAPA Gold (made by Wix) filters that goes for less then half of what K&N gets. Just paid $6 and change for a NAPA Gold 1060.

  19. it is probably written clear as can be on the side of the box........that nobody reads.
     
  20. Install the new K&N Wrench-Off Oil Filter™. Hand tighten the filter clockwise until the rubber gasket contacts the adapter; then tighten the filter an additional ¾ - 1 turn. 8. Fill the engine with the Lucas® 30WT Plus Engine Oil to the Full or “F” mark on the dipstick.

    Guys ,when a oil filter kicks your ass it's time to call it a day, lol. If they don't come off with just a strap wrench ect, then they where put on too tight ,it happens.

    I always use one of those strap wrenches that tighten the web strap the harder you pull. First time I changed the oil in the 350 that was in the Lincoln, the strap wrench wouldn't budge the filter, ended up tearing the can off the base! Two hours later with a hammer, a bigger hammer, two or three chisels, a air chisel, a long bar or two and lots of cussin' and fussin', I finally got the base unscrewed from the engine! Can't remember what kind of filter it was, but it was for sure put on too tight.

    I agree. All of the removal problems have been because people don't believe that a little bit of oil on the gasket and hand tight is all that's needed. Ask anybody that has ever met me. Hand tight is hand tight.

    Andddd another reason not to convert a flathead to a full-flow system! (I HAD to do it!)
     
  28. Yup, bad install, nothing against K&N.

    I had one OT daily that liked to hang on to filters. After removing the first tough one with a Channelock (after seeing a screwdriver would detroy it) I went on to installing some left over skateboard grip tape on the new filters for the next few years I owned it. Made hand removal easy peasy.

    U don't have large cresant wrench or a pair of channel locks?K&N oil filters are well known for taking a higher pressure than normal and used in a lot of racing apps.
