    Default worst stuck oil filter on a 912 ... ever.

    My 912 UL has a stuck filter. Its on a model IV. I put it on by hand 50 hours ago, I can't believe how stuck it is. I was using a strap wrench and have damaged the filter already, so, wondering, who has had this issue. I haven't cracked it or creased it badly but short of taking off an exhaust pipe to get a better grip, I"m kinda stuck, any ideas?

    Many years back I to use a large channel lock pliers once. Learned not to over tighten from then on.
    Also in a last ditch effort, long Phillips screw driver punched through the filter can out towards the edge of the filter so you donít get near the threaded part of the engine will give you lots of leverage. Kind of messy but like I said. Last ditch effort.

    Are you trying to remove a Hot filter or Cold? Assuming it was cold, it May make a difference if its Hot. I have experienced this with my Truck. In my instance, the rubber gasket tore clean off of the filter, remained on the engine. Because I was laying on my back under the truck and my vision isn't good up close, I failed to see the gasket stuck to the engine and because I dropped the filter straight into the oil pan I never seen the missing gasket. Needless to say, I blew that out when I put a new filter on over that gasket and started the engine. Big mess.

    once in a while I get a good stuck one. take a big screw drive and jab it into the filter, if you can go through the whole thing and pop out the other side it helps, than hold pressure on it and it will finally let loose. when putting the new one on, make sure and coat the seal with fresh oil and only tighten 3/4 turn once it makes contact.

    If you coat the seal with DC4 (Dow Corning), you can likely avoid this issue in the future.

    Success!!!!
    Somebody said put some sandpaper around the oil filter to give the slipping wrench some purchase.
    That worked!
    Oil change complete. Doing a test Run UP in a couple minutes.
    Thank you all.

    Sandpaper works; I personally use a strip of ScotchBrite, which also works well for installation if your hands are oily.

    I end up using the screw driver because somehow I always leave the filter wrench at the shop, geee. yes I use that small size all the time at work.

    I did this exact thing with our Honda Fit, started it up and heard a weird "pop", Big Mess is an understatement. Glad I have never
    done it with my plane ... I had to Sealcoat the driveway (asphalt) as there was no making it look nice after. looked like the Exxon
    Valdez had parked there ...

    Not to mention I invented about ten variants of the F-word in the process as well ...
