    First the easy one:
    Have a Mopar CAI (yes, an AFE stage II also and I swap them when I clean and oil the filter). The filter is "squeezing" off the plastic collar it's clamped to. It just gradually works it's way off until it starts bumping the P/S reservoir -- so it never gets all the way off).

    I need an adhesive that's going to be semi-permanent, will stand up to the heat and will adhere to the rubber(?) on the filter collar and the smooth plastic(?) on the collar. I was thinking some sort of gasket cement but that may not be the best thing for those materials. I don't want to destroy either of them if I take it apart.

    Now the more difficult one (maybe):
    I've got a BT horizontal pistol grip shift knob (Whoo hoo! thanks BT!). It's just absolutely perfect. Grip, height, I can wrest my wrist on it without getting carpal tunnel syndrome. Awesome. Thing is (I'm got an '06) it doesn't screw on. It's a sleeve that fits over the shifter with a set screw. So you have that set screw clamping a small diameter shaft and you can apply a lot of torque cause the shift knob is horizontal forming a "T"... Just turns out that the perfect height puts the set screw in that groove in the shaft and I've got it torque'd to the max but it's still only "firm" and still rotates too easily.

    I didn't want to do anything before because I wanted to get it positioned just right. So after months of driving with it and rotating it a fraction of a degree this way and that I pretty much know where I want it. Now I want it to stay there... but not permanently. If I have to take the console all the way off again, etc.

    I need an adhesive here that will never completely set up, adhere to chrome and aluminum and I guess would be fairly weak? but it should be able to pretty much stop rotation under reasonable torque. So if I apply some concious muscle to it I can adjust the knob but still have it feel solid the rest of the time. Naturally it has to be removeable. I was sort of thinking of something like silicon sealer.

    It's going to be really tough to apply because of the sleeve thing. There is, relatively, a LOT of surface area in there and it's going to be tough to know what surface coverage I'll end up with. I suppose I could control it somewhat by appling the adhesive down the shaft a ways to where just the bottom inch or so of the sleeve covers it. Any ideas?

    (note: it's going to be warm and sunny here for at least a week so I won't be back till this afternoon. Going to do a major exterior/interior/engine bay wash and install all those BT goodies I stole during the huge end of the year sale :))

    I wouldn't recommend anything for the air filter other than torque the clamp some more???

    As for the shifter, maybe some "Red" lock tight, or a longer set screw?

    I think I've torque'd the clamp to it's max... in fact, I was thinking maybe too much and it's deforming the rubber collar on the filter, and then with the engine vibration it sort of pinches it off the end of the plastic collar. It's only got one way to go.

    Set screw is making contact... if it was a set screw solution it would have to be a larger diameter set screw. I'd hate to risk taping it out and even then the shifter sleave is only so big. Large enough set screw and there wouldn't be enough wall on the sleeve to hold it. The one in there now is torqued to the max. Any more and I'm pretty positive I'd strip it. One problem is that the set screw is clamping against that chromed(?) shaft out of the shifter -- tough to get a bite into that.

    3m makes some really cool adhesive foam tapes that have a very high shear strength. Might be worth a try.

    Have you tried Tclamps or roughing up the surface to get a better clamp?

    No clearance for tape. and I'd never get the thing to go on in the first place.

    oooh, now there's an idea... I think that's going to be a winner! You're a friggin genius :grin:

    I'll use some really coarse sand paper or a fine rasp on the smooth plastic. and that shiny inside rubber surface should really grab on that.

    What about a longer set screw and you drill a small hole into the chrome shaft so the screw actually goes into it alittle.

    Well... yes, that would work... but I'd say that would be a MAJOR project for me (no drill press or anything) and there would be about a 95% probability that I'd screw it up.

    I'd have to remove the shifter assembly. Don't know if the shaft unscrews or not. Then I'd have to drill it in the exact spot. about 1 degree off is going to be a fail. It's a small diameter shaft and I expect the chrome and the steel under it to be pretty hard. I'd have to go to a machine shop.

    Actually I would rough up the rubber too if you can.


    Another question what is the shifter knob made from? Would it be possible to put a couple more places for a set screw so you would have 3 screws grabbing not just one?

    It's a BT shift knob (and they don't make this model any more so eat your heart out). Sure you could put an additional set screw or two but... I'd have to drill and tap them... No drill press and I just can't see a happy ending using a hand drill. It actually comes with 2 set screws in the sleave but with the height I like it at the top one is not engaged.

    I think if you have a vice and a steady hand you could pull it off or another idea would be to get the small drill press they make for dremel tools. Since aluminum is kind of soft you probably want to put a heli coil or something in to reinforce the threads.

    Not sure how big the hole is in the shifter handle, but maybe BT can make a sleeve that fits the handle with a threaded ID. Or maybe it is nearly the right size (drill it out if need be) to accept a thread insert or Heli-coil that fits your shifter shaft. You can get a matching thread jam nut to lock it off. Then you will not need the set screws.

    On the intake, if the sandpaper does not help, take a soldering iron or just a flame to the edge and then mush is a bit around the circumference, to create a small flare.

    RTV silicone for both.

    We talked about a custom sleeve when I got it... It would be worth it if they were going to sell about a thousand of them. Ideally what I would want is one that has an angle that moves the shifter knob forward about 1". To where it just doesn't pinch my fingers against the A/C knobs when putting it in park. That would position the shifter knob perfectly under my palm when in D. Got the padded leather console cover and drive with my elbow/forearm resting on that. So the knob should end up squarely under my palm and at a height to keep my wrist perfectly straight instead of sort of reaching down for it. oh well.

    I'll try the silicone on the shifter.
    I'll try roughing the filter collar. With it roughed I could still take just the filter off without dissassembling the whole thing (although I do that anyway to swap them).
