IC hoses loosening up...this is disturbing

[Bad340fish]

Ok, The first time I tightened them up was not to long after I got the truck, it was stock at the time with no guages. All of them were loose, made a slight difference in perfomance. Well I got my gauges and EZ box in a few weeks ago. I tightened all the ones you can get to from the top then. I noticed I got boost sooner and had more max boost. Well its already fallen off again. So today I tightend ALL of the hoses as they were ALL loose again. Am I a few french fries short of a happy meal when it comes to this subject? lol This should not have to be a weekly event IMO any thoughts?

Clark, I had the same problem after initial BOMB's. Just on the initial rubber duct going to the IC. I took it off and cleaned the surfaces that are in contact with each other when clamped as they were just a little slick. When reassembling, I made sure that I had that hose on as far as it would go and kept the clamps real straight as I tightened them (didn't check torque), and made them real tight. So far, tolerating 45psi without problem.

Went through this same problem with mine a few months ago and I can tell you from my experience the problem is not the backing out of the tightening screws on the oe clamps. Someone on this site said it was a harmonic viberation that caused the loosening. Whatever it was it was a problem and I had it slip off several times. Final fix was to double clamp it, no problems since then. I used the original clamp and added a hose type screw clamp up tight along side of it (marine stainless), as said above keep them strait and all the way on. Though I found a couple of the others loose at first it was only the one discribed above I had any problems with also (first clamp to hose below the turbo). 20K+ and heavy hauling and no more slipping off and I just checked it again yesterday, no problems. Hope this helps.

Well is there a way to saftey wire the nuts? Drill holes in them and run safety wire? Worked on jet aircraft, regular aircraft, race cars so why not these clamps? Anybody tried this and does it work if you have?

They already have nylon lock nuts on them... maybe I should try putting a jam nut on them?

Bad340fish,

Its not the nuts loosening up, its the elastomeric rubber creeping under the force of the clamp. Just keep 'em tight and eventually the rubber will take a compression set.

Little Bill... .

Excellent point... . from my experience, it seems to make sense.

For the first 6k I checked these weekly, and did some tightening... . not loose, just had some room to snug up. Now, I don't notice anything.

However, some of these are a bear to get a small 11cm. wrench on..... Is there a secret??

Same here... When I first got my truck, they were loose from the getgo. . I,ve tightened them thrice now, and they seem to have taken a set. . As far as being able to get to all of them, I loosened the clamps the first time and swiveled them around so I could have easy access. . although I haven't had to for a while.

PS in looking @ a bunch of truck, I've noticed at least 3 different kinds of clamps.

I use a 7/16(very close to 11mm) ratcheting box end wrench... . works great to get to all of them!
