Blown Intercooler Hose
I blew the turbo to intercooler hose at the clamp - sounded like a 9mm when off in the front end. My roadside inspection showed nothing except my ignorance. So I drove it to the closest dealer - about 30 miles down I-75.
Mechanic was too busy to look but conversation led me to look at the intercooler hose connection. I reconnected the hose and tightened the clamp.
Question, is there anything I can/should do to minimize the damage done by sucking in 30 miles of unfiltered air?

Yes, it lost power - felt like a 4 cylinder Cadillac - it would run at highway speed but not quickly. Scared the P -Jesus out of me - I'm looking for new and better clamps any suggestions?

I'd retighten the clamp and try it again. If it happens again, then I'd investigate a little further.

I would think if you blew the intercooler hose off you still would be sucking a certain amount of unfiltered air as it is post air filter. Therfore it is not getting the boosted/filtered air but unboosted dirty air, that's why he lost power(no boost). I think that's how it works.

It ain't gonna suck in if it's blowing out

you are smarter than a 5th grader!
as long as he did not drive down a dusty road during a dust storm he will be fine. refit the hose tighten the clamp check all other clamps and keep on truckin'

If the hose blew out at the intercooler inlet, unfiltered air was being pulled through the intercooler and into the intake manifold. The motor will pull air through the intercooler with no boost, otherwise it wouldn't have run at all.
The turbo became a big fan under the hood when the inlet tube blew and had no effect on the air intake. If any part of the intake between the filter and intake manifold fails, there will be unfiltered air entering the motor.
With that said, I doubt there will be a problem, unless as stated before, you were driving some gravel roads or in dusty conditions.

Well, it actually depends on the nature of the blow-off.
A completely disconnected IC boot will allow the engine to operate as a normally-aspirated diesel, so it will pull a vacuum on the new opening and draw in unfiltered ambient air.
A partially blown IC boot normally allows the turbo to keep the intake tract pressurized - albeit at only a few psi (gauge) - which is enough to prevent unfiltered air from entering the engine.

I can't quite get it to stay on now, been playing with it all day, at about 36 psi it blows again.
Even when it blows, since this is a partial, I can here pressurized air blowing out, but I can only pull 7 psi with the boot partway off.

If I make a suggestion... (From a prior ford owner) One of the reasons they blow off is the added boost we make and the clamp may have not been tight.
To keep this from happening again, take some lacquer thinner, MEK, something that will clean and dry, wipe pff the IC inlet pipe very very good, then wipe off the inside of the hose. Re install dry and re-tighten the clamp.
Having clean dry surfaces mating and the clamp cinched goes miles from this happening again. Now, if you are running 70 lbs... All bets are off

I just replaced all of my trucks hoses with a very nice set from Diesel Distributors:
http://www.dieseldistributorsusa.com...its-p/icb3.htm
For $130 and free shipping, these are great!
Working pressure, or constant pressure is well over 100psi. Burst pressure is over 300psi.
These are made with another full layer of silicone and weave, they are much stouter than the other guys 4 plys.

The reason the Ferd's blow off so much is they suck the crankcase air back through the intake and burn it (PCV). All the connections weep oil after a few thousand miles. We on the other hand vent to the atmosphere and only pull air through our intake, so if clean and dry at assembly they should hold fine.
