I am new to this forem so bear with me.
I just bought a 2004 ford super duty 1/2 ton with a 6.0 L. power plant. First time out on the road pulling a 12,000 load the hose on the hot side of the turbo charger hose blew off at the intake manifold. I put it back on 4 times and it just keep blowing off. I had it towed to ford and they put on a new hose and clamps and told me if it blows off you must put it back on with a new hose and clamps because of it gets any oil on it it wont stay on.
So far so good up to now. Any body had any trouble keeping the hose on? The dealer seamed to know all about it because he says many trucks had been towed in to him with the same problem.

This is actually known problem. Ford has tech notices on this problem. I thought they had a fix for it. Ive seen the link on this forum. Maybe I can find it. Here They are.

Some trucks may exhibit oil leakage from the hot side intercooler hoses. If one of the hot side intercooler hoses blow off it will cause the truck to exhibit a low power/low boost condition. Hot side intercooler tubes are no longer available as an assembly. Use the following parts as needed to service the condition:
Short upper hose, equal length elbow: 5C3Z-6C640-AA; metal tube: single alternator 3C3Z-6K769-DA or dual alternator 3C3Z-6K769-CA.
Long upper hose, unequal length elbow: 5C3Z-6C640-BA; metal tube: single alternator 5C3Z-6K769-AA or dual alternator 5C3Z-6K769-BA.
Use this hose and tube combination if the hose blows off
Clamps: upper hose 6C2Z-6K786-AA; lower hose to tube 6C3Z-6K786-CA; lower hose to intercooler 1C3Z-6K786-DA.
Lower hose, all: YC3Z-6C640-KA.
Clean the hose mating surfaces to ensure the hoses will stay in place. Seat the hoses completely onto their mounting surfaces before tightening the clamps to 9 ft/lbs. Test drive the truck while monitoring the boost pressures, which should be 22-25 PSI. An overboost condition will cause the hose to blow off.

On 2004/05 trucks that exhibit the cold side hose/pipe blowing off at the intake manifold, replace the plastic tube with part #6C3Z-6C640-AA as in recall 05B29 (trucks built from 12-15-03 to 4-1-04), or repair as in TSB # 05-22-3 (trucks built from 4-1-05). Clean the intercooler and intake flange with brake parts cleaner. Seat the hose/pipe onto the intake manifold and torque the clamp to 9 ft/lbs (12 NM).
