turbo diesel blows hose

[markdpro]

My F350 turbo diesel blows the hose connecting the turbo to the intercooler.
Several trips to the dealer and no fix.

Any ideas???

bad blow off vavle?

Stupid comment - is there a hose clamp? It does sound like a bad blow off valve but what yr is it? The dealer should have fixed it. Unless something got into the intercooler and the pressure is building to high, I'm not sure what to tell you.

Well look what my brother in law found!
Intercooler Hose Blow-Off; Oil Leaks at Intercooler Hoses:
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. Replacement hoses have a revised inner liner that has adhesive properties. Use the following parts as needed to service the condition:
Short upper hose, equal length elbow: 6C3Z-6C640-C; metal tube: single alternator 6C3Z-6K769-B or dual alternator 6C3Z-6K769-A.
Long upper hose, unequal length elbow: 6C3Z-6C640-A; 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 6C3Z-6K786-EA.
Lower hose, all: 6C3Z-6C640-B.
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. Undamaged hoses may be reused, but they must be cleaned and inspected. If the inside of the hose is blue, it is recommended to apply a thin uniform coating of Motorcraft TA-31 RTV silicone to the mounting surface after cleaning. After reeassembling, allow the silicone to cure for three hours before driving the truck. 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.
TSB 07-5-15.
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).

Sounds like the problem has been fixed. Good luck
