Overboost causing turbo hose to blow?

[F250_Lab_Taxi]

This weekend, while towing up a hill, roughly 65mph and 3000rpm we heard a loud ZZZzzzzz then POP. No power, black smoke billowing. We were forced to limp the truck the next few miles into Saint George Ford where the diesel tech diagnosed us with a hose that had popped off of the turbo. He fixed it in the parking lot for us so we didn't have to unhook. Easy and we were on our way, until this morning.

This morning, no noise, but I lost all power and the truck was idling erratically and puffing black smoke. After flipping into neutral a few times I regained power and was off to work. It seemed to puff a little (probably just clearing it out).

My thinking was that the tech put the hose on while the truck was hot and maybe today, when the truck was cold, the hose was not seated properly due to the expansion/contraction factor? I'm guessing that the original blow was due to overboost? Does that sound correct? And, do I need to worry about todays hiccup? Could something else be wrong?

Recent Maintenance (just in case): I just replaced the fuel filters and changed oil. Replaced alternator a few weeks back and changed out batteries.

(Also, praise to the great diesel tech at Saint George Ford who looked at my truck when he was seriously overbooked just so we could get home )

I had that happen once on my worktruck (F550), from what I've read, the common opinion is that because the crankcase breather is routed to the intake tract, there is a small amount of oil that gets put into the intake, which then seeps oil at all of the hoses and can cause one to pop off. If the pipes and hoses are cleaned and reinstalled correctly it should hold. Most people recomend rerouting the crankcase breather to a catch can and to the atmosphere, or without the catch can and straight to the atmosphere.

Hope this helps some, I'm sure someone with more knowledge than me will chime in.

I dont think anything was cleaned. The tech just installed a new boot in the parking lot and we were on our way in about 20 mins. Maybe I should take them all off and replace with some of the more fancy, after-market boots?

F250...curious..was new hose installed or old one reused? I doubt you need to change to aftmkt. JMO. Yes, overboosting can cause hose to blow off...worse case..can also cause h.g. to blow. If you continue to have an intermittant running issue..something else is wrong. Good luck!

btw..if new hose, # should be on your r/o.
