6.0 wastegate

Went on a beach camping trip this past weekend with my 05 f250 psd crewcab FX4 pulling my 8,000lb travel trailer (190 mile trip). Going to the beach ran in tow/haul mode going down, no problems, then coming home Sunday, again, in tow/haul mode blew the lower boot off of pipe coming out of intercooler twice,both times going uphill and transmission changing to lower gear and turbo boost going up to around 25lbs. Was told that wastegate might be clogged up.
Any ideas? Everything on truck is stock. Thanks: wlsmithjr1960http://www.powerstroke.org/forum/images/smilies/icon_ford.gif

A wastegate does not exist on a 6.0L. Instead it uses what's called a VGT (variable geometry turbine) on the exhaust side. Boost is controlled by what's called a VGT solenoid. What typically happens is the unison ring inside the turbo seizes up inside the housing due to excessive carbon buildup, and/or rust and corrosion, causing an overboost/underboost condition.

In your case, I would start by replacing the rubber CAC hose that keeps blowing off first. Rubber tends to swell up after prolonged exposure to engine oil, reducing its ability to seal properly.

You dont have a wastegate. Clean the intercooler pipes real good. and spray the boots with cheap hairspray. Then reattach them.

Thanks for reply, have already changed both boots with new ones, was going up the road around 4:30 this afternoon about half a mile from home and blew off again, I,m guessing from to much boost build up. any suggestions would be greatly appreciated. I live near Thomasville, NC, and don't know of to many 6.0 mechanics nearby. wlsmithjr1960

Springs on band clamps could be loose not allowing them to get tight enough to hold boost tube on.

Made sure all of them are tight. Then same one blew off again half a mile from home earlier this evening. I'm thinkin its blowing too much boost pressure for some reason. Thanks for response. wlsmithjr1960
