Loud Rattle No Power NO Boost ... Turbo?

Hello ,

I have a major problem I believe..... I was coming home from thanksgiving and topping a small hill and when I stepped on it a little from coasting I lost all power and boost.. Shut the truck down immediately (before I was stopped.. coasted to a stop) .. I was on a major highway and backed it up about 50 feet into a field entrance... at idle there is a loud rattle clanging sort of sound... Previously before this happened the truck would go into Regen bout every 50-100 miles ... not sure if i have blown turbo(s) plugged DPF or something else .. anyone have any insite on the problem ...

Its a 2008 F-250 6.4L with 214,000 miles ... any help would be appreciated .. hate driving my back up truck with this one sitting in the driveway ...

Thanks
Monte

Still no luck getting my truck back to where I live now ... Finally found a truck and trailer big enough to trailer it back but no time to do so as of yet .... Had several people offer suggestions to what is wrong... let me know if any of these sound logical..
1. Plugged DPF filter.
2. Bearings in Turbo.
3. Turbo boot.

This is my first diesel and rather green to everything and right now cannot afford replacing Low and High turbos ... if it wasnt against the law im ready to light a match to this truck ! love it but cant afford all the repairs anymore ...

Anyone have any ideas or suggestions please let me know .. im getting worried its going to be a $3,000 repair or more ...

Thanks

Thank you everyone for the ideas ... still stumped ... im out working on it right now and no shaft play on the high pressure turbo.. after starting the truck briefly the sound is coming from the low pressure turbo and sounds like the bearings are just rolling around in the case ... with no boost on the guage ... pretty sure its a smoked Low Pressure Turbo... disconnected the DPF thinking part of the problem and pretty sure it is plugged.. after disconnecting it then i started it and smoked all to hell unlike before.. bout 3 handfulls of soot fell out of the dpf/cat when i split them.
does anyone know how hard it is to remove just the high pressure turbo?

very hard, if you don't want to remove the cab you could pull the trans to get the up-pipes out. other than that i don't have any suggestions for you. i've never tried to get the turbos out cab-on/trans in. they say it can be done...........but i don't know who they are

i have also heard of the low pressure turbo being seperated on the truck, but once again i don't know exactly how this is done. in theory the only exhaust to be removed is the downpipe and it's only connected to the high turbo by a gasket. i have gotten the low turbo up enough to change the oil drain so i think it may be possible

ahhh I C ... well thats all I need to hear ... haha . Never fails I get to a point where I think that I can tackle something and I get to a certain spot and start yelling at myself for attempting it and not just taking it to the shop ... Either way A dealer wont be looking at it ... Both Dealers here in Des Moines Iowa both are crooked and thieves and would rather let the truck sit than let them touch it .. hahaha ... Well I appreciate your input and will post if I find anything new or once I get it fixed as to the real culprit... haha Thanks a bunch!

Just a FYI, I don't think you can tell by looking at the DPF if it is clogged or not. You can not see through it, even win new.
