Soot around the variable turbo and back of hood

[MD05]

New to me 08 F450, I just found some soot around the drivers sid eof the Variablble Turbo and the linkage (?) also on the back center of the hood. Any Ideas as to what can cause this/??

Sounds like you've got a small leak in the line somewhere. I'd clean it off real good and run the truck a couple of days and then look to see where the soot is concentrated the most and that should give you a source.

I had same thing on my '08. It was the up-pipe, which is the pipe coming off the header and goes into the DOC and turbos.

Mine has the same thing. It is the up pipe on mine. I just keep driving it like I stole it. When it wont his 45lbs of boost then I will fix it.

Mine has the same soot at the linkage on the variable turbo. Is it right where it goes into it on yours? I actually have a picture of where it leaks on mine as well. Apparently it is normal

That may be what he is talking about. I also have that, but behind my turbos where that aluminum fiberglass shielding is mine is all black coming from the back side of the turbos.

There is a TSB on the soot problem.
The fix ID's a gasket and new vee band clamp.
I found my v-ee band clamp not even hand tight, replaced the clamp and gasket --- no more soot problem. fix cost $30.00 in parts and about 1.5 hours to accomplish.

PS for those who drive like you stole it and still have the cat and DPF... the soot is the fuel being injected on the exahust stroke to perform the re-gen.... it is hot or in the process of burning, I sure would not like that to escape inthe engine bay, might even burn the heat shielding tooo.

Some food for thought...

Mine leaks at the actual actuator though (see picture). So I don't think a new clamp would fix mine.
